the pentatonic scale or the Maj 6/9 chord for
N
=4
the diatonic scale for
N
=6
the chromatic scale for
N
=11
These scales have an increasing harmonic complexity. Scales of different
complexities can also be generated by varying
V
: Let
V
= (4) and
N
= 2, we then
generate a pitch scale corresponding to an augmented chord. Let
V
= (3) and
N
=3,
we then generate a pitch scale corresponding to a diminuated chord. Let
V
= (3, 4,
4, 3) and
N
= 6, we then generate the ascending melodic minor scale.
11.3.4.2 Chords Sequences
In MuZICO, the chords sequences are generated by a grammar that takes the
context into account to oversee the transpositions related to the modulations. The
complexity of a chord depends on several factors that we identi
ed:
the number of notes that make it up
the complexity of the scale on which it is built
the order of appearance of its notes in the building of this scale by iterations
The complexity of a chords sequence also depends on several factors:
the complexity of the chords that make it up
