jc3000

A small python package for generating music. Inspired by this which was inspired by this (that's why it's called jc3000).

You can generate any notes you want based on any fundamental (the frequency of concert A in this case, fundamental as a term is used kind of loosely). You can also use either just or equal temperament.

More reading

This page has really good information on how music and scales work at the physical level.

Default sample rate is 44,100 Hz.
Default concert A is 440 Hz.

Installation

You can install it via pip. It requires numpy. Probably not compatible with python <= 3.6.

python3 -m pip install jc3000

Examples

• Play the licc

from jc3000 import Sequence

s = Sequence(fs=44100, fundamental=440, equal=True)
s.add_note('d', duration=.125)
s.add_note('e', .125)
s.add_note('f', .125)
s.add_note('g', .125)
s.add_note('e', .257)  # .257 for ~swing-iness~
s.add_note('c', .125)
s.add_note('d', .25)

s.write_file('the_licc.wav')

• Play the C major scale with concert A set to 432 Hz.

from jc3000 import Sequence

s = Sequence(fundamental=432)

notes = ['cdefgabc']

for i, note in enumerate(notes):
    if i < 5:
        s.add_note(note)
    else:
        s.add_note(note, octave=1)
        
s.write_file('cmajor_432hz.wav')
