The Waltz in A flat, Op.42, was written in 1840. Wilhelm von Lenz recalled Chopin playing it: ‘The waltz, springing from the eight-bar trill, should evoke a musical clock, according to Chopin himself. In his own performances … he would play it as a continuous stretto prestissimo with the bass maintaining a steady beat – a garland of flowers winding amidst the dancing couples!’
