ABSTRACT:
Each key of the pedalboard is supported and guided for pivotal movement in a vertical plane by a steel strip secured to the underside of each key adjacent the midportion thereof. The rear end of each key is operatively connected to a transversely extending rear frame for horizontal reciprocating movement perpendicular to the rear frame and the forward end of each key is disposed between transversely extending upper and lower and front frame members for limited vertical movement therebetween. The forward end of each steel strip is secured to the lower front frame member to normally bias the forward end of each key into engagement with the upper front frame member.
