I have an amazing teacher. You can see for yourself at nancello.com. She encourages me beyond my abilities and makes me believe I can do anything. So I continue to try everything. I’m playing in a community orchestra and a new cellist joined me. She is young and started playing cello as a child. Needless to say, she is an excellent cellist. She didn’t have any music so she was reading off mine. I had to explain it to her, as it is full of markings. Numbers, shift markings, colors, notated repeat info. At the next rehearsal she had her own music with nary a mark. I admit, most people do not make as many marks as I do, but as a late learner, I need more help. It’s not obvious to me when to shift and I have a hard time looking ahead. Bad eyes or just less practice, or a combination. But since I’m doing this for my pleasure it makes sense to me to do whatever it takes for me to do the best I can do. So I encourage you to do the same. Mark up your music if it makes it easier for you. Use colors and special marks that you understand. I did notice that my new cellist stand partner was quickly marking the repeats on the music, just before we played. So maybe all my ideas weren’t so bad.
