a program i'm making (yes that one) will benefit from knowing about
musical scales. i looked in the source code for non-sequencer (i'll
look at arpage next), and adapted an array there into the following
form:
{ "Major", { 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1 }},
{ "Natural Minor", { 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 1, 0 }},
{ "Harmonic Minor", { 1, 0, 1, 1, 0, 1, 0, 1, 1, 0, 0, 1 }},
{ "Melodic Minor", { 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 0, 1 }},
{ "Major Pentatonic", { 1, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0 }},
{ "Minor Pentatonic", { 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0 }},
{ "Chromatic", { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 }}
(1 means a note is part of that scale, 0 means it is not).
so for C Major:
{ "Major", { 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1 }},
c c# d d# e f f# g g# a a# b
(Unless I'm mistaken) all the above scales can be transposed to work
with any key.
Now I'm not very musical, and found my way to wikipedia, specifically this page:
http://en.wikipedia.org/wiki/Whole_tone_scale
Which says "In music, a whole tone scale is a scale in which each note
is separated from its neighbours by the interval of a whole step.
There are only two complementary whole tone scales, both six-note or
hexatonic scales:
* {C, D, E, F♯, G♯, A♯, C}
* {B, D♭, E♭, F, G, A, B}.
"
Which is confusing for me because it seems I can represent it in the array as:
{ "Whole Tone", { 1, 0, 1, 0, 1 ,0, 1, 0, 1, 0, 1, 0 }},
But goes on to say I it is impossible for any key other than "c" or
"b" but the array representation seems to show it could work for any
key.
Can anyone explain?
Cheers,
James.
