Paul Hindemith, born on November 16, 1895, in Hanau and died on December 28, 1963, in Frankfurt am Main, was a significant German composer of the modern era. At the age of only 19, he assumed the position of concertmaster of the Frankfurt Opera Orchestra, which initially suggested a career as a violinist. However, his true passion unfolded in playing the viola. In the 1920s, he achieved considerable acclaim as a violist, both as a member of the Amar String Quartet and as a soloist in important performances.
Since the viola was historically rarely used as a solo instrument, and even Bach left no works for the modern viola, Hindemith saw it as his mission to expand the repertoire for this instrument. His compositions show clear influences from Reger, who further developed Bach's style for string instruments. The first viola sonata, Op. 11 No. 5, is considered a personal declaration of his artistic goals and marks the beginning of a new creative period.
Since the viola was historically rarely used as a solo instrument, and even Bach left no works for the modern viola, Hindemith saw it as his task to expand the repertoire for this instrument. Hindemith composed numerous important solo pieces for the viola, including seven sonatas for solo viola or with piano accompaniment. His later works, such as the Sonata Op. 25 No. 1 and the Sonata Op. 31 No. 4, illustrate his stylistic shift towards modern music. Particularly in the third sonata, Op. 31 No. 4, he combines virtuosic elements with lyrical freedom. His last sonata for solo viola was composed during a difficult period and possesses an almost romantic, celebratory character, before the composer was forced into exile.
