Hoste da Reggio (also L'Hoste, L'Osto, Oste, and Bartolomeo Torresano[1]) (c. 1520–1569) was an Italian composer of the Renaissance, active in Milan and elsewhere in northern Italy.
The governor of Milan, Ferrante Gonzaga, hired him in the 1540s; the exact post is not known but may have involved overseeing the music at the church of Santa Maria della Scala.
In 1563 he resumed his previous duties at S. Calimero, staying there until 1567, when he left Milan for Bergamo, where he served as maestro di cappella at Santa Maria Maggiore.
Some of the methods of madrigal composition common around 1550 which can be found in Hoste's music include chromaticism, unusual chord progressions, especially around cadences, and note nere (black-note) writing.
This most likely shows the influence of Francesco Corteccia, the famous musician and madrigalist to the Medici in Florence, who was consciously melding art and popular music styles.
