Boy was I glad to read the comments in this thread. I thought aliens were messing with my memory bank! I just discovered at a jam that a tune I thought I had down pat (Jackie Tar) had a "missing" part. It also seems lately that every tune I try to learn has a "hard" part the fingers & mind just won't grab. Since I don't read music I usually just isolate the series of notes and try to work on them slowly. I heard an interesting quote the other day from a fiddler (which I may have related somewhere else in Mudcat): "If you don't practice for one day, you can hear it. If you don't practice for two days, other fiddlers can hear it. If you don't practice for three days, the audience can hear it!" I really appreciated Praise's insight on how to deal with these problems.
