Two weeks from Thursday I was in pe my last class of the day and my sax was knocked down now the lower register isn’t coming out and every note in between third space c and a above the staff needs way more effort to play but I don’t see anything wrong with the saxophone it self I can get the notes to work going down but if I start at c every note but d will play and if I start on notes DEEbFF# with octave key they won’t come out without constant re try’s or adjusting my embouchure to get it playing and low F# down to low Bb needs a lot more air than usual does anyone have any suggestions
