 Starting in the last decades of the century, Italian composers such as Marchetto Cara and Bartolomeo Tromboncino wrote light, courtly songs called "frottole" for the Mantuan court of Isabella d'Este.With the support of the Medici, the Florentine Mardi Gras season led to the creation of witty, earthy carnival songs called "canti carnascialeschi".The 16th century saw the advent of printed polyphonic music and advances in instrumental music, which contributed to the international distribution of music characteristic of the Renaissance.
