A solid, high quality mouthpiece. Personally on the tenor, I did find it to have a little bit of a thin sound when you are trying to push it to play louder music, but in any situation other than this it makes a beautiful tone, definitely most suitable for classical music in this tip opening. As with any other mouthpiece, a wider tip opening should definitely be considered for playing more contemporary music, and even for classical music I'd say it might be worth trying out something more like a D or an E opening with this particular mouthpiece.
