How to Create Guitar Chord Diagrams in Alternate Tunings

Alternate tunings can completely change the sound, feel, and harmonic possibilities of the guitar. Lowering or raising even one string can create new chord shapes, deeper bass notes, wider intervals, and open-string combinations that are difficult or impossible to achieve in standard tuning.

However, alternate tunings also make familiar chord diagrams less reliable.

A shape that produces one chord in standard tuning may produce something entirely different in Drop D, DADGAD, Open G, Open D, or another custom tuning. The visual fingering may look familiar, but the sounding notes have changed.

That means a chord diagram for an alternate tuning must be built and labeled using the actual tuning of the strings.

With FretGlyph, guitarists, teachers, songwriters, and publishers can create custom chord diagrams for alternate tunings, hear the resulting voicings, automatically identify likely chord names, and export the finished diagrams as PNG, JPG, or SVG files.

This guide explains how to create accurate guitar chord diagrams in alternate tunings, how tuning affects chord names, and how to organize diagrams for lessons, songwriting, books, and personal reference.

What Is an Alternate Guitar Tuning?

An alternate tuning is any tuning that differs from standard guitar tuning.

Standard tuning, from the sixth string to the first string, is:

In an alternate tuning, one or more of those open-string pitches are changed.

For example, Drop D lowers the sixth string from E to D:

DADGAD changes several strings:

Open G is commonly tuned:

These changes affect every fret on the altered strings.

A note played at the third fret of the sixth string is G in standard tuning. If the sixth string is lowered to D, the third fret becomes F.

Because of this, chord recognition, playback, and labeling must all use the correct tuning.

Why Guitarists Use Alternate Tunings

Alternate tunings are popular because they can make certain sounds and techniques easier to achieve.

They may provide:

Lower bass notes
Easier power chords
Open-string drones
Rich suspended harmony
Easier slide-guitar shapes
Symmetrical chord patterns
Wider intervals
New songwriting ideas
Simpler fingerings
Different resonance

Alternate tunings appear in many styles, including:

Folk
Blues
Rock
Metal
Fingerstyle
Celtic music
Country
Ambient music
Experimental guitar
Singer-songwriter music

A tuning can influence the entire character of a composition.

Why Standard Chord Diagrams Do Not Always Work

A chord diagram shows string and fret positions, but those positions only produce the expected notes when the tuning is correct.

For example, a familiar E major shape assumes the sixth string is tuned to E.

If that string is lowered to D and still played open, the chord contains D instead of E in the bass.

The resulting chord may sound like:

E7/D
A different inversion
A suspended or extended voicing
A chord with an unintended bass note

The shape has not changed, but the harmony has.

This is why alternate-tuning chord diagrams should always identify the tuning clearly.

Common Alternate Guitar Tunings

Before creating diagrams, it helps to understand several widely used tunings.

Drop D

Drop D tuning is:

Only the sixth string changes.

Drop D is popular in rock, metal, folk, and fingerstyle guitar because it provides a low D bass note and allows one-finger power chords across the lowest three strings.

DADGAD

DADGAD tuning is:

It creates an open, suspended sound and is widely associated with Celtic, folk, acoustic, and fingerstyle guitar.

The open strings do not form a simple major or minor chord. They create a D-based suspended sonority.

Open G

A common Open G tuning is:

When all strings are played open, they form a G major chord.

Open G is popular in blues, slide guitar, roots rock, and certain rock rhythm styles.

Some players avoid or remove the lowest string because the open sixth string is D rather than G.

Open D

Open D tuning is:

The open strings form a D major chord.

This tuning works well for slide guitar, fingerstyle, folk, and open-string songwriting.

Open E

Open E tuning is:

The open strings form E major.

It produces higher string tension than standard tuning, so some guitarists prefer to use Open D with a capo at the second fret.

Double Drop D

Double Drop D tuning is:

Both E strings are lowered to D.

This creates strong D drones in both the bass and treble.

Half-Step Down

Half-step-down tuning is:

Every string is lowered by one semitone.

The visual chord shapes remain familiar, but every chord sounds one semitone lower than it would in standard tuning.

Full-Step Down

Full-step-down tuning is:

Every string is lowered by a whole step.

The shapes remain familiar, but the sounding chords are a full step lower.

Custom Tunings

Many guitarists create their own tunings.

A custom tuning may be designed around:

A song’s key
A particular drone note
A vocal range
A fingerstyle arrangement
Extended bass range
Symmetrical intervals
An unusual chord

A flexible chord diagram creator should allow each string pitch to be entered manually.

