Peter-Jan Wagemans (The Hague, September 7, 1952) is a Dutch composer. Wagemans studied organ (diploma 1974), composition with (diploma 1975) and music theory (diploma 1977) at the Royal Conservatory of The Hague. After his studies he also worked with Klaus Huber in Freiburg. According to Wagemans' philosophy, music is shaped in the observation of the listener. Therefore, Wagemans tries to focus on ways a work can be recognised, rather than on its fundamental structure. He generally makes use of what he prefers to call musical archetypes, unifying ambivalent elements.
