Written by Sarah Wallin Huff in 2010, one of our favorite pieces in String Theory is called “Sonata Moderna" (previously known as "Sonata Sopra"). It was originally written by Biagio Marini (c. 1597 – 1665) under the title of "Sonata sopra la Monica." Marini was a Baroque violinist and composer who lived and worked in northern Italy. Born in Brescia in c. 1597, Marini served as violinist under Monteverdi at St Mark’s in Venice from 1615 – 18. He also worked as a court musician in Parma from 1621 – 3 and as a Choirmaster for S. Maria della Scala in Milan in 1649[1].
