de inciertos mares, y de tierra cierta.


('Habla un busto de Jano', La Rosa Profunda, Jorge Luis Borges)



In classical antiquity, the two-headed god symbolises beginnings and endings, duality, gates ...


Janus is a rhapsodic set of variations on a fixed harmonic configuration consisting of a group of seven notes and another of five, together adding to the total chromatic.  While the clarinet and the electronics, each alternate between these collections of notes continuously, between them they always unfold complementary groups. Unity in duality is further expressed in the layering, juxtaposition, and interweaving of  distinct, yet complementary, gestures, textures, and sonorities.


Janus was realised at the Electronic Music Studio of Glasgow University (directed by Stephen Arnold) using an EMS Synthi 100 treated through a variety of tape-delays and room reverberations. A digital version of the electronics (originally on magnetic tape) is available.
