Sonata No. 4 for solo viola (1937) by Paul Hindemith
Published by Schott
Both as violist and composer, Paul Hindemith (1895-1963) was thoroughly involved with contemporary music--he was a leading exponent of New Objectivity and neoclassical styles, and was much in demand as a soloist, premiering, among other works, Walton's Viola Concerto. During the rise of fascism in Germany, he emigrated to the United States, where he became a much-respected pedagogue.
Hindemith expanded the repertory for viola with many substantial and demanding works, including several unaccompanied solo sonatas. His last of these, Sonata No. 4 for Solo Viola, was written during his first concert tour of the United States in 1937 and is the only solo string sonata from Hindemith's austere middle period.
