Dear Jeff,
Thank you so very much for such a comprehensive and encouraging response, I really appreciate that!
Of course, I messed up the fingers' number: I meant 2, 3, and 4. But you recommend 1, 2 and 4, and I will try that.
One more question about strumming: do I try to make a "shaking" move with the wrist? Also-do I try to strum all the strings in the chord. It's just the high E doesn't sound good when strumming the G chord. Unless my tuning is off, I will check this out.
Again, thank you so very much, you are very kind.
