Lois V Vierk

for six trumpets

 

Cirrus (1988) is a work for virtuoso trumpet players. It unfolds slowly and is directional and developmental. The work begins on one pitch in the trumpet's middle register, a held tone with crescendo and decrescendo. Very soon a punctuating 16th note is added at the top of the crescendo, and soon after that a slow glissando (played with the trumpet slide) is added to the phrase. These are the materials that are developed for the rest of the piece. Pitches are added to the phrase. The register expands as does the dynamic range. The 16th note figure is developed, first alternating between two pitches at a time and creating rhythmical phrases, and eventually becoming scalar passages. These passages get longer and longer, eventually moving up to the high register of the instrument, at the loudest and most articulated and fastest moving part of the piece, the climactic section. Then the scalar passages reverse their direction, coming down to the lowest register, where the glissando material has become faster, alternating back and forth between two tones. The scalar passages become shorter, dying out as the glissando again slows down. The work ends lyrically, reminding me of graceful cirrus clouds.

This is one of my pieces for ensembles of like-instruments from the 1980's. Some of my other works from this time are for 5 electric guitars, 18 trombones, 8 cellos, and 4 accordions. I consider each of these ensembles to be one "big instrument". In all of these pieces I used principles of what I call "exponential structure", in which elements such as time, harmonic motion, rhythmic and timbral development, sound density, etc. are controlled by exponential factors. These are not abstract constructs, but formal ideas based on the emotional thrust of the sounds and of the piece as a whole.
