Hi. I just got your book and it looks like you did a great job!
I was just reading thru the transcription of improv #1 and had a question about measure 71.
you've got 13 16th notes in a 3/4 measure with the tuplet sign "13:12" So I'm making a semieducated guess that means fit 13 16ths into the space of 12 (with feeling!)
I think I'll need to listen to Django playing that passage at halfspeed to get my head around that.
