Tchaikovsky's Piano Trio Op. 50 was composed in memory of his friend, the pianist and conductor Nikolai Rubinstein, who had died at age 45.
Dvořák composed his Piano Trio Op. 65 in F minor in the early months of 1883, shortly after the death of his mother, which is reflected in its tragic tone.
The finale of Dvořák's Piano Trio Op. 65 features a furiant, a Czech dance in triple meter with characteristic cross-rhythms, showcasing his Bohemian roots.
Tchaikovsky initially disliked the piano trio formation, writing to his patron Nadezhda von Meck that he found the different timbres of the instruments to 'battle one other'.
Nikolai Rubinstein, the dedicatee of Tchaikovsky's trio, founded the Moscow Conservatory in 1866 and recruited Tchaikovsky to teach harmony and music theory there.
Tchaikovsky's Piano Trio Op. 50 is his only work written for this combination of instruments and features a monumental two-movement structure, unusual for a trio.
