Watch the Melting Glaciers is an intermediate level composition for marimba (with two mallets) and piano. It utilizes througout, the rhythm derived from the polyrhythm four over three, which is also found in the text of the title itself. Delineate in seven sections, Glaciers is, as the title may suggest, a programmatic composition, loosely constructed around the subject of global warming. Built on a major/minor tonality throughout, it has a sound that is both accessible and contemporary. The element of improvisation is employed in one section and improvisational suggestions are offered in the performance notes. This piece comes with a full, bound score and includes a CD-Rom containing a video of the piece being performed, an audio recording for reference, and both the solo and accompaniment parts available for printing.
