Symboles d'accords

A chord symbol is an abbreviated way of representing a musical chord and its harmony.

MuseScore Studio supports the following notations:

• Chord symbols: alphabetical chord name plus chord quality. e.g. 'Am'

• Roman numeral analysis (RNA): Roman numeral plus chord quality. e.g. 'vi'

• Nashville number system (NNS): Arabic numeral plus chord quality. e.g. '6m'.

Chord symbols

Chord symbols are mostly entered as plain text. As soon as you finish inputting or editing a chord (by moving to another chord, or by leaving edit mode), the characters are parsed and, as long as MuseScore Studio can understand the sequence, will be formatted correctly.

MuseScore uses this terminology for the parts of a chord symbol:

Entering chord symbols

1. Select a start note, note slash, or rest

2. Press Ctrl+K (Mac: Cmd+K); the cursor is now positioned above the staff ready for input

3. Type the chord symbol using this syntax:

   • root note: any letter a to g (case is not important)

   • accidentals: # (sharp), b (flat), x or ## (double sharp), bb (double flat)

   • for other symbols, extensions and modifiers, see Chord symbol syntax, below

4. To move the cursor forward to the next beat, note or rest (whichever comes first), press Space. For other ways to move the cursor, see Navigation commands

5. To leave the input mode, press Esc or click on an empty place in the score.

To enter an explicit natural after the root note, use the keyboard shortcut Ctrl+Shift+H (Mac:Cmd+Shift+H). Note that this will not play back, and the playback will be reduced to just the chord's root note.

To enter a space character within a chord symbol, use Ctrl+Space (Mac: Alt+Space).

Chord symbol syntax

MuseScore understands most of the standard abbreviations used in chord symbols, and will play them back accordingly. They can be input as follows:

• major: M, Ma, Maj, ma, maj, t (produces Δ; on Mac, ˆ also works)

• minor: m, mi, min, -

• diminished: dim, o (renders as ° if using the Jazz style; as o, the Greek omicron, otherwise)

• half-diminished: 0 (renders as ø if using the Jazz style; as 0 otherwise), or you can use abbreviations such as mi7b5 etc. Note: to get Dø, type D0, not Dm70 or Dm0

• augmented: aug, +

The following abbreviations are also accepted:

• extensions and modifiers, for example b9 or #5, sus, alt, and no3

• inversions and slash chords, for example C7/E

Finally, you can type parentheses, which can enclose any part of a chord symbol (or the whole thing), and commas.

Navigation commands

The following is a summary of keyboard shortcuts used to move the cursor in chord symbol entry mode:

Editing a chord symbol

Chord symbols are text items. Double-click on a chord symbol to enter edit mode (see Text editing). While editing, the chord symbol will be shown using text that follows the syntax described above. When you leave edit mode, it will again be converted to the correct formatting.

Roman numeral analysis

MuseScore Studio uses a specialist font (Campania) to provide the correct formatting for RNA. Unlike with chord symbols, when entering RNA using the syntax described below, the correct symbols and formatting will be shown with each keystroke.

Entering Roman numeral analysis

1. Select a start note

2. From the menu, select Add -> Text -> Roman numeral analysis (if you use this feature often, consider setting up a keyboard shortcut to do the same thing in Preferences)

3. Type the RNA symbols for the chord just like normal text, as follows:

   • major chord: upper case roman numerals (I, II, III, IV, etc.)

   • minor chord: lower case roman numerals (i, ii, iii, iv, etc.)

   • diminished chord: o (lower case)

   • half-diminished chord: 0

   • augmented chord: +

   • chord inversions: enter up to 3 single-digit numbers, top note first

   • accidentals: # (sharp), b (flat) or h (natural)

4. To move the cursor, the commands are the same as for chord symbols: see Navigation commands

5. To leave the input mode, press Esc or click on an empty place in the score.

While inputting, you can prevent any character from being interpreted by prefixing it with \ (backslash). This could be used, for example, to add the literal letters 'b' or 'h', or to input a non-superscripted number, etc.

Inversions can be indicated using the letters a, b, c, d by simply typing those letters.

For some more complex syntax, see the following examples.

Nashville number system

The Nashville Number System (NNS), is a shorthand method of representing chords by their scale degrees rather than chord letters. This allows an accompaniment to be played in any key from the same chord chart.

Entering Nashville numbers

To start entering Nashville notation:

1. Select a start note

2. From the menu, select Add -> Text -> Nashville number.

Just as with standard chord symbols, you can type Nashville notation normally and MuseScore will do its best to recognize and format the symbols appropriately.

The same navigation commands are used as for the other chord symbol types.

Chord symbol playback

To disable or re-enable playback of chord symbols entirely:

1. Click the cog at the right of the playback controls

2. In the menu, select Play chord symbols to remove or re-add the tick.

To disable or re-enable playback of a specific chord symbol:

1. Select the chord symbol

2. Allez sur le panneau Propriétés

3. In the General selection, check or uncheck the Play box.

Chord symbols style

The global style options for chord symbols are found in Format -> Style -> Chord symbols. Not every setting is applicable to every type of chord symbol notation; where not relevant, they will have no effect. (For example: switching to Jazz style will affect chord symbols and NNS, but not RNA.)

