Filiforms result from a type of metal corrosion. Though their delicate blue-green and brownish filaments are very visible, they have no weakening effect on the metallic substrate. The work also describe minutely etched lines found in ancient rock carvings.

At the heart of Filiforms is an 8-channel, speaker-point diffusion concept. The piece extends my interests in composing with dense textures and complex timbres. I use 8 channels (and normally 8 loudspeakers) in this piece to achieve clarity and rarefaction of the overall sounds, and to allow control and articulation of slowly changing detail. The sounds’ identities are thus striated in three-dimensional space. They are designed to interact toward a sum result in space that is dislocated from individual point sources. In occasional sections of the piece, however, the loudspeaker locations do serve as loci of discrete sound movement and exchange. Still, no single, or forward facing, listener point of view is favored; and a circular diffusion space surrounding all listeners is the ideal formation.


Filiforms was realized in 2004 at the composer’s studio in New York City (NY, USA) and premiered in its original 8-channel version on September 23, 2004 at the Harvest Moon Festival 1 at Concordia University (Montréal, Québec).
