The Mr. P 4.8 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 4.8 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.
Mr. P highly recommends the Mr.P 4.8 for 3/4 and 4/4 BBb and CC tubas. The 4.8 is considered to be a medium-large diameter tuba mouthpiece with a Helleberg/funnel style cup. Mr. P has also designed a sharper rim for better flexibility and more overall weight for power.
Specifications: 33mm/1.3in inner diameter/medium large, deep 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.
Also available in small (American) shanks.
