Practice Technique: Don’t look at the keys!
I'm sure its written. I'm sure you've heard it. Don't look at the keys!
Sure. But when the going gets tough, we look at the keys don't we?
I was practicing a line of McPartlands If You Could See Me Now (line 3 Page 46), which has a series of 10ths in the alternating bass line. Tenths are a stretch for me. In fact white key tenths are reached on the tips of the keys, above the key slip. So they are a challenge.
I found that though I practiced for hours, I really wasn't getting more consistent at striking the tenths confidently while playing at a good tempo. Then it dawned on me! I was constantly (twice per measure!) moving my eyes from the score to the keyboard. Something had to give. Either the score, or the keyboard. I'm of the opinion that ideally one should get to the point that vision is not essential to performance, so I chose to eliminate sight of the keyboard. (Hopefully the score will go away sometime, but that's another story)
To keep my eyes from the keyboard, I wedged three music books between the music desk and the fallboard, so that I was playing with my hands below the books, while I was referencing the score above the books. It really worked! I found that while my vision of the keys was eliminated, my initial performance was no worse than with full sight. Interesting. As I practiced, I found that my accuracy improved. More later ... The quest for excellence continues.
