KeySignatureType (Enum)

Common key signatures.

Key signatures are specified as dicts between the 7 pitch letter names and either an AccidentalType or None. They are enumerated here in the form [pitch letter][f|s]_[major|minor]. For example:

  • c major is KeySignatureType.c_major
  • f-sharp minor is KeySignatureType.fs_minor
  • d-flat major is KeySignature.df_major
This enum defines the entire circle of fifths - from 0 flats to 7, and 0 sharps to 7.
