The Mr. P 6.4 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 6.4 works very well with F and Eb tubas because of its relatively shallow, bowl shaped cup. Tuba players with large bore F and Eb tubas will find that the 6.4 helps with a more consistent response and evenness throughout the range of the instrument. Mr. P has also designed a sharper rim for better flexibility and more overall weight for power.
Specifications: 32mm/1.26in inner diameter/moderately shallow cup
Depending on inventory levels, the Mr. P mouthpiece you receive may be labeled "Mr. P Signature - Potenza Music". This model is exactly the same as "Liberation" but has the former distributor's label.
