Internationally renowned composer and percussionist Ney Rosauro designed this special series of marimba and vibraphone mallets to reflect the sound he desires for his award-winning compositions. Rattan shafts and rubber cores coupled with special yarn and cord choices assure the player of a pure and natural sound that projects the full capabilities of the instrument. The M221 Soft mallet is for rich bass and well defined fundamental in the lower register. The M222 Medium Soft is for rich bass and well defined fundamental in the lower register. The M223 Medium Hard is a versatile and general mallet that produces full and natural sound throughout the entire keyboard. The M224 Hard mallet cuts well, but still maintains a pure fundamental sound.
