Synaphaï was initially commissioned by Hofstra University on New York's Long Island for the conductor Eleazar de Carvalho and the pianist Jocy de Oliveira. It was finished in 1969 and premiered at the 1971 Royan Festival, of which he was a regular composer, during the festival's Xenakis Day, in which ten of Xenakis's most important works were performed. The piece was performed by Georges Pludermacher at the piano and the Orchestre Philharmonique de l'ORTF with Michel Tabachnik. The piece was later published by Éditions Salabert in May 1981.
