just checkin, ,mark, you are saying that you have your normally the 7th chord of c ionion would be (i dont know the name) root(B), minor3 (D), diminishd 5th (F), minor 7th (A).
but we play the dimminished scale with the bb7 (Ab). so this clashes with the chord and the key. but it doesnt clash so much that tonality is lost. so tension is built up.
is this right.
so when u use this do you try and resolve the Ab to an A as u play or do u just plow ahead with a diminished scale, letting the b7 and bb7 clash. is it a bit like playing a minor third over a 7th chord in a 12 bar blues?
