English: Original design by Keith Hill - Instrument Maker of his improvements in Pedal Harpsichord Making Opus 70#1 and Opus 74 created in 1980. Design compressed the width of the pedal instrument from 4 feet wide to 2 feet thus concentrating and focusing the sound for superior acoustic balance between the pedal instrument and the manual harpsichord. This perched the pedal harpsichord above the pedal board, using stickers (organ technology) to connect the pedals to the keys inside the pedal harpsichord. These two changes then allowed the player to easily tune the pedal instrument (what was impossible before when the pedal instrument sat directly on the floor in front of the pedal board...(how all prior pedal harpsichords were made). This resulted in a more focused sound in the pedal instrument that blends better with the more focused manual harpsichord above it. The inventor chose to not patent the design, rather granted other harpsichord makers who asked to use the design the privilege of using the design to build their own pedal harpsichords
