Paul Hindemith's Der Schwanendreher (literally, "The Swan turner") is a concerto for viola and orchestra.
 "Der Schwanendreher" occupies a place at the core of the viola concerto repertoire, along with the concertos by Walton and Bartók.
 It was composed in 1935 and premiered by the composer himself at a performance in Amsterdam on 14 November 1935.
 Each movement is based on a separate medieval German folk song, thus, it is sometimes referred to as the "Concerto from Old Folk Songs".
 This composition draws its title from the final movement's folk song base, "Aren't you the swan turner?"

The Concerto for Piano and Orchestra in G minor, Op. 33, is the only piano concerto by Czech composer Antonín Dvořák.
 Written in 1876, it was the first of three concertos that Dvořák completed, followed by the Violin Concerto, Op. 53 from 1879 and the Cello Concerto, Op. 104, written in 1894–1895.

The Viola Concerto by William Walton was written in 1929 for the violist Lionel Tertis at the suggestion of Sir Thomas Beecham.
 The concerto carries the dedication "To Christabel" (Christabel McLaren, Lady Aberconway).
 But Tertis rejected the manuscript, and composer and violist Paul Hindemith gave the first performance.
 The work was greeted with enthusiasm.
 It brought Walton to the forefront of British classical music.
 In "The Manchester Guardian", Eric Blom wrote, "This young composer is a born genius" and said that it was tempting to call the concerto the best thing in recent music of any nationality.
 Tertis soon changed his mind and took the work up.
