He has also written extensively about the evolution of the Mediterranean learned musical tradition and its relationship to contemporary music. His publications include The Oud - Teaching Method (1996) and Post-Byzantine Music Manuscripts as a Source for Oriental Secular Music (15th to Early 19th century) (2012).
