Book excerpt: This is the complete sheet music for Pyotr Tchaikovsky's 1886 solo piano composition, “Dumka, Op.59”. This modern, high-quality edition is ideal for following and annotating the music, and it is not to be missed by collectors of classical music scores. Pyotr Ilyich Tchaikovsky (1840 – 1893) was a Russian composer during the late-Romantic period. Although his music was and remains popular, it originally received a mixed critical reception, with some Russian commentators feeling that it did not represent their native musical values. Conversely, prominent western critics also claimed that it did not follow western principles adequately. Despite this, Tchaikovsky's work is some of the most popular music in the classical repertoire. Classic Music Collection constitutes an extensive library of the most well-known and universally-enjoyed works of classical music ever composed, reproduced from authoritative editions for the enjoyment of musicians and music students the world over.
