| Abstract: |
An improved method for the inertial balancing of a plurality of key assemblies having keysticks within a musical instrument keyboard wherein an individual front weight is predetermined for each stick, the method consisting of calibrating each of the keysticks to an identical selected front weight prior to installing the key leads to a preset pattern which result in the final individual front weight for each key assembly.

What is claimed is:
1. In the method of balancing key assemblies for musical instrument keyboards having a plurality of said assemblies each of said assemblies having a keystick, each of said assemblies relating to a note of the instrument wherein a specified keystick front weight is determined for each of said key sticks, the improvement which comprises the steps of:
- specifying a uniform calibration keystick front weight for a selected portion of said keyboard;
- selecting and determining the position of at least one appropriate module key lead in each of said keysticks, said module key lead arranged to produce said specified front weight for each of said key sticks when added to said uniform calibration front weight;
- drilling a mounting hole for each of said module key leads in each of said key sticks;
- placing the key stick on a front weight measuring jig;
- adding and positioning a calibration key lead to each of said key sticks to produce said uniform calibration front stick weight;
- drilling a mounting hole for each of said calibration key leads;
- installing the appropriate calibration key leads and module key leads for each of said key sticks to achieve said specified front weight for each of said key sticks.