Each type of chord symbol notation does have its own default text style, which can be configured in Format -> Style -> Text styles (Chord symbol, Roman numeral analysis, Nashville number).

Appearance

Style

This determines how chord symbols are rendered. It affects all chord symbols in the score and cannot be overridden for a specific item.

• Standard: the default, where chords are rendered using the standard text font, with no additional formatting

• Jazz: the MuseJazz font is used for a handwritten look, with distinctive superscript and other special characteristics

• Custom: with this option you can customize the appearance of chord symbols by means of a chord symbols style file (in XML format, with extension .xml)

You can customise the scale for extensions and modifiers via Extension/Modifier scaling (as a proportion of the overall chord symbol size), and their vertical position via Extension/Modifier vertical offset (expressed in spaces).

Here are some example of how chords are rendered with different settings:

Spelling

The following options are available under Spelling:

• Standard: A, B♭, B, C, C♯... (this is the default)

• German: A, B♭, H, C, C♯...

• Full German: A, B, H, C, Cis...

• Solfeggio: Do, Do♯, Re♭, Re...

• French: Do, Do♯, Ré♭, Ré...

If Automatic capitalization is on (which it is by default), MuseScore will capitalize all the root notes of chords, regardless of whether they are entered in upper or lower case. You can disable this behaviour entirely by unchecking the box, in which case the capitalization will be left as you type it, or you can customise its behaviour via the options below:

• Lower case minor chords: minor chords will be made lower-case (major chords will still be capitalized)

• Lower case bass notes: bass notes will be made lower-case

• All caps note names: all letters in note names, not just the initial letter, will be capitalized (e.g. DO, RE, MI)

Positioning

• Distance to fretboard diagram: the distance between a chord symbol and a fretboard diagram below it

• Minimum chord spacing: the minimum horizontal distance between two chord symbols

• Maximum barline distance: (this used to control the distance between the last chord symbol in a measure and the following barline, but is now obsolete)

• Maximum shift above/below: the maximum distance a chord symbol can be moved up or down to align it with the preceding one on the system. If these are set to 0, the symbols will not align; to force all chord systems to align across the system, set this to a high value.

Playback

• Interpretation

  • Literal

  • Jazz: adds color tones (e.g. the major 9th) but may also omit certain notes - this depends both on the chord itself and its context, the next chord in particular

• Voicing

  • Automatic

  • Root only: just the bass note

  • Close: keeps the notes within the span of an octave

  • Drop two: lowers the second-highest note by one octave

  • Six note

  • Four note: 3rd, 5th, 7th and 9th intervals

  • Three note

• Duration

  • Until next chord symbol

  • Until end of measure

  • Chord/rest duration: following the duration of the chord or rest to which the symbol is attached, only

Regarding voicing, note that the triangle symbol (Δ) in MuseScore Studio creates a major triad only.

These options also affect how chords will be realized into notation; see Generating chord voicings onto a staff.

Capo fret position

MuseScore can create an extra bracketed chord symbol next to the main one for when playing with a capo; the bracketed symbol, when played using a capo at that position, sounds identical to the unbracketed one. (This feature only applies to chord symbols, not Nashville numbers or Roman numeral analysis.)

To enable this feature, set Capo fret position to a value above 0.

Chord symbol properties

In the Properties panel, in the Chord symbol section, you can change the playback settings for the currently selected chord(s), which will override the score-wide settings.

In the Text section you can override properties for the text formatting of the symbol, as for all other text items. (Note that the Font property will be ignored when the Jazz rendering style is used.)

Transposition

(See also the Transposition chapter.)

Transposing instruments

When switching Concert pitch on or off, chord symbols on transposing instruments will adjust automatically. When concert pitch is off and chord symbols are copy-pasted between transposing and non-transposing instruments, they will be transposed accordingly. Note, however, that chords associated with fretboard diagrams are not transposed automatically.

The Transpose dialog

The Transpose dialog (Tools -> Transpose) will transpose all selected chord symbols, though not Nashville numbers or Roman numeral analysis. To prevent chord symbols from being transposed, uncheck the Transpose chord symbols box in the dialog.

Generating chord voicings onto a staff

MuseScore allows you to generate notes from selected chord symbols and Nashville numbers (but not Roman numeral analysis) . The result will depend on the playback settings, described above.

To realize a selection of chord symbols:

1. Make a selection of chord symbols

2. Right-click on any chord in the selection

3. Click Realize chord symbols

4. In the Realize chord symbols dialog, if you wish to override the default options for the selection, check Override with custom options and configure the options below as necessary

5. Click OK.

External links

To change chord quality after Generating chord voicings onto a staff, use a plugin such as:

• Chord Level Selector

• Next inversion: replaces all chord(s) in (keyboard) selection with their next inversion

To identify harmony or chord, use a plugin such as:

• Chord Identifier (Pop & Jazz) for music that features harmonic chromaticism heavily, as the RNA created has jazz influence.

• Chord ID and Roman numeral analysis for music that features stable tonality, as conventional RNA are created.
