This series of mallets is designed to meet the meticulous demands of former NEXUS percussionist, composer, and Percussive Arts Society Hall of Fame Member, Robin Engelman. The multi-percussion/bass marimba mallet was designed to produce a rich fundamental and for use as a multi-percussion implement. The 6 additional models of ensemble mallets are structured with choir voices in mind. The mallets are voiced as follows: IP702 / IP705 tenor voice, IP703 / IP706 alto voice, IP704 / IP707 soprano voice. The yarn models are designed to produce a warm legato articulation, while the cord models create a stronger staccato articulation. Specially designed with the mallet ensemble in mind, this series covers the broad spectrum of tonal qualities to fulfill all of the needs of today's modern percussion ensemble.
