Jan Maegaard, composer, musicologist, and well.known specialist in the music of Arnold Schoenberg, was one of the earliest exponents of the new music movement in Denmark in the 1950s. His output consists mainly of chamber music and reflects many of the most important trends in the development of the avant-garde, including dodecaphony, serialism, punctualism, open form, and most recently a return to a new kind of tonality.
