Python inversion Examples

Example #1

File: pcset.py Project: BrendanMoore42/midi_infinite

def prime_form(notes):
    set_zero = transposition_startswith(normal_form(notes), 0)
    set_inv = transposition_startswith(normal_form(inversion(set_zero)), 0)
    if interval_tie(set_zero) <= interval_tie(set_inv):
        return set_zero
    else:
        return set_inv

Example #2

File: pcset.py Project: Jbaud/pyknon

def prime_form(notes):
    set_zero = transposition_startswith(normal_form(notes), 0)
    set_inv = transposition_startswith(normal_form(inversion(set_zero)), 0)
    if interval_tie(set_zero) <= interval_tie(set_inv):
        return set_zero
    else:
        return set_inv

Example #3

File: test_simplemusic.py Project: suanchew/fhproject-music

 def test_inversion(self):
     n1 = [0, 4, 7]
     n2 = [0, 8, 5]
     n3 = music.inversion(n1, 0)
     self.assertEqual(n3, n2)
     self.assertEqual(music.inversion(n3), n1)

Example #4

File: test_simplemusic.py Project: Jbaud/pyknon

 def test_inversion(self):
     n1 = [0, 4, 7]
     n2 = [0, 8, 5]
     n3 = music.inversion(n1, 0)
     self.assertEqual(n3, n2)
     self.assertEqual(music.inversion(n3), n1)

Example #5

#!/usr/bin/env python

from pyknon.plot import plot2
from pyknon.simplemusic import inversion

n1 = [11, 10, 7]

for x in range(12):
    plot2(n1, inversion(n1, x), "ex-inversion-plot-{0:02}.ps".format(x))

n2 = [1, 3, 7, 9, 4]
plot2(n2, inversion(n2, 9), "ex-inversion-plot.ps")