Step 1: Identify the Exact Tuning

Before building any chord diagram, write down the tuning from the sixth string to the first string.

For example:

D A D G A D

Do not rely only on a tuning name.

Different players sometimes use similar names for slightly different tunings. Writing all six notes eliminates ambiguity.

When using FretGlyph, select a preset tuning or enter each open-string pitch manually.

Step 2: Confirm the String Order

Always enter tuning notes in the correct order.

Most guitar tools list strings from:

Sixth string to first string

That means:

Lowest-pitched string first
Highest-pitched string last

However, some interfaces may display the first string first.

Confirm the order before continuing.

Entering the tuning backward will produce incorrect playback and chord names.

Step 3: Decide Whether the Diagram Shows Actual or Relative Frets

Most chord diagrams use actual fret numbers.

If a note appears at the third fret, the guitarist presses the third fret of the instrument.

However, capo-based diagrams may use positions relative to the capo.

For example, a diagram might treat the capo as a temporary nut and label the first fret above it as fret one.

Choose one system and explain it clearly.

For most standalone alternate-tuning diagrams, actual fret numbers are easiest to understand.

Step 4: Add the Chord Shape

Once the tuning is set, add the desired fretted notes.

For each string, choose one of the following:

Fretted note
Open string
Muted string
Unused string

Add the shape based on how the chord is actually played rather than how it resembles a standard-tuning chord.

Using the FretGlyph alternate-tuning chord creator, you can click the desired string and fret positions directly.

Step 5: Mark Every Open String Carefully

Open strings are especially important in alternate tunings.

Many alternate-tuning chords depend on drones and ringing open notes.

A single open string can determine whether the chord sounds:

Major
Minor
Suspended
Extended
Dissonant
Modal

Mark every intended open string with an O.

Do not leave the string status ambiguous.

Step 6: Mark Muted Strings

Not every open string in the tuning belongs in every chord.

A string may need to be muted because it:

Creates the wrong bass note
Conflicts with the chord quality
Produces unwanted dissonance
Makes the voicing too dense
Interferes with the melody

Mark muted strings with an X.

This is particularly important in open tunings, where strumming all six strings may automatically produce the tuning’s home chord.

Step 7: Add Barres

Open tunings often make barre chords easier.

In Open G, for example, barring several strings at one fret can create a major chord.

In Open D, a full barre can also produce a movable major chord.

When adding a barre, specify:

The fret
The first string covered
The last string covered
The finger used

Do not automatically extend a barre across strings that should remain open or muted.

FretGlyph can be used to create full and partial barres in alternate tunings.

Step 8: Calculate the Sounding Notes

Each note must be calculated from the tuning and fret position.

Every fret raises the open-string note by one semitone.

For example, if a string is tuned to D:

Open: D
First fret: Eb or D#
Second fret: E
Third fret: F
Fourth fret: F#
Fifth fret: G

This calculation applies to every string.

Automatic chord recognition depends on the accuracy of these pitch calculations.

Step 9: Review the Automatic Chord Name

Once the notes are entered, FretGlyph can analyze the voicing and suggest a chord name.

This is useful because alternate-tuning shapes are often difficult to identify by sight.

The application may consider:

All sounding notes
The bass note
Repeated notes
The selected tuning
Open strings
Capo position
Possible root notes

Review the suggested result rather than accepting it automatically.

Step 10: Check for Alternate Names

One alternate-tuning voicing may have several valid names.

For example, a group of notes could be interpreted as:

Dsus2
Asus4/D
D5(add9)
A chord with an omitted third

The best label depends on:

The progression
The melody
The intended root
The bass note
The musical style

A chord tool should provide useful suggestions while allowing the musician to choose the final name.

Step 11: Override the Name When Necessary

Manual naming is particularly important in alternate tunings.

A tool may correctly identify the notes but choose a name that does not match the chord’s musical function.

Override the name when:

Another root is intended
The chord functions differently in the progression
A simplified name is better for students
The voicing uses omitted notes
The diagram is part of a specific songwriting system
The preferred enharmonic spelling differs

Once the manual name is entered, it should remain unchanged until automatic naming is intentionally restored.

Step 12: Play the Chord

Use playback to verify the voicing.

Listen for:

Incorrect tuning
Wrong fret positions
Unwanted open strings
An unexpected bass note
Excessive dissonance
Notes that do not match the name

Playback is especially valuable in alternate tunings because familiar visual patterns may produce unfamiliar sounds.

