ABSTRACT:
The keyboard or pianos and similar musical instruments has key shanks (levers) which rest on a balance rail from which balance pins project. The balance rail is mounted on a strengthening rail which is keyed into one of two parallel slots in an underlying support wall. There are two balance-pin holes in each shank. The distance between the two holes corresponds to the distance between the two parallel slots in the underlying support. The result is that assembly or adjustment for either light or heavy touch may be achieved at almost no added manufacturing cost. The touch depends upon which slot is employed and which hole is employed.
