I have a Yamaha 23, and by mistake I grabbed my tenor mouthpiece (it had been a long day. ha ha). The sound was GREAT!! Now, I'm wondering how I can get that same deep jazzy sound in an alto mouthpiece. I can't even find a brand on the tenor mouthpiece. It's from my old 1970's Yamaha 61. The sound of that mouthpiece is amazing compared to the Yamaha 4C that's on my 23...and it's even easier to play. Much smoother. I was using a size 2 reed. Any ideas what could give me that deep mellow sound almost like a bright tenor rather than an alto? Thanks!!
