Jacopo da Bologna was an Italian composer of the Trecento, the period sometimes known as the Italian ars nova. He was one of the first composers of this group, making him a contemporary of Gherardello da Firenzeand Giovanni da Firenze. He concentrated mainly on madrigals, including both canonic (caccia-madrigal) and non-canonic types, but also composed a single example each of a caccia, lauda-ballata, and motet (Marrocco 1954, 14–16, 27–28; Fischer and d'Agostino 2001).
His setting of Non al suo amante, written about 1350, is the only known contemporaneous setting of Petrarch's poetry (Petrobelli 1975; Fischer and d'Agostino 2001).
Jacopo's ideal was "suave dolce melodia" (sweet, clean melodies) (Fischer and d'Agostino 2001). His style is marked by fully texted voice parts that never cross. The untexted passages which connect the textual lines in many of his madrigals are also noteworthy (Cuthbert 2006, 192).
