The Yanagisawa mouthpieces have been around a while are now considered a standard choice amongst many players. Yanagisawa produce just two different mouthpieces, an ebonite model and a metal model. These are very high quality mouthpieces and are made with the same Japanese-precision as their instruments.
The Yanagisawa ebonite mouthpieces feature a round chamber. This helps give the mouthpiece a smoother, thicker sound, which on the Soprano can be thin and harsh especially in the higher register. The sound is clear and precise which makes it ideal for classical playing. Tonally it has a fairly neutral sound which will help the player to develop their own sound. It does have some power, however it doesn’t have the projection as some other high-baffled pieces on the market. It is an excellent mouthpiece option for someone starting off on the Soprano, where your embouchure is adapting. It’s very user friendly and seems to be particularly suited to either classical music; or smooth jazz settings.
