 The 1623 collection is of particular importance because of Piccinini's lengthy preface, which includes a detailed manual on performance, as well as claims to have invented the archlute (Piccinini also made important modifications to the chitarrone).Piccinini concentrated on toccatas, courantes and galliards, as well as different kinds of variations.No other works by Piccinini are known; his music for "La selva sin amor", the first opera performed in Spain, composed by his brother Filippo Piccinini is lost.
