It is hardly a coincidence that Chopin dedicated each of his Three Waltzes op. 64, written in 1847, to a baroness or countess: aristocratic ladies offered the ideal public for this music, both as performers and as hostesses of musical events. This C sharp minor Waltz in a Slow Tempo. dedicated to his student the Baroness Charlotte de Rothschild, soon surpassed such social barriers. With its soulful sighing motif, it ranks today as one of Chopin's most popular melodies.
