Henri Vieuxtemps's Viola Sonata in B-flat major, Op.
36 is a composition for viola (or cello) and piano composed in 1860, and published in 1862.
[1][2] Vieuxtemps began composing the Viola Sonata in 1860 at around the same time as he began work on his fifth violin concerto; it was some twelve years after his last composition for this combination of instruments, the Élégie, Op.
The Viola Sonata was completed in late 1860 with the first performance, featuring the composer and pianist Arabella Goddard, taking place on 21 January 1861, at St James's Hall in London.
[2] It was published by J. Schuberth & Co. in late 1862, with a dedication to King George V of Hanover.
