Arcangelo Borsaro (fl. 1587 - 1616), an Italian composer, born in Reggio Emilia, Italy. He wrote a anthology titled Sacri sacrificii ser gli deffonti.

Concerti based on the formal outline of the rondo constituted an important segment of the religious repertoire, especially compositions for large ensembles, by the Venetians and other composers under their influence (including those active in the trans-Alpine countries), written at the end of the 16th century and in the first decades of the 17th century.
These works consisted of a refrain, that appeared several times within the work (repeating both the text and its musical setting) alternating with couplets; sometimes the concerti also included instrumental introductions. The refrain was a homogeneous, independent section performed by the whole ensemble. It was usually in triple meter, and in homorhythmic texture with little rhythmic variety. The refrain were characterized by static melodies with a narrow range, syllabic text treatment, a declamatory character, and the simplest harmonies. The couplets contrasted with the refrains by being in duple meter and by using a variety of performing forces (e.g. intertwined segments composed for solo voices, ensembles - primarily duets - and short portions for tutti). Here, the composers juxtaposed homorhythmic and imitational textures, varied the melodic lines (of a wide range), and varied the rhythms and tempi.
These types of works were written by the best Venetian composers (e.g. Giovanni Croce, Giovanni Gabrieli, Claudio Monteverdi, Alessandro Grandi), as well as by lesser known composers working in Venice or in other centers near Venice (e.g. Carlo Milanuzzi, Giovanni Battista Stefanini, Francesco Croati, Arcangelo Borsaro, Francesco Cavallo, Giovanni Maria Sabino and others).