You can compare the sound from FretGlyph with your guitar.

Step 13: Test the Shape on a Real Guitar

A digitally valid chord is not always physically comfortable.

Play the chord on the actual instrument and check:

Finger reach
String tension
Barre difficulty
Hand position
Accidental muting
Transition to nearby chords
Whether open strings ring clearly

Alternate tunings may change string tension, especially when several strings are lowered or raised.

A shape that looks practical on a diagram may feel different on the instrument.

Step 14: Add Finger Numbers

Finger numbers can help clarify unfamiliar shapes.

Use:

1 for index finger
2 for middle finger
3 for ring finger
4 for little finger
T for thumb when needed

Finger numbers are especially helpful for:

Students
Partial barres
Fingerstyle voicings
Large stretches
Shapes involving open strings
Chord transitions

Advanced players may prefer diagrams without finger numbers.

Step 15: Label the Tuning on the Diagram or Chart

Never publish an alternate-tuning chord diagram without identifying the tuning.

The tuning can appear:

Above the diagram
Below the title
In a chart header
In a caption
At the beginning of a book chapter
In a legend

Use the complete tuning rather than only the tuning name when possible.

For example:

Tuning: D A D G A D

This prevents confusion and makes the diagram usable outside its original context.

Creating Chord Diagrams in Drop D

Drop D is one of the easiest alternate tunings to work with because only the sixth string changes.

The tuning is:

Most standard chord shapes remain similar as long as the sixth string is muted.

The biggest changes occur when the sixth string is included.

Drop D Power Chords

The lowest three strings in Drop D are tuned:

At the same fret, these strings form a root, fifth, and octave.

This allows one-finger power chords.

To diagram a Drop D power chord:

Set the tuning to Drop D.
Place a barre across the sixth, fifth, and fourth strings.
Mute the upper strings when needed.
Label the chord according to the sixth-string root.
Add finger 1 to the barre.
Play the chord to confirm it.

At the fifth fret, this produces G5.

Drop D Open D Chords

The low open D can strengthen chords based on D.

A standard open D major shape can include the sixth string in Drop D, producing a fuller bass.

The diagram should show both the sixth and fourth strings as open.

Automatic naming should recognize D as the root rather than treating the low note as an inversion.

Creating Chord Diagrams in DADGAD

DADGAD tuning is:

The open strings create a suspended D-based sonority.

This tuning is well suited to:

Drones
Modal harmony
Celtic accompaniment
Fingerstyle arrangements
Open-string chord extensions

Naming DADGAD Chords

Chord names in DADGAD can be ambiguous because the open strings frequently add:

Suspensions
Ninths
Fourths
Fifths
Repeated roots

A shape that functions as G major may contain open A and D strings, creating a name such as:

Gadd9
Gsus2
G6/9 without a third
A slash-chord interpretation

Use the name that best matches the musical function.

Creating DADGAD Diagrams

When creating DADGAD diagrams:

Set all six open notes correctly.
Decide which drones should remain open.
Mute any open strings that conflict with the chord.
Review the bass note.
Check whether the third is present.
Listen to the playback.
Override the automatic name when necessary.

The absence of a third may make the chord harmonically flexible.

Creating Chord Diagrams in Open G

Open G tuning is commonly:

The open strings form G major.

A full barre across the appropriate strings can create movable major chords.

For example:

Open: G major
Fifth fret: C major
Seventh fret: D major
Twelfth fret: G major

Five-String Open G

Some players avoid the lowest D string and treat the fifth string as the primary bass.

This is common in certain rock and blues styles.

When creating the diagram:

Mark the sixth string muted if it should not sound.
Begin the chord from the fifth string.
Confirm the bass note.
Avoid assuming all six strings should be included.

Open G Slide Chords

Slide guitar often uses straight barres across several strings.

A diagram can show:

The fret
The strings played
Muted lower strings
Optional melody notes
The chord name

Playback can help confirm whether the voicing contains the desired root and chord quality.

Creating Chord Diagrams in Open D

Open D tuning is:

The open strings form D major.

A full barre creates movable major chords.

For example:

Open: D
Second fret: E
Third fret: F
Fifth fret: G
Seventh fret: A

Minor Chords in Open D

Because the open tuning contains a major third, minor chords often require changing or avoiding the F# string.

A minor voicing may need:

F natural instead of F#
The third string muted
A partial barre
A custom fingering

This is a good example of why each string must be marked accurately.

