This Sonor deep bass chime bar is crafted from palisono, a synthetic that resists the effects of moisture. Play these chimes on the floor, in the hand, or on a table. The resonance plate on these Sonor bars adjusts to provide optimum vibration.

Resonator bars have a variety of uses in Orff music programs, including general music and movement activities, and music therapy. The deep bass bars may be used individually or in combination with a deep bass xylophone. When used with contra and sub-contra bass bars they can reproduce timpani voicing.
