Mason Lynass composed his percussion ensemble piece Tesserae so that it could be performed by 3 or 4 players and still hold its laid-back, groovy feel. It has elements of minimalism and "drum and bass" grooves. Depending on whether it's performed as a trio or a quartet, the piece can be felt in two different ways: if performed by 3 players, the piece can be felt in 12/8 time and if performed by 4 players, the piece can be felt in 3/4 time.This piece was the winning work in Portland Percussion Group's 2017 Call for Scores and was premiered in 2017 at the Shout House in Portland, Oregon.Tesserae comes as a full, bound score and includes a CD-ROM containing individual parts for printing as well as a full audio recording.Number of players: 3-4Difficulty: Intermediate/advancedInstrumentationPlayer 1: Vibraphone, sizzle cymbal (shared w/Player 2)Player 2: Marimba (5 octave), sizzle cymbal (shared w/Player 1)Player 3: Shaker, two toms, bongos, pedal bass drum, glockenspiel, suspended cymbalPlayer 4 (Optional): Drum set
