You know, I wish I could tell you.
It worked fine when I got it and I came back after the summer and it packed in. I took it to get sorted and apparently the key had moved slightly out of place [only cost £2.50 to get fixed, I was chuffed to bits]. I think it's probably half psychological because on my old clarinet it was impossible to play and my teacher at the time told me it was my inability [though she refused to check herself], so I have a hatred of that note [and the teacher].
It's not actually my clarinet. It's a county one, so taking it apart probably wouldn't go down well with them. I'm begging my parents to buy me my own though.
