 It quickly became the most frequently played solo percussion work, and "inspired a wave of writing for percussion" .The work is written for one percussionist playing a marimba, vibraphone (motor off), 4 tom-toms, snare drum, güiro (one or several, if necessary), 2 African log drums (each producing 2 pitches), 2 suspended cymbals of differing sizes, hi-hat, 4 almglocken (suspended, clappers removed), a suspended "bunch of bells" (preferably Indian bells or tambourine mounted on a stand), at least 2 high pitched triangles, gong (with raised boss in center) and tam-tam.The title of "Zyklus" is reflected in its form, which is circular and without a set starting point.
