So, we've got a handle on major & minor scales/modes/chords. Cool.
Bebop scales are an invention by (duh) the beboppers...and here's why: The whole thing of bop is 'running changes'. Up, down, left, right - arpeggios, guide tones, alterations and extensions, tri-tone subs...it's all just running changes. Now, when you see a Dominant chord, and should you choose to play the descending mixolydian mode, it doesn't line up properly.
[I don't have access to finale & internet at the same time...so we're lacking visual aids this time]
8th notes being the boppers choice:
Code:
C Bb A G F E D C
1 + 2 + 3 + 4 +
See?! All the strong beats have non-chord tones on them. Sucky! By Adding a single quick passing note, we can fix this.
Code:
C B Bb A G F E D C
1 + 2 + 3 + 4 + 1
Nice!!
Going down is when the coolness is so apparent. Either way, the extra note plops the root right down on 1 of the next bar, setting you up nicely for the next chord.
Bebop Dominant: C D E F G A Bb [ B] C
Bebop Dorian: C D Eb [E] F G A Bb C
Bebop Major: C D E F G [Ab] A B C
The added notes are simply to help it flow better and shouldn't really sound or be accented...
