Jan Rokus van Roosendael sought from the beginning an individual idiom that allowed him to express his leaning toward reflection and the spiritual. He initially found inspiration in non-Western music, reflected principally in cyclical musical structures. In his later work, from Windows (1996), his quest for a “new euphony” (that is, a return to pre-avant-gardist tonality) led him to Renaissance polyphony, a development nipped in the bud by his premature death.
