Portulan: an ancient maritime atlas that showed coastlines and indicated principal landmarks to sailors still lacking compas- ses. Portulan, a chamber music project that should, upon completion, consist of a cycle of nine or ten pieces. It will be writ- ten for eight musicians (flute, clarinet, horn, piano, percussion, violin, viola and cello), but each piece uses a different com- bination within that ensemble. It is also a sort of autobiography through metaphors, in the sense that each piece refers to something, place, trip, reading or aesthet- ic experience of particular significance for me. In addition, Portulan is the title of a po- etry album written by Murail\'s father that was important to him when he was an adolescent.
