Esempio 1¶

Partendo da due scale differenti, creare un morphing tra le due per generare un profilo melodico. Creare l’armonizzazione delle due scale in maniera separata. Ad ogni ciclo di ripetizione della melodia prendere due accordi delle armonizzazioni e generare un morphing tra i due con diverse modalità, random, up, down e chiasmo.

[2]:

a = Scale.new(ScaleModel.dimWholeHalf, 60)
b = Scale.new(ScaleModel.bebop, 67)

chiasmoNote = a.morphing(b, 'chiasm')

chord_a = a.harmonize
chord_b = b.harmonize

chords = []

mode = ['rand', 'up', 'down', 'rand', 'up', 'chiasm', 'rand', 'down']
drop = ['drop2', 'drop3']*8

for i in enumerate(chiasmoNote):
    id = i[0]%8
    morphed = chord_a[id].morphing(chord_b[id], mode[id])[:-1]
    for c in morphed:
        bar_chord = getattr(c, drop[id % 2])
        chords.append(bar_chord)

seq_1 = PitchSequence((chiasmoNote)).out
seq_2 = PitchSequence((chords)).out

seq_1 = Staff(seq_1, 4, 90).out
seq_2 = Staff(seq_2, 2, 90, clef='bass', i_name='').out

Esempio 2¶

Partendo da una seire armonica, creare una modulazione ad anello con una frequenza modulante a scelta. Creare uno spartito con l’accordo della modulzione ad anello di durata 2 quarti e la scala ascendente in semitoni dell’accordo.
