I've taken up studying with a cello teacher after toughing it out on my own for the past year and a half. (Shes's the only person that is close to a bass teacher within about 200km) She is a brilliant cellist and I was wondering if anybody had any advice for me/us? At the moment I am working on the grand march for aida and amazing grace for my exam, and am getting very frustrated technically. I know how the music should sound, but its really difficult for me to feel like I have 'mastered' anything. Some days I can play well and others it's like everything is impossible. Any advice?
