I’ve been playing for around 6 months in my schools concert and now marching band. Before I was able to switch in the fall I played euphonium for around a year practicing daily and continue to practice euphonium for around an hour a day. I’m going to start practicing tuba daily as well, (for around an hour) and wanted to fix My tone because it sounds airy and just not as full as I want it to be. Any advice?
