Program Note
Glimmerglass is my ninth concerto collaboration, this one being for
solo flute, chamber winds, and percussion. The concept for this flute
concerto had been in my mind for several months, as I was grasping how
to feature this virtuosic and beautiful instrument. In comparison to my
previous concertos, I wanted this one to have a brighter and shimmery
texture of sound, one that could match the timbre of the flute.
This led to the naming of this piece Glimmerglass Concerto, where
the definition of Glimmerglass is a “vibrant reflection of sunlight on a
watery surface”. Through this naming, the two movements (Mirrors and
Echoes) play with different reflections of sound and lyricism. This is
most reflected in the percussion writing, where I wanted to have this
shimmery cacophony of sound while the flute can soar above.
This piece was commissioned by the University of Colorado Boulder
College of Music for the CU Wind Symphony and their Professor of
Flute, Christina Jennings.
