The Polovtsian Dances is a set of dances accompanied by a choir located in the second act of Alexander Borodin's opera "Prince Igor". The name could refer to the Coumans, called "Polovtsy" by the Rus. The music of the Polovtsian Dances is also played in concert where the instruments replace the voices. The first piano concerto was originally dedicated to Nikolai Rubinstein. But he thought the score so bad that he said it was nauseating.

Deeply shocked, we know the natural hypersensitivity of Tchaikovsky, the composer changed the dedication to the benefit of Hans von Bülow thanks to whom the concerto quickly acquired an immense reputation that still accompanies today. For his part, Rubinstein was forced to recognize the value of the score. The two men recognized their errors of judgment. Rubinstein also became one of the best performers and this concerto was one of his favorite works, his centerpiece.

Symphony No. 9 in E minor, B. 178 (Op.95) "From the New World" was composed by Antonín Dvořák in 1893 and performed on December 15 of the same year at Carnegie Hall by the New York Philharmonic Orchestra under the management of Anton Seidl. She is best known for her symphonies and one of the most popular works of the modern symphonic repertoire.
