Beethoven’s Sonata No 14 of 1802 was revolutionary for rejecting traditional fast-slow-fast architecture in favour of the hypnotic slow first movement that earned it its ‘Moonlight’ nickname. A graceful Allegretto follows, before a finale of angry, percussive rhythms. Liszt’s nocturne-like Consolation No 3 in D flat major of 1850 may have been a tribute to Chopin, who died the previous year. His virtuosic Mephisto Waltz No 2, penned 30 years later, was then dedicated to Saint-Saëns, and starts and ends with the diabolical, unresolved tritone interval. Chopin’s Barcarolle in F sharp minor evokes the lulling songs of Venetian gondoliers, although its dramatic climax moves beyond traditional barcarolle territory. His third and final Piano Sonata of 1844 equally saw him bring his distinctive voice to a traditional form. After a first movement mostly based on its strong opening theme comes a brief Scherzo and a nocturne-like Largo, before an urgent, bravura-filled, rondo form finale.
