10.1.13.7. Temperament

This module defines temperaments.

class Musica.Theory.Temperament.EqualTemperament(number_of_steps, pitch_standard)

Bases: object

Class to define an Equal Temperament.

Step is an alias for semitone.

_compute_fundamental()

_compute_scale(octave, step_number)

fold_step_number(number, octave=False)

frequency(octave, step_number)

Return the frequency for an octave using the scientific pitch notation and an step number ranging from 0 to 11.

For A440 (La3), use octave 4 and step number 9.
