Tank Time by Brian Slawson is a fun and entertaining introduction to counting and playing triplets for a beginning ensemble. It also requires a full range of dynamics while keeping a steady beat. It requires 9-10 players (the hand cymbals and bass drum parts may be covered by a single player if a bass drum/cymbal attachment is available). Two of the three marimba parts are shared on a single 4.3-octave (low A) instrument. The timpani part only requires two drums. Tank Time ships as a fully bound score and includes individual parts in PDF format for either printing or tablet viewing.
