Hi, I am in my cities youth orchestra. There are 3 levels and I am at the second one. I want to move up to the third level. I am just starting to learn how to read trouble clef in thumb possition and just got my solo. As I'm looking at it near the end, it goes into tenor clef. Is that much different from bass clef? I am trying to learn this for march for solo and ensomble. How long will do you think this will take to learn? Thanks, Shae
