Hellenic Orff-Schulwerk Association (E.S.M.A. CARL ORFF) is a non-profit association.

It was founded in Athens in November 1990 by the graduates of the first two professional training cycles in Orff music and movement education at the Moraitis School, as well as individuals actively engaged at the time in disseminating the ideas of Carl Orff’s pedagogical approach. Polyxeni Matey was named honorary president and the Matey School was designated as the place where the association is located.
