librosa.display.ChromaSvaraFormatter

class librosa.display.ChromaSvaraFormatter(Sa=None, mela=None, abbr=True, unicode=True)

A formatter for chroma axes with svara instead of notes.

If mela is given, Carnatic svara names will be used. Otherwise, Hindustani svara names will be used. If Sa is not given, it will default to 0 (equivalent to C).

Parameters:

Safloat or None

The MIDI note number corresponding to Sa. If None, defaults to 0 (C).

melastr, int, or None

For Carnatic svara, the index or name of the melakarta raga. If None, Hindustani svara names are used.
