The early Piano Sonata, Op. 4 offers interesting insights into the young Chopin's compositional development. in all probability written during his student years at the Warsaw Conservatory and highly prized by Chopin himself, the nineteen-year-old composer presented the work to the publisher Tobias Haslinger on a visit to Vienna. But the publisher put off the still unknown composer. It was only when Chopin was at the height of his fame that Haslinger saw a possibility to do business – but this time it was Chopin who declined. Thus his first sonata was never published during his lifetime.
