What nationality was the composer who wrote 'The First Piano Sonata in 1946'?
Piano sonatas (Boulez) Pierre Boulez composed three piano sonatas. The First Piano Sonata in 1946, a Second Piano Sonata in 1948, and a Third Piano Sonata was composed in 1955–57 with further elaborations up to at least 1963, though only two of its movements (and a fragment of another) have been published.
Piano Sonata Hob. XVI/49 The Piano Sonata in E-flat major, Hob. XVI/49, L.59, was written in 1789/90 by Joseph Haydn. It marked the beginning of Haydn's late, mature style with frequent use of alternation between staccato (mostly) and legato (often/sometimes). The transitions were much smoother compare to his early and middle works, with larger first and second movements, and a smaller third movement.