Creating Diagrams for Half-Step-Down Tuning

Half-step-down tuning is:

The visual chord shapes remain the same as standard tuning, but every chord sounds one semitone lower.

For example:

E shape sounds as Eb
A shape sounds as Ab
G shape sounds as Gb
D shape sounds as Db

A diagram may show:

Shape name
Sounding chord
Tuning

Decide whether the main chord label should represent the shape or actual sound.

For ensemble and publishing purposes, the sounding chord is usually more useful.

Creating Diagrams for Full-Step-Down Tuning

Full-step-down tuning lowers every string by two semitones:

Standard shapes sound one whole step lower.

For example:

E shape sounds as D
G shape sounds as F
C shape sounds as Bb
A shape sounds as G

Automatic chord naming should reflect the sounding notes.

Using a Capo with Alternate Tunings

A capo can be used in any tuning.

For example, Open D with a capo at the second fret produces Open E pitches while maintaining the lower string tension of Open D.

When using a capo:

Set the alternate tuning.
Enter the capo fret.
Build the chord shape.
Calculate the sounding notes.
Display both relative shape and sounding name when useful.

The order matters. The tuning is established first, and the capo raises every string from that starting point.

How to Organize Alternate-Tuning Chord Charts

A chart should clearly identify the tuning and organize related shapes.

Possible categories include:

Open chords
Major chords
Minor chords
Power chords
Suspended chords
Seventh chords
Movable barres
Song-specific voicings
Chords by root note

With FretGlyph, you can create up to 16 diagrams in one project.

Name projects clearly, such as:

DADGAD Chords in D
Open G Slide Shapes
Drop D Power Chords
Open D Song Voicings

Alternate-Tuning Charts for Guitar Teachers

Teachers should introduce alternate tunings with clear context.

A student chart might include:

The tuning
A string-by-string tuning guide
Three or four basic chords
Root-note locations
A short progression
Practice instructions
A reminder that standard chord shapes may sound different

Do not overload a beginner with too many unfamiliar shapes at once.

Alternate-Tuning Diagrams for Songwriters

Songwriters often use alternate tunings to discover new harmony.

A useful workflow is:

Choose a tuning.
Experiment with open strings.
Save interesting shapes in FretGlyph.
Listen to playback.
Review possible chord names.
Add manual labels when needed.
Arrange the shapes into a progression.
Export or save the project.

The diagram preserves the exact fingering, which may be difficult to remember later.

Alternate-Tuning Diagrams for Guitar Books

Authors should establish a consistent notation system.

Decide:

Where tuning labels appear
Whether chord names represent shapes or sounding harmony
How capo information is displayed
Whether note names or finger numbers are shown
How open drones are marked
Which enharmonic spellings are used

SVG export is usually the strongest choice for print because it remains sharp when resized.

Choosing Sharps or Flats

Alternate tunings may create chords that can be spelled in several ways.

For example:

F# or Gb
C# or Db
G# or Ab

Choose spellings based on:

The key
The root note
The progression
The book or project’s style guide

A progression in D major will usually use F# rather than Gb.

A progression in Eb major will usually use Ab rather than G#.

Common Alternate-Tuning Diagram Mistakes

Forgetting to change the tuning

This produces incorrect playback and chord names.

Entering the strings backward

Confirm whether the interface begins with the sixth or first string.

Leaving open strings active unintentionally

Alternate tunings often contain strong drone notes that can change the chord.

Using a standard-tuning chord name

The same shape may produce different notes.

Omitting the tuning label

The diagram may be impossible to interpret correctly.

Ignoring the bass note

A lowered string may create a slash chord or inversion.

Accepting the first automatic name without review

Alternate-tuning chords often have multiple valid interpretations.

Using impractical fingerings

Test every shape on a real guitar.

Forgetting capo transposition

Playback and naming must account for the capo.

How to Check an Alternate-Tuning Diagram

Before exporting, confirm:

The tuning is correct.
The string order is correct.
The capo position is correct.
The starting fret is visible.
Every fretted note is accurate.
Open strings are intentional.
Muted strings are marked.
Barres cover the correct strings.
The bass note is correct.
The chord name matches the musical context.
The fingering is playable.
Playback sounds correct.
The tuning is displayed with the diagram.
The export file is clear.

This checklist is especially important for published or educational materials.

Start Creating Chord Diagrams in Alternate Tunings

Accurate alternate-tuning chord diagrams begin with the correct open-string pitches.

