Hello, Ed. Your making progress! You might try slowing down your count a bit. I know it feels slow but you sound rushed when I listened to you count aloud.
Also, I learned something new while watching you play!!!! I listened to your count and noticed you counted to six. I thought "wait its 3/4 time signature what is he doing???" I didn't notice the count notation in this piece! It was right under my nose...
I counted as follows (from the beginning): 3, 1 a & a, 2, 3. And so on. I'm not saying either method is "wrong" (note: large font represents string pluck).
If I cannot get a "feel" for tempo of a piece, or am repeatedly screwing up the piece, I've tried playing only (in this example) the quarter notes of the measure. So I skip the sixteenth notes until I can get some intuitive feel for tempo. You still play in 3/4, 6/8 time, etc.,, just with fewer notes. This sometimes works - just another way to simplify the piece and help "incrementally" learn. This is not a strategy for the Sor piece but might help with exercise #4
