[9] In order to aid Oscar Levant, for whom the Piano Concerto was originally composed, Schoenberg provided what he called "a few explanatory essays":[10] Life was so easy Suddenly hatred broke out A grave situation was created But life goes on[11] Although this program was not included in the published score, Schoenberg told his student Marion Bauer that "for sometime [sic] I have not been against program music".
[13] The concerto has been compared with the music of Johannes Brahms by Mitsuko Uchida,[14] Sabine Feisst[15] and AllMusic.
