The Clapper Trombone cap has the essential feature in any instrument of increasing the harmonic range thanks to the concomitance of the bells built- in the bottom caps.
This device greatly facilitates the dynamics of the trombone itself giving a greater volume to the harmonics, from note to note. With the Clapper bottom cap, we accomplish something essential for the players: dynamic COMFORT that widely eases the performance. The Clappers are always made in brass but the caps can be in brass or aluminum.
