This is excellent. I have not heard any guitar teacher explain this even though I've had four! The idea of playing without mistakes is bandied about a lot but this shows very clearly what it really means. I wii certainly use it when I start my next piece. Do you think it's worth using it a piece that's almost learned without this kind of precision or is it best to start completely fresh?
Thanks bertaga41, You can use this method to troubleshoot tricky spots, learn new pieces, or do it with memorized pieces to test your memory. Whatever works, really. Thanks again! Cheers, Allen
