Girolamo Alessandro Frescobaldi was an Italian composer and virtuoso keyboard player. Born in the Duchy of Ferrara, he was one of the most important composers of keyboard music in the late Renaissance and early Baroque periods. A child prodigy, Frescobaldi studied under Luzzasco Luzzaschi in Ferrara, but was influenced by many composers, including Ascanio Mayone, Giovanni Maria Trabaci, and Claudio Merulo. Girolamo Frescobaldi was appointed organist of St. Peter's Basilica, a focal point of power for the Cappella Giulia, from 21 July 1608 until 1628 and again from 1634 until his death.

The Duchy of Ferrara was a state in what is now northern Italy. It consisted of about 1,100 km2 south of the lower Po River, stretching to the valley of the lower Reno River, including the city of Ferrara. The territory that was part of the Duchy was ruled by the House of Este from 1146 to 1597.
