I agree with you that there is no difference. I also do not use the chord scale theory as a basis for improvisation nor in my playing neither in my teaching, simply because I think good melodies are made of chord tones plus non-harmonic tones, and those can be either diatonic or cromatic ones. Not all notes of a melody need to be from the "chord scale". Also, there is no time in improvisation, specialy when chords change fast, to play a full scale for each chord; and picking up scale tones at random won't work either in building a good melody. >Avoiding the 7th in voicing the chord, leaving the choice of b7 or natural7 to >the improviser, how would that differ between the two chord designations? >Would someone really add a Bb or a Bnat to the A-7(b5)? I guess they could >add the 9th pretty easily, but so, too, could they add the Bb or Bnat in a >Cmin(maj6)/A designation, couldn't they, since the A would be in the bass and >thus farther away from where the Bb/Bnat would be voiced? This is what I think. Considering you have a Cm6 chord, you can choose either one of the 7ths in a melody. For instance if you play a descendig scalewise group of notes from D to A the Bb sounds good; and if you play a rising group from, say, C to Eb, the B natural will sound good also. As for the chord, you never use a b7 in a min6 chord, but you could add a Maj7th if the melody permits. For instance, if the melody is the root, you don't use the Maj7th, but if the melody is the 9th, the added Maj7h would soung good as in the chord C, A, Eb, G, B (rising from C) and a D in the melody.
