Mozart penned his single-movement Adagio K. 540 in 1788, between his ‘Coronation’ Piano Concerto and the premiere of Don Giovanni. A masterpiece of subdued, melancholic beauty, its dramatic masterstroke comes at its conclusion when, after a tragedy-flecked series of chromatic descents, it finally settles in major-tonality peace. Beethoven’s ‘Pastoral’ Sonata No. 15 strikes for its overall lack of storminess, meaning its isolated outbursts are especially impactful. Characteristics that sparked its nickname include its outer movements’ triple time and pedal notes. Schubert’s Piano Sonata No. 17 was the happy product of an 1825 alpine summer holiday. An upbeat Allegro vivace leads to a serene second movement and a dancing Scherzo. Then while the final Rondo‘s march-like theme begins with folk-like simplicity, it soon becomes more virtuosic.
