Score Sample

Recording winter 2013 by Galen Dods, Lawrence University.

Orchestration: solo trombone

Duration: approx. 3 minutes


In Bichroma I challenged myself to use only two of the trombone’s slide positions as well as microtonal (notes not found in the equal tempered scale of the piano keyboard) slide positions directly above and bellow these main positions. Since microtonal adjustments of the slide are common practice on that instrument (for instance, to adjust for the flat 7th harmonic), I see microtonality in Bichroma as a natural extension of trombone idioms. The effect is poignantly reminiscent of that Romantic trope, the hunting horn.
