A Partimento is a sketch, written out on a single staff, whose main purpose is to be a guide for the improvisation ("realization") of a composition at the keyboard. Partimento differs from simple basso continuo accompaniment in that the result is a complete, fully-realized composition. Partimenti were central to the training of European court musicians from the late 1600s until the early 1800s. They had their greatest influence first in Italian conservatories, especially at the music conservatories of Naples, and then later at the Paris Conservatory, which emulated the Neapolitan conservatories.
