Swiss composer, Frank Martin wrote 2 Sonatas for Violin and Piano: Op. 1, entitled by the composer, Sonata for Piano and Violin and a later second Sonata #2 for Violin and Piano. The first sonata has a distinct "romantic" grandness to it while in the second sonata Martin experimented with atonality. In addition to writing a Ballade for Cello and Piano, Frank Martin also wrote Ballades for Flute and Piano and Trombone and Piano. Soon to be released by ComMedia LLC. The Chaconne for Piano and Cello is influenced by JS Bach and sounds very much like a 2-Part Invention for cello and piano.
