Third, the printing press facilitated the availability of sheet music in Italy. The musical forms then in common use — the frottola and the ballata, the canzonetta and the mascherata — were light compositions with verses of low literary quality. Those musical forms used repetition and soprano-dominated homophony, chordal textures and styles, which were simpler than the composition styles of the Franco-Flemish school. Moreover, the Italian popular taste in literature was changing from frivolous verse to the type of serious verse used by Bembo and his school, who required more compositional flexibility than that of the frottola, and related musical forms.
