Partimenti and the Power of Improvisation

Like a lead sheet in popular music, a partimento gives a performer a single line of music to aid in the performance of a multivoice composition. Lead sheets provide a simplified melody and symbols for chords. Partimenti provide a bass and sometimes figured-bass numbers to indicate specific intervals. In both cases the reconstruction works well if the performer has a good knowledge of the style of music involved and a memory for the kinds of musical patterns needed. In Naples, children played the written partimento with their left hands at a small harpsichord. With their right hands they improvised the types of melodies, chords, and counterpoints implied by the bass. Beginners may have improvised mostly simple chords. Intermediate-level students improvised melodies and counterpoints. And advanced students developed highly contrapuntal realizations that included partimento fugues.
