Theory & Impro b13 and Charlie Parker

[cappers]

A video short by Jay Metcalf (Bettersax) popped up on my feed about a common lick CP used over a 2-5 progression.
Jay mentions that the key note in the phrase is the B flat leading to F# of D7 after the descending Am7. He calls this a b13.
I thought I was beginning to get some theory under my belt but this eludes me.
B is the 6th of D7 so why isn't it b6-3-2-b2 rather than b13-3-2-b2?
Thank you.

So if you are interested in learning theory it’s probably best to start off looking at the basics. We have done beginners theory and books here:

Reading through the entire thread, you've ingested way too much all at once. As Pete says, start with the basics and work up from there.
