I've done that, but I did notice something kind of important... I did that when I had a particularly challenging measure or 2. I would skip over them, get to the end and use that to motivate me. I'd then go back and do my little "micro-focus" session by seeing nothing but that 1-2 measures and get it down before going back to the beginning. It is not something that I did on every song, just the ones that were particularly irksome in a few measures.There is always the temptation to reach the end of a piece because it’s fun,but that’s a waste of time. I think my lessons today are more about learning how to practice when my teacher is not by my side.
I noticed that in *some* cases, that actually helped me get through the song faster.
I've come to realize that down inside, I have a true love/hate relationship with learning. I absolutely hate the process of learning something new, but I absolutely love adding something new to my head.
