Yeah confirmation is a tough tune. Anyone can learn those solos up to speed, but analysing the song is different. What I'm saying is, the solo has to be understood in the context of the key changes and Jazz music, bebop onwards, isn't the best music to start off with when learning about basic harmony. When I say learning, I mean learning to hear relatively,
I don't really care about fancy scalar/harmonic names. A 3rd in a key is a 3rd, and you hear it that way. Being able to hear relatively also means being able to transpose quickly.
