(1470–1547) published an edition of the poet Petrarch (1304–1374); and published the Oratio pro litteris graecis (1453) about achieving graceful writing by applying Latin prosody, careful attention to the sounding of words, and syntax, the positioning of a word within a line of text. As a form of poetry, the madrigal consisted of an irregular number of lines (usually 7–11 syllables) without repetition. Second, Italy was the usual destination for the oltremontani ("those from beyond the Alps") composers of the Franco-Flemish school, who were attracted by Italian culture and by employment in the court of an aristocrat or with the Roman Catholic Church. The composers of the Franco-Flemish school had mastered the style of polyphonic composition for religious music, and knew the secular compositions of their homelands, such as the chanson, which much differed from the secular, lighter styles of composition in late-15th- and early-16th-century Italy. 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. The madrigal slowly replaced the frottola in the transitional decade of the 1520s. The early madrigals were published in Musica di messer Bernardo Pisano sopra le canzone del Petrarcha (1520), by Bernardo Pisano (1490–1548), while no one composition is named madrigal, some of the settings are Petrarchan in versification and word-painting, which became compositional characteristics of the later madrigal. The Madrigali de diversi musici: libro primo de la Serena (1530), by Philippe Verdelot (1480–1540), included music by Sebastiano Festa (1490–1524) and Costanzo Festa (1485–1545), Maistre Jhan (1485–1538) and Verdelot, himself. In the 1533–34 period, at Venice, Verdelot published two popular books of four-voice madrigals that were reprinted in 1540. In 1536, that publishing success prompted the founder of the Franco-Flemish school, Adrian Willaert (1490–1562), to rearrange some four-voice madrigals for single-voice and lute. In 1541, Verdelot also published five-voice madrigals and six-voice madrigals. The success of the first book of madrigals, Il primo
