The first instrument of the string family with finger-keys was the clavicytherium, or clavitherum, which the Italians produced about the thirteenth century. This was a form of harp with gut strings in which a key-board was employed with finger-keys to move the mechanical leather plectra used for plucking the strings in lieu of the fingers.
The clavichord, an instrument used up to a recent date, came into existence about the same period as the foregoing, and was another

For the first time gut strings were set aside for wire, which were thrown into musical vibration by a tangent moved by a key, thus forming a rude anticipation of the first piano-action mechanism. Sebastian Bach used the instrument in his home for purposes of inspiration and practice, while Mozart is said to have carried one on his musical journeys. Beethoven was also partial to the instrument. It had very many advantages over the harpsichord, the only popular instrument of the Mozart and Bach era. For instance, it was possible to produce rude piano e forte effects—which results, first attained in the piano, gave it its title—while it had the faculty of action repetition, and a pleasing attribute of being able to simulate human feeling, such as a violinist or vocalist can produce by sliding from interval to interval. As compared with the piano, however, or even the improved harpsichord of the last century, it was a mere toy.
The first mention of the instrument discovered in England goes back to 1500, when William Cornish, in his work, A Treatise between Trouth and Informacion. says:
"The clavichorde hath a tunely knyde
As the wyre is wrested high and low."
It may have been known previously, however, in that country. Meanwhile, the Germans were generally esteemed as leading clavichord makers at that period.
The virginal and spinet, both forms of the clavicytherium, came next. In these instruments brass-wire strings superseded gut. Instead of a leather plectrum for plucking the strings, a
