A Piano Sonata
Brahms's Sonata for Violin and Piano no 3 in D minor, Op. 108, was written between 1886 and 1888, during the Romantic Era. It was the last in a triptych of violin sonatas, and was first performed in Budapest in 1888. Dedicated to a friend and colleague of Brahms, Hans von Bulow, this sonata has four movements, which was a departure from Brahms's preceding sonatas, each of which had three movements. The movements were: 1. Allegro 2. Adagio 3. Un poco presto e con sentimento 4. Presto Agitato
