As I’ve posted elsewhere, I’m picking up clawhammer banjo, and have been at it about 2-3 days. As someone who’s played Scruggs-style for a long time, it’s similar but different. That is, the left-hand fingerboard stuff is familiar (although that’s not my focus right now), the right-hand (picking) stuff is wildly new.
An online video I found said something interesting. To paraphrase, “muscle memory learning happens while we sleep.”
I was skeptical, but after a day or two of practicing a completely new right-hand technique, maybe it does! Two days ago, I was trying to hit individual strings with my middle fingernail in a hammer motion, and was completely unable to. Today, I kinda can! Not perfectly, but there was definite improvement.
Do others, on other instruments, find they improve “overnight”?
