François Dieupart, also known as Charles Dieupart, was a French composer who made his career in England. He was involved in a venture to promote Italian opera in London. This project was derailed by the success of Handel’s operas from 1710 onwards. Nevertheless, Dieupart seems to have enjoyed a solid reputation as a performer, orchestral musician and harpsichord teacher. His works enjoyed a certain success, notably his 6 suites for harpsichord, widely distributed in Europe and said to have inspired Johann Sebastian Bach’s English suites.

The Concerto a due cori contrasts two groups of violins supported by instrumental basses. Those in the Coro primo are reinforced by flutes (independent or doubling) and those in the Coro secondo by a viola part. In five movements (1. Andante - 2. Largo - 3.Vivace - 4. Grave e staccato - 5. Allegro), this work in E minor is relatively easy to play and is equally enjoyable for all. Nearly a quarter of an hour in length, it is ideal for showcasing the orchestra in a vocal programme.

This concerto joins the two concerti grossi, one in B minor, the other in B flat major, as well as the two concertos in 5 parts, one for violin, the other for flute or oboe, already published.
