ClapocalypsE is an intermediate percussion ensemble for 5 Clappers, 1 Marimba, and 1 Vibraphone

Written with the modern style of rudimental bass drumming in mind, the performers of the clapping parts, or “Clappers," are required to play both split and unison patterns with great rhythmic clarity. The mallet parts are written for intermediate-level performers, perhaps individuals new to the four-mallet techniques.

Due to the unique instrumentation of the ensemble, it is recommended that the five clappers are at the front of the stage with the Marimba and Vibraphone directly behind them.
