I'm primarily a folk musician, been playing many years. Recently, aged 55 started classical guitar got to grade 5. Hence I think I can learn some stuff with some level of precision.
Now I'm trying to improve the folk side of things, trying to work some instructional DVDs - currently trying Al Pettaway's Celtic Guitar. I'm hitting a problem that I've hit before: when trying to learn a new rhythm pattern, even when it seems on the surface pretty simple, I seem to revert to some simpler pattern I already know. It stays in time but it's not the pattern being taught. I've tried using the learning techniques I used in the classical world, play a small section very slowly, until I can play it reliably, then speed up.
In this case I'm only trying to learn a single bar and I am really struggling, a couple of repetitions and suddenly I'm sliding back to something else.
Any tricks, or other approaches, or is it just keep on working?
