viola in more creative ways when he wrote his six string quintets. The viola quintets use two violas, which frees them (especially the first viola) for solo passages and increases the variety of writing that is possible for the ensemble. Mozart also wrote for the viola in his Sinfonia Concertante, a set of two duets for violin and viola, and the Kegelstatt Trio for viola, clarinet, and piano. The young Felix Mendelssohn wrote a little-known Viola Sonata in C minor (without opus number, but dating from 1824). Robert Schumann wrote his Märchenbilder for viola and piano. He also wrote a set of four pieces for clarinet, viola, and piano, Märchenerzählungen. Max Bruch wrote a romance for viola and orchestra, his Op. 85, which explores the emotive capabilities of the viola's timbre. In addition, his Eight pieces for clarinet, viola, and piano, Op. 83, features the viola in a very prominent, solo aspect throughout. His Concerto for Clarinet, Viola, and Orchestra, Op. 88 has been quite prominent in the repertoire and has been recorded by prominent violists throughout the 20th century.] From his earliest works, Brahms wrote music that prominently featured the viola. Among his first published pieces of chamber music, the sextets for strings Op. 18 and Op. 36 contain what amounts to solo parts for both violas. Late in life, he wrote two greatly admired sonatas for clarinet and piano, his Op. 120 (1894): he later transcribed these works for the viola (the solo part in his Horn Trio is also available in a transcription for viola). Brahms also wrote "Two Songs for Alto with Viola and Piano", Op. 91, "Gestillte Sehnsucht" ("Satisfied Longing") and "Geistliches Wiegenlied" ("Spiritual Lullaby") as presents for the famous violinist Joseph Joachim and his wife, Amalie. Dvořák played the viola and apparently said that it was his favorite instrument: his chamber music is rich in important parts for the viola. Another Czech composer, Bedřich Smetana, included a significant viola, originally viola d'amore part in his quartet "From My Life": the quartet begins with an impassioned statement by the viola. Bach, Mozart, and Beethoven all occasionally played the viola part in chamber music. The viola occasionally has a major role in orchestral music, a prominent example being Richard Strauss' tone poem Don Quixote for solo cello and viola and orchestra. Other examples are the "Ysobel" variation of Edward Elgar's Enigma Variations and the solo in
