Yamaha 4C Tenor Saxophone Mouthpiece If you are looking for an afforable, high quality mouthpiece for your instrument, look no further! Yamaha mouthpieces contribute to the high regard that Yamaha has earned among beginning and professional musicians alike. The result of a special approach to design and manufacture, Yamaha mouthpieces deliver the performance and comfort required where they are needed most: where instrument meets musician.  This tenor saxophone mouthpiece is in a 6C facing, and is more open than the standard 4C. This mouthpiece would be desired by an advancing or professional musician who is capable of handling the wider opening.  If you are unsure which facing is best for you please inquire!!! We always recommend viewing a mouthpiece comparison chart and to discuss with an instructor/educator which opening they'd recommend based on your needs.
