Written in 1997, Shifting Waves
is a combination of continually changing ostinatos. The center marimba serves as
the rhythmic and melodic focus of the piece as it combines 2 and 3 note patterns
in 6/8 and later 2 and 5 note patterns in 5/4, all over constant eighth notes.
After a brief lyrical interlude in the middle of the ensemble, the texture of
the piece begins to gradually thicken. Lighter sounds (i.e. high hat, wood
block) are systematically replaced with heavier sounds (snare drum, bass drum,
etc.), leading to a strong reprise of the opening figure and a unison
conclusion.
