The BERP BERP4 Buzz Extension Resistance Piece is a practice tool designed for small shank trombone players who want to work on buzzing, airflow, pitch center, and embouchure control while using their own mouthpiece. It attaches to the instrument's mouthpiece receiver, allowing players to buzz with resistance that more closely resembles playing the trombone.
This is a useful accessory for warmups, private lessons, marching band, sectionals, and focused practice away from the full instrument. Students and advancing players can use it to build better air support and consistency, while teachers often use BERPs to help players connect mouthpiece work directly to instrument playing.