Once the tuning is set, every fret, open string, bass note, chord name, and playback pitch can be calculated properly.

Mark all open and muted strings clearly, review automatic naming carefully, and use manual overrides when the musical context requires a different label.

Always identify the tuning alongside the diagram and test the shape on a real guitar before publishing it.

Whether you are documenting a songwriting idea, creating a lesson, preparing a guitar book, or building a personal chord library, FretGlyph can help you create, hear, organize, and export alternate-tuning chord diagrams.

Visit FretGlyph to create guitar chord diagrams in alternate tunings.

However, alternate tunings also make familiar chord diagrams less reliable.

That means a chord diagram for an alternate tuning must be built and labeled using the actual tuning of the strings.

What Is an Alternate Guitar Tuning?

An alternate tuning is any tuning that differs from standard guitar tuning.

Standard tuning, from the sixth string to the first string, is:

In an alternate tuning, one or more of those open-string pitches are changed.

For example, Drop D lowers the sixth string from E to D:

DADGAD changes several strings:

Open G is commonly tuned:

These changes affect every fret on the altered strings.

A note played at the third fret of the sixth string is G in standard tuning. If the sixth string is lowered to D, the third fret becomes F.

Because of this, chord recognition, playback, and labeling must all use the correct tuning.

Why Guitarists Use Alternate Tunings

Alternate tunings are popular because they can make certain sounds and techniques easier to achieve.

They may provide:

Lower bass notes
Easier power chords
Open-string drones
Rich suspended harmony
Easier slide-guitar shapes
Symmetrical chord patterns
Wider intervals
New songwriting ideas
Simpler fingerings
Different resonance

Alternate tunings appear in many styles, including:

Folk
Blues
Rock
Metal
Fingerstyle
Celtic music
Country
Ambient music
Experimental guitar
Singer-songwriter music

A tuning can influence the entire character of a composition.

Why Standard Chord Diagrams Do Not Always Work

A chord diagram shows string and fret positions, but those positions only produce the expected notes when the tuning is correct.

For example, a familiar E major shape assumes the sixth string is tuned to E.

If that string is lowered to D and still played open, the chord contains D instead of E in the bass.

The resulting chord may sound like:

E7/D
A different inversion
A suspended or extended voicing
A chord with an unintended bass note

The shape has not changed, but the harmony has.

This is why alternate-tuning chord diagrams should always identify the tuning clearly.

Common Alternate Guitar Tunings

Before creating diagrams, it helps to understand several widely used tunings.

Drop D

Drop D tuning is:

Only the sixth string changes.

Drop D is popular in rock, metal, folk, and fingerstyle guitar because it provides a low D bass note and allows one-finger power chords across the lowest three strings.

DADGAD

DADGAD tuning is:

It creates an open, suspended sound and is widely associated with Celtic, folk, acoustic, and fingerstyle guitar.

The open strings do not form a simple major or minor chord. They create a D-based suspended sonority.

Open G

A common Open G tuning is:

When all strings are played open, they form a G major chord.

Open G is popular in blues, slide guitar, roots rock, and certain rock rhythm styles.

Some players avoid or remove the lowest string because the open sixth string is D rather than G.

Open D

Open D tuning is:

The open strings form a D major chord.

This tuning works well for slide guitar, fingerstyle, folk, and open-string songwriting.

Open E

Open E tuning is:

The open strings form E major.

It produces higher string tension than standard tuning, so some guitarists prefer to use Open D with a capo at the second fret.

Double Drop D

Double Drop D tuning is:

Both E strings are lowered to D.

This creates strong D drones in both the bass and treble.

Half-Step Down

Half-step-down tuning is:

Every string is lowered by one semitone.

The visual chord shapes remain familiar, but every chord sounds one semitone lower than it would in standard tuning.

Full-Step Down

Full-step-down tuning is:

Every string is lowered by a whole step.

The shapes remain familiar, but the sounding chords are a full step lower.

Custom Tunings

Many guitarists create their own tunings.

A custom tuning may be designed around:

A song’s key
A particular drone note
A vocal range
A fingerstyle arrangement
Extended bass range
Symmetrical intervals
An unusual chord

A flexible chord diagram creator should allow each string pitch to be entered manually.

Step 1: Identify the Exact Tuning

Before building any chord diagram, write down the tuning from the sixth string to the first string.

For example:

D A D G A D

Do not rely only on a tuning name.

