I too have "gone back" with an emphasis on counting. I can play Sitting Easy Blues reasonably well most of the time. I can count it out loud and play it but when I bump up the tempo, not so much. The playing is there but not with counting out loud. Then again, some days I'll play it and it sounds like trash. I have moved on but still play/work on it daily.
Full out Blues is also coming along. There seems to be just a couple phrases that I don't get the count right. But I think I have it down enough to move on yet still practice it daily as well. I'm not sure if this moving on but continued practice is the right method or if I should be able to play it like I own it before moving on.
The swing feel counting seems to come and go with me. Usually I have no problem but then I'll have a day that I seem to want to play on all three sub beats instead of # - a. I am able to dial it in but still....
I seem to be taking quite some time to get the strumming lessons down. The strumming seems fine, unless of course I want to hit the C7 in time. LOL. I'm having difficulty hitting that chord. I may still move on to Muddy A Blues and continue with the previous tunes and 'strumming rests' practice for that C7.
I'm certainly willing to listen to suggestions on powering through.
Cheers,
Robb
