Searle wrote his Piano Sonata, Op. 21 for a recital at the Wigmore Hall on 22 October 1951, given by the Australian pianist Gordon Watson to celebrate the 140th anniversary of the birth of Franz Liszt. (Watson also performed the complete "Transcendental Études" on that occasion.) The Sonata was loosely based on Liszt's Sonata in B minor and has been described as "probably, both the finest and most original piano work ever produced by a British composer".
