This happened in 1958. What about Charlie Parker? Did he miss these cornerstone of "jazz" concepts? Sure doesn't sound like it.

OK. Jazz musician or not, your in the Music Theory Section and I cant believe any schooled musician (or one who has taught at a university) would say that C major and A minor are the same when played over a chord progression. Of course a beginner would because they see the notes as being the same, but in theory there is a such thing as modes as well as melodic writting. How is it possible you have let go of this? It’s like a mathematician trying to tell me that numbers don’t exist. :rolleyes:

Take the example you used before; play the C major scale over the “A minor” chord progression: Amin - F - G. This is going to sound like it’s in the key of C. The C major scale over Amin is definitely going to lend to a modal (often confused with a minor tonality) sound. However the first chord, A min is just the substitute for C major chord. Check out the concept of “three principle triads” before you decide to argue with me, or the reason for the harmonic/melodic minor scales. Also, the key signature is decided by the melody not the harmony. The harmony job is to support the melody. This is the concept that gives away to modes.

"C6=(C,E,G,A)
Am/c=(A,C,E)
Nice try tough."

WRONG..... Am/C = (C,E,A,C,E) in open position. The symbol mean C in the bass.

C6= (C,E,A,C,E) in open position...... See?

HUH?? :confused: Open and closed position has nothing to do with inversions. Open and closed chords are determined by the interval from the bass note to the soprano note, which is either an octave less or more. Absolutely nothing to do with a chords spelling. The C6 formula is 1, 3, 5, 6. In your explanation of the C6 chord, there is no 5th (G). The C6 chord is the same as Am7/C. The reason for the chord ‘C6' is to name the chord (regardless of voicing) after the bass note.
