Containing pieces for 2, 3, and 4 mallets, Motor On is another collection of keyboard solos by percussion educator Matthew Weyer that helps fill the gap between beginning and advanced works specifically for solo vibraphone. These pieces provide the performer with intriguing music that involves different aspects of vibraphone playing: pedaling, mallet dampening, varying motor speeds, dead-strokes, and mallet-shaft playing. 2 Mallets: Appalachian Highway (Med-Easy • 1’00”) 2 Mallets: Classic City (Med-Easy • 1’20”) 3 Mallets: Low Country (Medium • 1’40”) 4 Mallets: Rush Hour (Medium • 1’50”) 4 Mallets: Blue Sky (Med-Advanced • 2’10”) 4 Mallets: Piedmont (Med-Advanced • 1’50”) Motor On ships as a fully-bound book with a snazzy cover design by fellow Tapspace artist, Jesse Mattson.
