The Robertsbridge Codex (1360) is a music manuscript of the 14th century. It contains the earliest surviving music written specifically for keyboard.
The term codex is somewhat misleading: the musical section of the source comprises only two leaves, bound together with a larger manuscript from Robertsbridge, Sussex, England.
It contains six pieces, three of them in the form of the estampie, an Italian dance form of the Trecento, as well as three arrangements of motets.
