I just got hold of the 2006 Kurt Rosenwinkel transcriptions book and I'm looking through some of the lead sheets and getting confused by some chord symbols.
For example the chords for the first 8 bars for 'The Cloister' (after the drums & piano intro) are:
Ami7 - A/C7(b9) - Db/G - F#/C - F#7sus - Ami7(b6) - CMaj7 - CMaj7
What does an A over a C7(b9) mean? From my (limited) knowledge the something/something notation is used to indicated a particular inversion by specifying the bass note. But here we have full chords!
Does that mean a C7(b9) with an A triad? So essentially a C7(b9)13?
It's also worth mentioning that in some other tunes ('Brooklyn Sometimes' for example) he also uses chords like CMaj7/D so we can have chords both over and under?
Any tips appreciated, thank you!
