construct_notename

pitchtools.construct_notename(octave, letter, alter, cents, freqdev=0, normalize=False)[source]

Utility function to construct a valid notename

Parameters:

  • octave (int) – the octave of the notename (4 = central octave)

  • letter (str) – the pitch letter, one of “a”, “b”, “c”, … (case is not important)

  • alter (int | str) – 1 for sharp, -1 for flat, 0 for natural. An alteration as str is also possible. alter should not be microtonal, any microtonal deviation must be set via the cents param)

  • cents (int) – cents deviation from chromatic pitch

  • normalize – if True, normalize/check the resulting notename (see normalize_notename())

  • freqdev (int) – frequency deviation from the given pitch (in Hz)

Return type:

str
