Flash Mob

“Flash Mob” is a fun and accessible quartet written for minimal instruments and appropriate for intermediate-level players. Groovy and dancelike, it would be perfect for a run-out concert or opener on a more formal program. The composer cites the inspiration of a flash mob as being “something exciting and accessible that will grab and hold the audience’s attention.” Another interpretation might be the minimal resources required, evoking a sort of “pop-up concert” in the middle of a crowd.

The piece begins with solo marimba and is subsequently joined by layering of vibraphone and the two percussion parts. One percussion player utilizes splash cymbal and hi-hat, while the other performs on a muffled tom-tom — creating a makeshift drum set. The keyboard percussion parts move in constant counterpoint with each other throughout the piece, frequently swapping melody for rhythmic accompaniment, while the percussion parts execute more repetitive groove rhythms. Sections recur in a manner reminiscent of a pop tune, including a set of two-measure “breaks” for each instrument in the middle of the piece. At three minutes in length, it will satisfy a wide variety of listeners — from musicians who can appreciate the clever interlocking rhythms to those who enjoy catchy melodies and a constant beat.

The marimba and vibraphone parts utilize two mallets throughout with a fair amount of repetition. The percussion parts are also repetitive and mostly use eighth- and sixteenth-note rhythms. However, all players must execute their part with minimal, if any, doubling from the others, making this a true chamber-music experience for younger players. This confidence is also necessary to navigate the constantly shifting roles of melody and accompaniment, as well as the solid, dancelike style of the music.
