I’ve been playing with the David Baker “How To Play Bebop” patterns. I noticed you said when you have a chord tone with the first finger, and you want to play the lower neighbor (chromatic) and back again that you prefer to do it as “1st finger – 4th finger stretch – 1st finger” as opposed to “1st finger – slide down with 1st finger – slide back up with 1st finger.”
I’ve tried both methods and I always feel the 2nd version (sliding with 1st finger) always sounds smoother and more natural sounding to me.
How do you feel about that?
