In 1944, Schoenberg wrote a short canon in honor of the birth of Richard Rodzinski, son of the famous conductor Arthur Rodzinski. The text is priceless:
I am almost sure, when your nurse will change your diapers,
she will not sing you one of my George Songs,
nor of my Second String Quartet;
but perhaps she stills you:
Sleep, Richard, Sleep! Your father loves you!
