Ignazio Donati (c. 1570 - 21/01/1638) was an Italian composer of the early Baroque era. He was one of the pioneers of the style of the concertato motet. Donati was born in Casalmaggiore, near Parma. Little is known about his earliest years, but he must have had a thorough early musical training, and his succession of posts at various cathedrals in Italian towns is well documented: he served successively at Urbino, Pesaro, Fano, Ferrara, Casalmaggiore, Novara, and Lodi, eventually acquiring the prestigious post at Milan Cathedral in 1629, which he kept with one short break until his death.
