George Katehis is a Greek-American composer who specializes in high-density and complex works for small chamber ensembles and solo instruments. His interests include early music and early/modern performance practice, polyphony, complexity, issues in music engraving, complex performance techniques and their praxis, and the preservation of rare and apocryphal 20th century and contemporary scores. More recently, his research has expanded to the Byzantine music tradition.
Katehis has taken lessons with Brian Ferneyhough, Claus-Steffen Mahnkopf, and Mark Andre, among others. Other instructors have included Joseph Downing in composition and tuning/temperamennt, Michael Calvert in early plucked strings, and Manos Georgandakis in Byzantine chant.
