His harpsichord dances are of three types: dances in triple meter, dances in triple meter paired with "saltarellos," and pieces which use a ground bass. Most of the works with ground bass use some type of "romanesca" pattern, consisting of a line descending by fourth, rising by step, then descending again by fourth or fifth, rising by step, and so forth (the Pachelbel Canon, probably written several decades after Picchi's death, is probably the most famous example of variations over a "romanesca" bass).
