Berp BERP5 Large Shank Trombone Buzz Extension Resistance Piece Tremolo and breath soundsThe buzz extension and resistance piece, better known as The Berp, helps you develop proper breath support by blowing into resistance, letting you buzz your mouthpiece while you hold your instrument in the regular playing position. The Berp also lets you press your instruments valves or move the slide to match the pitches youre buzzing, so you gain ear training benefits through reinforcing the connection between buzzing the mouthpiece and playing.