Different players sometimes use similar names for slightly different tunings. Writing all six notes eliminates ambiguity.

When using FretGlyph, select a preset tuning or enter each open-string pitch manually.

Step 2: Confirm the String Order

Always enter tuning notes in the correct order.

Most guitar tools list strings from:

Sixth string to first string

That means:

Lowest-pitched string first
Highest-pitched string last

However, some interfaces may display the first string first.

Confirm the order before continuing.

Entering the tuning backward will produce incorrect playback and chord names.

Step 3: Decide Whether the Diagram Shows Actual or Relative Frets

Most chord diagrams use actual fret numbers.

If a note appears at the third fret, the guitarist presses the third fret of the instrument.

However, capo-based diagrams may use positions relative to the capo.

For example, a diagram might treat the capo as a temporary nut and label the first fret above it as fret one.

Choose one system and explain it clearly.

For most standalone alternate-tuning diagrams, actual fret numbers are easiest to understand.

Step 4: Add the Chord Shape

Once the tuning is set, add the desired fretted notes.

For each string, choose one of the following:

Fretted note
Open string
Muted string
Unused string

Add the shape based on how the chord is actually played rather than how it resembles a standard-tuning chord.

Using the FretGlyph alternate-tuning chord creator, you can click the desired string and fret positions directly.

Step 5: Mark Every Open String Carefully

Open strings are especially important in alternate tunings.

Many alternate-tuning chords depend on drones and ringing open notes.

A single open string can determine whether the chord sounds:

Major
Minor
Suspended
Extended
Dissonant
Modal

Mark every intended open string with an O.

Do not leave the string status ambiguous.

Step 6: Mark Muted Strings

Not every open string in the tuning belongs in every chord.

A string may need to be muted because it:

Creates the wrong bass note
Conflicts with the chord quality
Produces unwanted dissonance
Makes the voicing too dense
Interferes with the melody

Mark muted strings with an X.

This is particularly important in open tunings, where strumming all six strings may automatically produce the tuning’s home chord.

Step 7: Add Barres

Open tunings often make barre chords easier.

In Open G, for example, barring several strings at one fret can create a major chord.

In Open D, a full barre can also produce a movable major chord.

When adding a barre, specify:

The fret
The first string covered
The last string covered
The finger used

Do not automatically extend a barre across strings that should remain open or muted.

FretGlyph can be used to create full and partial barres in alternate tunings.

Step 8: Calculate the Sounding Notes

Each note must be calculated from the tuning and fret position.

Every fret raises the open-string note by one semitone.

For example, if a string is tuned to D:

Open: D
First fret: Eb or D#
Second fret: E
Third fret: F
Fourth fret: F#
Fifth fret: G

This calculation applies to every string.

Automatic chord recognition depends on the accuracy of these pitch calculations.

Step 9: Review the Automatic Chord Name

Once the notes are entered, FretGlyph can analyze the voicing and suggest a chord name.

This is useful because alternate-tuning shapes are often difficult to identify by sight.

The application may consider:

All sounding notes
The bass note
Repeated notes
The selected tuning
Open strings
Capo position
Possible root notes

Review the suggested result rather than accepting it automatically.

Step 10: Check for Alternate Names

One alternate-tuning voicing may have several valid names.

For example, a group of notes could be interpreted as:

Dsus2
Asus4/D
D5(add9)
A chord with an omitted third

The best label depends on:

The progression
The melody
The intended root
The bass note
The musical style

A chord tool should provide useful suggestions while allowing the musician to choose the final name.

Step 11: Override the Name When Necessary

Manual naming is particularly important in alternate tunings.

A tool may correctly identify the notes but choose a name that does not match the chord’s musical function.

Override the name when:

Another root is intended
The chord functions differently in the progression
A simplified name is better for students
The voicing uses omitted notes
The diagram is part of a specific songwriting system
The preferred enharmonic spelling differs

Once the manual name is entered, it should remain unchanged until automatic naming is intentionally restored.

Step 12: Play the Chord

Use playback to verify the voicing.

Listen for:

Incorrect tuning
Wrong fret positions
Unwanted open strings
An unexpected bass note
Excessive dissonance
Notes that do not match the name

Playback is especially valuable in alternate tunings because familiar visual patterns may produce unfamiliar sounds.

You can compare the sound from FretGlyph with your guitar.

Step 13: Test the Shape on a Real Guitar

A digitally valid chord is not always physically comfortable.

