Excursions, Op. 20, is the first published solo piano piece by a composer born in what year?
Samuel Barber Samuel Osborne Barber II (March 9, 1910 – January 23, 1981) was an American composer of orchestral, opera, choral, and piano music. He is one of the most celebrated composers of the 20th century: music critic Donal Henahan stated that "Probably no other American composer has ever enjoyed such early, such persistent and such long-lasting acclaim."
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.
