Application of the Major Pentatonic Scale on a Blues:
Whenever you think of playing pentatonic scales, it is easy, repetitive and familiar because it is such a short scale; But when we can apply them by creating a new sound on the chords, we can hear that new sounds are achieved with extensions and tentions.
(C, D, E, G, A) is something normal and familiar, but if we have a C7 # 9 chord and we play (Eb F G B C) we have a more interesting sound with this small scale applied on:
* C7 : C, D, E, G, A --- 1 2 3 5 6
* C7#9 : Eb, F, G, Bb, C --- 9#, 11, 5, b7, 1
* C11 : Bb, C, D, F, G --- b7, 1, 9, 11, 5
* C7#9 b13 : Ab, Bb, C, Eb, F --- 13b, 7b, 1, 9#, 11
* C7alt: Gb, Ab, Bb, Db, Eb --- 5b, 13b, 7b, 9b, 9#
