KatThanks! ...
1700-1800 - TRUE - John Shaw invented the Tuning Fork in 1711. He became a royal trumpeter in 1688 and rose to Sergeant Trumpeter in 1708. He was also lutenist to the Chapel Royal (appointed in 1706). The tuning fork was to help him tune his lute. He died in 1752. The first pianoforte had been described in 1709 by Scipione Maffei.
1300-1400 and 1400-1500 ... any more?
