Schnebel composed several cycles of works, sometimes over a long time. One of them was called "Versuche" (Essays), consisting of four works written 1953 to 1956. They concern serial techniques, exploring space by placing performers at separate positions. His religious music includes a cycle "Für Stimmen (...missa est)" (For voices ...), consisting of four works written 1956 to 1969). They use the human voice and organ in experimental settings of prayers and biblical texts. A cycle "Produktionsprozesse" is a group of compositions related to "language and body" which concerns the physical sound production, with the performers utilizing speech and breathing organs in unusual ways.
