Marchetto da Padova [ Marchetus de Padua ]
- Jan Herlinger
[ Marchetus de Padua ]
( fl 1305–19). Italian music theorist and composer . In his Lucidarium in arte musice plane he developed the theory of ‘permutation’ to account for the chromatic progressions common in music of his time, proposed a division of the whole tone into five equal parts that proved a milestone in the history of tuning, and developed a comprehensive theory of mode that accommodated melodies irregular in range or construction. His Pomerium in arte musice mensurate, the earliest major treatise dealing systematically with a mensural system that permitted a duple as well as a triple division of the breve, became the foundation of the mensural theory of the Italian Trecento.
There is documentary evidence that a ‘Marchetus’ was appointed teacher of the boys at Padua Cathedral early in 1305, held that office still in July 1306, and donated the income from a benefice to the cathedral in the summer of 1307...
