Petite symphonie concertante

Petite symphonie concertante, Op. 54 is a composition by Swiss composer Frank Martin, commissioned in 1944 by its dedicatee, conductor Paul Sacher, and finished in 1945. Martin chose an unusual scoring at Sacher's request: string orchestra divided into two groups with harp, harpsichord, piano as soloists rather than continuo, justifying the title (and evoking the fifth of Bach's Brandenburg Concertos). Written for the revival harpsichord, it is an uncommon 20th-century sinfonia concertante.
