The works of his youth are of a late-Romantic style. Between 1890 and 1894 (nine to 13 years of age) he wrote 31 piano pieces with corresponding opus numbers. He started numbering his works anew with "opus 1" in 1894 with his first large-scale work, a piano sonata in G minor ( Gillies 2001 ). Up to 1902, Bartók wrote in total 74 works which can be considered in Romantic style. Most of these early compositions are either scored for piano solo or include a piano. Additionally, there is some chamber music for strings. [ citation needed ]
Ginastera was an Argentinean composer who incorporated into his writing themes and rhythms from South America. He was a recipient of a Guggenheim fellowship and used that fellowship to study in the United States from 1945-1947. Although he did not write any pieces for beginning piano study, some of his pieces can be used for the later intermediate and advanced player. These pieces are 12 American Preludes (included in these preludes is a tribute to Copland and Villa-Lobos); Milonga; Rondo on Argentine Childrens Folk Tunes ; and Malambo.
