I have this mouthpiece for my alto, tenor and bari. I live by it! It shines above anything while also being able to play the soft solo jazz stuff. Couldn't recommend anything more highly to up the sound of you sax while also not completely breaking the bank like some other mouthpieces.
The Yani #5 metal mouthpiece gives great projection on a modern instrument. If used to a plastic or ebonite piece but you want a brighter, cleaner, more centred tone this could be it. The tip opening/side rail curvature creates added resistance, so a soft reed helps. The dynamic range and clarity helps you bring bring the instrument to life
