For those contributing tracks to Cosines and Tangents, music is a more precise way to communicate. This volume, the third in the Tone Science series, presents nine works - every one made using a unique modular synthesizer system. Each component within these cases and cabinets is a discrete part chosen and arranged according to the taste and direction of the individual artist. Filters, oscillators, mixers, ring modulators, envelopes, and other even more esoteric pieces provide an unprecedented flexibility in sound design and music making. They are systems that are not fixed in the way conventional instruments are, and attract an interesting mix of musicians and engineers. Represented on Cosines and Tangents are a compelling cross-section of talented people from out of this body. From the raw power of Berserker by Redshift, to the intellectual vigor of Cyclosporum by Robert Rich, then down to the unpeopled space of En-Edge by Radek Rudnicki, on up to the gentle mental popping pulse of Round #2 by Benge, this collection, in turns, offers the feeling of coming home, followed by the sense of leaving Earth. Overtly synthetic, these realizations all confer a particular electrical power - in hopes of awakening possibility in listeners. As there is no one perfect way to perform this music, we are well served by the select imaginations uplifting this group. Threading between the forces of chaos and order Cosines and Tangents produces a fascinating energy - a trait which has yet to be fully explained. However, what may be explained is why the field of Electronic Music has over these many years remained so innovative, so ahead of its time. This is plainly so because its practitioners have not forgotten the first principle of their work... the expressive manipulation of timbre - and remained true to a faith... that just as the soul animates a person, so timbre animates a sound.
