Piano Concerto, Op. 42

Arnold Schoenberg's Piano Concerto, Op. 42 (1942) consists of four interconnected movements: Andante (bars 1–175), Molto allegro (bars 176–263), Adagio (bars 264–329), and Giocoso (bars 330–492) (Alegant 2002–2003, 74). A concerto for piano, the piece features consistent use of the twelve-tone technique and only one tone row ("the language is very systematic, it's the true dodecaphonic Schoenberg" (Aimard 2010, 0:40)), though not as strictly as Schoenberg once required.[vague] Around 20 minutes long, its first performance was given February 6, 1944 (Meyer 2012, 312) at NBC Orchestra's Radio City Habitat in New York City, by Leopold Stokowski and the NBC Symphony Orchestra, with Eduard Steuermann at the piano (Anon. 2009).
