Rituel in memoriam Bruno Maderna (1974–75) is a composition for orchestra in eight groups by Pierre Boulez. Biographer Dominique Jameux wrote that the piece has "obvious audience appeal", and that it represented a desire to establish "immediate, almost physical contact with the public". Jameux also noted that Rituel represents one of the few examples of repetitive music written by Boulez. Author Jonathan Goldman wrote that, of Boulez's works, Rituel is the one that "most evokes... the sound worlds of non-Western musical ensembles, be they Indonesian, African or South American."
