Bacco, Bacco is a lively carnival song by Francesco Corteccia, court composer to Cosimo I de' Medici in Florence. It was part of the intermedii (musical interludes) composed for the lavish wedding celebrations of Cosimo I and Eleonora di Toledo in 1539. These were among the first secular intermedii in history, featuring mythological themes with Bacchus (Bacco) representing joy and celebration. Corteccia's music typifies the early Florentine madrigal style with its simple polyphony and festive character.
