So I have fallen into some (for me) uncharted musical territory. Im playing with Paul Desmonds Take Five. 1. Im playing AABA... Is this correct? 2. For the B section, IM trying to figure out the (not sure what its called) Cadence? Standard? Progression? Im playing in Eb- The B section im playing as... Bmaj7 Ab-6 | Bb-7 Eb-7 | Ab-7 Db7 | Gbmaj7 Bmaj7 Ab-6 | Bb-7 Eb-7 | Ab-7 Db7 | F-7 Bb-7 3. Is the following correct? IV iv | v i | iv VII | III IV iv | v i | iv VII | ii V I I recongnize the ii V I at the end but im a bit confused about the rest.... Can anyone shed some light on the subject?
