During the bridge improv, it reminded me of a spot in "L'isle Joyeuse" by Debussy. I don't know whether it's actually there or just something that I connected in my mind.
Great! I also used to play it in F, Db is interesting. But there is in fact some recording of Tom playing it in Db, I just don't know about what would be the "original" anyway. Ron, Have you heard about negative harmony? I was recently working on that subject in my course conclusion assignment and this was exactly one of the songs I chose! Other two were Giant steps and Autumn Leaves. The resulting is a really dark version of this bossa😂
Great lesson. The song sounds great without the cliche left hand rhythmic pattern. I never noticed the similarity to the "A Train" chord until you pointed it out. But those left hand 10ths in D flat....wow!
