The Mr. P 6.3 tuba mouthpiece by Liberation is designed by Daniel Perantoni, Professor of Music at the distinguished Jacobs School of Music at Indiana University. Also known as Mr. P, Perantoni has been in the mouthpiece business for several decades and the 6.4 is the modern version of an earlier very successful design. The Mr. P Signature tuba mouthpieces have been engineered for better response, ease of playability, and a centered, focused sound.
The Mr. P 6.3 is a shallow, bowl mouthpiece that is suited very well for the high range. Tuba players that are met with the challenging demands of the modern solo repertoire will find the 6.3 to be a valuable tool. The sharper rim provides a quick, bright response with fantastic flexibility.
