I played alto for 4 years in high school marching band and I thought for college I would play tenor for marching band. I've played tenor before. Not excessively but I definitely know my way around a tenor and sounded pretty good. I read up on the mouthpiece I got (Rico Metalite MKM 9) and I thought it was a good choice for the money. I can barely make a sound out of it unless I'm blasting and then I can't usually go below like an E or Eflat. I don't think it's my horn that's the problem either. I don't want my section to think I'm incompetent. Should I try another mouthpiece? If so, which one? Thanks!
