Determines whether the chord is a chord solfege

Determines whether the chord is a chord symbol

Normalizes the chord root and bass notes:

• Fab becomes Mi
• Dob becomes Si
• Si# becomes Do
• Mi# becomes Fa

Besides that it normalizes the suffix if normalizeSuffix is true. For example, sus2 becomes 2, sus4 becomes sus. All suffix normalizations can be found in src/normalize_mappings/suffix-mapping.txt.

When the chord is minor, bass notes are normalized off of the relative major of the root note. For example, Em/A# becomes Em/Bb.

Converts the chord to a chord solfege string, using the supplied key as a reference. For example, a numeric chord #4 with reference key E will return the chord solfege A#. When the chord is already a chord solfege, it will return a string version of the chord.

Converts the chord to a chord symbol, using the supplied key as a reference. For example, a numeric chord #4 with reference key E will return the chord symbol A#. When the chord is already a chord symbol, it will return a clone of the object.

Converts the chord to a chord symbol string, using the supplied key as a reference. For example, a numeric chord #4 with reference key E will return the chord symbol A#. When the chord is already a chord symbol, it will return a string version of the chord.

Converts the chord to a numeral chord, using the supplied key as a reference. For example, a chord symbol A# with reference key E will return the numeral chord #IV.

Converts the chord to a numeral chord string, using the supplied kye as a reference. For example, a chord symbol A# with reference key E will return the numeral chord #4.

Converts the chord to a numeric chord, using the supplied key as a reference. For example, a chord symbol A# with reference key E will return the numeric chord #4.

Converts the chord to a numeric chord string, using the supplied kye as a reference. For example, a chord symbol A# with reference key E will return the numeric chord #4.

Converts the chord to a string, eg Esus4/G# or 1sus4/#3

Transposes the chord by the specified number of semitones

Transposes the chord down by 1 semitone. Eg. A# becomes A, E becomes Eb

Transposes the chord up by 1 semitone. Eg. A becomes A#, Eb becomes E

Switches to the specified modifier

Tries to parse a chord string into a chord Any leading or trailing whitespace is removed first, so a chord like \n E/G# \r is valid.
