Schoenberg wrote his expressive Violin Concerto between 1934 and 1936. Structurally it’s Neoclassical, consisting of a sonata form allegro, an andante, and a rondo finale. Harmonically it’s 12-tone, but perhaps the violinist’s greatest challenges are technical ones. Jascha Heifetz apparently claimed it required six fingers, before Berg Violin Concerto commissioner Louis Krasner mastered it for the 1940 premiere. The four seamlessly running movements of the Piano Concerto from 1942 are also 12-tone, although with tonal-sounding intervals in its row, and a surprise C major final chord. By contrast, Verklärte Nacht is clearly tonal, albeit highly chromatic. Inspired by Richard Dehmel’s poem of the same name, this 1899 work portrays a couple walking in the night, whose troubles—the woman is pregnant with another man’s child— are eventually transfigured by their love, and the night’s beauty.
