Sonor individual bass bar, pitch C; overtone-tuned fiberglass bar with wood resonating chamber. This bar is the same pitch as the lowest note on a bass xylophone. If you have other Sonor contra and sub-contra bass bars, this would be the top note to complete the octave that starts with the sub-contra bass C. Slight adjustments in tuning may be made by means of the adjustable black tuning plate that is under the bar. Price per individual bar. Mallets must be purchased separately. Dimensions approx. 21-3/4 in. long x 8-3/4 in. high x 3-1/4 in. wide.