Play the chord on the actual instrument and check:

Finger reach
String tension
Barre difficulty
Hand position
Accidental muting
Transition to nearby chords
Whether open strings ring clearly

Alternate tunings may change string tension, especially when several strings are lowered or raised.

A shape that looks practical on a diagram may feel different on the instrument.

Step 14: Add Finger Numbers

Finger numbers can help clarify unfamiliar shapes.

Use:

1 for index finger
2 for middle finger
3 for ring finger
4 for little finger
T for thumb when needed

Finger numbers are especially helpful for:

Students
Partial barres
Fingerstyle voicings
Large stretches
Shapes involving open strings
Chord transitions

Advanced players may prefer diagrams without finger numbers.

Step 15: Label the Tuning on the Diagram or Chart

Never publish an alternate-tuning chord diagram without identifying the tuning.

The tuning can appear:

Above the diagram
Below the title
In a chart header
In a caption
At the beginning of a book chapter
In a legend

Use the complete tuning rather than only the tuning name when possible.

For example:

Tuning: D A D G A D

This prevents confusion and makes the diagram usable outside its original context.

Creating Chord Diagrams in Drop D

Drop D is one of the easiest alternate tunings to work with because only the sixth string changes.

The tuning is:

Most standard chord shapes remain similar as long as the sixth string is muted.

The biggest changes occur when the sixth string is included.

Drop D Power Chords

The lowest three strings in Drop D are tuned:

At the same fret, these strings form a root, fifth, and octave.

This allows one-finger power chords.

To diagram a Drop D power chord:

Set the tuning to Drop D.
Place a barre across the sixth, fifth, and fourth strings.
Mute the upper strings when needed.
Label the chord according to the sixth-string root.
Add finger 1 to the barre.
Play the chord to confirm it.

At the fifth fret, this produces G5.

Drop D Open D Chords

The low open D can strengthen chords based on D.

A standard open D major shape can include the sixth string in Drop D, producing a fuller bass.

The diagram should show both the sixth and fourth strings as open.

Automatic naming should recognize D as the root rather than treating the low note as an inversion.

Creating Chord Diagrams in DADGAD

DADGAD tuning is:

The open strings create a suspended D-based sonority.

This tuning is well suited to:

Drones
Modal harmony
Celtic accompaniment
Fingerstyle arrangements
Open-string chord extensions

Naming DADGAD Chords

Chord names in DADGAD can be ambiguous because the open strings frequently add:

Suspensions
Ninths
Fourths
Fifths
Repeated roots

A shape that functions as G major may contain open A and D strings, creating a name such as:

Gadd9
Gsus2
G6/9 without a third
A slash-chord interpretation

Use the name that best matches the musical function.

Creating DADGAD Diagrams

When creating DADGAD diagrams:

Set all six open notes correctly.
Decide which drones should remain open.
Mute any open strings that conflict with the chord.
Review the bass note.
Check whether the third is present.
Listen to the playback.
Override the automatic name when necessary.

The absence of a third may make the chord harmonically flexible.

Creating Chord Diagrams in Open G

Open G tuning is commonly:

The open strings form G major.

A full barre across the appropriate strings can create movable major chords.

For example:

Open: G major
Fifth fret: C major
Seventh fret: D major
Twelfth fret: G major

Five-String Open G

Some players avoid the lowest D string and treat the fifth string as the primary bass.

This is common in certain rock and blues styles.

When creating the diagram:

Mark the sixth string muted if it should not sound.
Begin the chord from the fifth string.
Confirm the bass note.
Avoid assuming all six strings should be included.

Open G Slide Chords

Slide guitar often uses straight barres across several strings.

A diagram can show:

The fret
The strings played
Muted lower strings
Optional melody notes
The chord name

Playback can help confirm whether the voicing contains the desired root and chord quality.

Creating Chord Diagrams in Open D

Open D tuning is:

The open strings form D major.

A full barre creates movable major chords.

For example:

Open: D
Second fret: E
Third fret: F
Fifth fret: G
Seventh fret: A

Minor Chords in Open D

Because the open tuning contains a major third, minor chords often require changing or avoiding the F# string.

A minor voicing may need:

F natural instead of F#
The third string muted
A partial barre
A custom fingering

This is a good example of why each string must be marked accurately.

Creating Diagrams for Half-Step-Down Tuning

Half-step-down tuning is:

The visual chord shapes remain the same as standard tuning, but every chord sounds one semitone lower.

