IV for Percussion Ensemble (Beyer, Johanna)
Instrumentation[edit]
The instrumentation of IV for Percussion Ensemble is not defined by Beyer in the score. Beyer leaves instrumentation to the choosing of the director. These playing sources are then amplified with surface microphones and manipulating using a mixing board.[1]
Analysis[edit]
The time signature is 7/8, and one player has an ostinato eighth-note rhythm controlling all tempo changes. This piece uses rhythms, dynamics, and accents to build structure, and shows an exposition, rise, climax, and resolution using pyramids of voices. The rhythmic structure of IV is complex because each time a rhythm repeats, another rhythm crosses it, and continues to add crossed rhythms until the midway point of the section, where the cross rhythms uncross themselves and repeats again, occurring a total of six times.[2]
