Description

BERP -- Buzz Extension & Resistance Piece for French Horn. According to the manufacturer, the buzz extension and resistance piece, better known as BERP, helps develop proper breath support by blowing into resistance, so  the player can buzz on the mouthpiece while holding the instrument in regular playing position. BERP also lets the player operate valves so as to match the pitches being buzzed, as a way of gaining ear-training benefits through reinforcing the connection between buzzing the mouthpiece and playing the instrument.
