Kreutzer sonata and the concerto are both very advanced pieces, they are not as technically challenging as the Paganini Caprices but they require very mature technique and are among the most musically challenging pieces to play. It is commonly known as the Kreutzer Sonata after the violinist Rodolphe Kreutzer, to whom it was ultimately dedicated, but who thoroughly disliked the piece and refused to play it. For its daring thoughts about marriage and undermining family values, The Kreutzer Sonata was banned by censors immediately after publication. Furthermore, in the U.S., the print run of newspapers which published a translation of the novella was also banned.