For example:

E shape sounds as Eb
A shape sounds as Ab
G shape sounds as Gb
D shape sounds as Db

A diagram may show:

Shape name
Sounding chord
Tuning

Decide whether the main chord label should represent the shape or actual sound.

For ensemble and publishing purposes, the sounding chord is usually more useful.

Creating Diagrams for Full-Step-Down Tuning

Full-step-down tuning lowers every string by two semitones:

Standard shapes sound one whole step lower.

For example:

E shape sounds as D
G shape sounds as F
C shape sounds as Bb
A shape sounds as G

Automatic chord naming should reflect the sounding notes.

Using a Capo with Alternate Tunings

A capo can be used in any tuning.

For example, Open D with a capo at the second fret produces Open E pitches while maintaining the lower string tension of Open D.

When using a capo:

Set the alternate tuning.
Enter the capo fret.
Build the chord shape.
Calculate the sounding notes.
Display both relative shape and sounding name when useful.

The order matters. The tuning is established first, and the capo raises every string from that starting point.

How to Organize Alternate-Tuning Chord Charts

A chart should clearly identify the tuning and organize related shapes.

Possible categories include:

Open chords
Major chords
Minor chords
Power chords
Suspended chords
Seventh chords
Movable barres
Song-specific voicings
Chords by root note

With FretGlyph, you can create up to 16 diagrams in one project.

Name projects clearly, such as:

DADGAD Chords in D
Open G Slide Shapes
Drop D Power Chords
Open D Song Voicings

Alternate-Tuning Charts for Guitar Teachers

Teachers should introduce alternate tunings with clear context.

A student chart might include:

The tuning
A string-by-string tuning guide
Three or four basic chords
Root-note locations
A short progression
Practice instructions
A reminder that standard chord shapes may sound different

Do not overload a beginner with too many unfamiliar shapes at once.

Alternate-Tuning Diagrams for Songwriters

Songwriters often use alternate tunings to discover new harmony.

A useful workflow is:

Choose a tuning.
Experiment with open strings.
Save interesting shapes in FretGlyph.
Listen to playback.
Review possible chord names.
Add manual labels when needed.
Arrange the shapes into a progression.
Export or save the project.

The diagram preserves the exact fingering, which may be difficult to remember later.

Alternate-Tuning Diagrams for Guitar Books

Authors should establish a consistent notation system.

Decide:

Where tuning labels appear
Whether chord names represent shapes or sounding harmony
How capo information is displayed
Whether note names or finger numbers are shown
How open drones are marked
Which enharmonic spellings are used

SVG export is usually the strongest choice for print because it remains sharp when resized.

Choosing Sharps or Flats

Alternate tunings may create chords that can be spelled in several ways.

For example:

F# or Gb
C# or Db
G# or Ab

Choose spellings based on:

The key
The root note
The progression
The book or project’s style guide

A progression in D major will usually use F# rather than Gb.

A progression in Eb major will usually use Ab rather than G#.

Common Alternate-Tuning Diagram Mistakes

Forgetting to change the tuning

This produces incorrect playback and chord names.

Entering the strings backward

Confirm whether the interface begins with the sixth or first string.

Leaving open strings active unintentionally

Alternate tunings often contain strong drone notes that can change the chord.

Using a standard-tuning chord name

The same shape may produce different notes.

Omitting the tuning label

The diagram may be impossible to interpret correctly.

Ignoring the bass note

A lowered string may create a slash chord or inversion.

Accepting the first automatic name without review

Alternate-tuning chords often have multiple valid interpretations.

Using impractical fingerings

Test every shape on a real guitar.

Forgetting capo transposition

Playback and naming must account for the capo.

How to Check an Alternate-Tuning Diagram

Before exporting, confirm:

The tuning is correct.
The string order is correct.
The capo position is correct.
The starting fret is visible.
Every fretted note is accurate.
Open strings are intentional.
Muted strings are marked.
Barres cover the correct strings.
The bass note is correct.
The chord name matches the musical context.
The fingering is playable.
Playback sounds correct.
The tuning is displayed with the diagram.
The export file is clear.

This checklist is especially important for published or educational materials.

Start Creating Chord Diagrams in Alternate Tunings

Accurate alternate-tuning chord diagrams begin with the correct open-string pitches.

Once the tuning is set, every fret, open string, bass note, chord name, and playback pitch can be calculated properly.

Mark all open and muted strings clearly, review automatic naming carefully, and use manual overrides when the musical context requires a different label.

Always identify the tuning alongside the diagram and test the shape on a real guitar before publishing it.
