Psappha (Edition: Salabert, 1975) is a musical composition for multi-percussion solo by Greek modernist composer Iannis Xenakis. The work does not include specific instrumentation, although the composer calls for three groups of both wood and skins and three groups of metal instruments[1]. The actual printed performance score is written in a unique graph notation and consists of 2,390 segments and presents a greater demand on the performer due to this unique style.
