He supported Tchaikovsky financially at the beginning of his career. At times, Jurgenson held the worldwide rights for Tchaikovsky's compositions. The piano piece „Mazurque pour danser“, No. 6 of the Eighteen Pieces op. 72 (1892) is dedicated to Osip's daughter Luiza.
Tchaikovsky is considered the most important composer of the 19th century in Russia, although he did not belong to the Group of Five. Tchaikovsky continued Anton Rubinstein's school, which was influenced by Western music. Tchaikovsky's best-known compositions include his last three symphonies, the violin concerto, his first piano concerto, the 1812 overture, and his opera „Eugene Onegin“. With „Swan Lake“, „Sleeping Beauty“ and „The Nutcracker“, he also wrote three of the most famous ballets in music history..
