ABSTRACT:
A musical movement which comprises, primarily, a metal comb produced by a chemical machining process and, secondarily, a drum in the shape of a frustum of a stepped comb. The comb is advantageously provided with means whereby it can be fastened to a movement base without employing bolts or the like and the drum steps advantageously have projections, for co-operation with the comb teeth, that do not extend further radially than do the immediately neighboring drum steps of larger size.
