Hi so I’ve been playing flute since middle school as well as some in high school. I stoped for a few years and decided I want to play for my university in symphonic band. I bought a decent flute off of Amazon and I for some reason am struggling playing e flat and f. I noticed that the small thumb key is sometimes pressing down it seems loose. I don’t know how to fix it. But I do know my f and e flat are coming out sharp or not at all.
