Hi.
I first have to tell you that I am a beginner.
I was practicing to get better, I took a little break for some minutes, and as I began playing again it didn't sounds right. Everything was one octave higher than it should be. I'm pretty sure that I place my mouth correctly (but I'm a beginner so…). I've tried different reeds, and if I only use the mouthpiece it sounds correct but the saxophone plays one octave higher that it should.
Do you have any solution?
