Fantasy on Serbian Themes

Nikolai Rimsky-Korsakov wrote his Fantasia on Serbian Themes, Op. 6, in 1867. Mily Balakirev conducted the first performed of this piece in May of that year. It is also known as the "Serbian Fantasy".
The Fantasy was actually Balakirev's idea for the young Rimsky-Korsakov to compose. He requested the piece for a concert of pan-Slavonic music he had planned for May 24, 1867, programming his "Czech Overture" on the same billing. Balakirev also produced the Serbian themes for Rimsky-Korsakov to use in his composition. Rimsky-Korsakov confessed in his autobiography that it was not any feeling of nationalism or pan-Slavism that prompted him to write the "Fantasy", but the beauty of the themes themselves. Nevertheless, Balakirev liked the piece, which Rimsky-Korsakov had written rapidly.
A March 1868 review of the "Fantasy" by Pyotr Ilyich Tchaikovsky, in which he also mentioned Rimsky-Korsakov's First Symphony, found favour within the Balakirev circle. Tchaikovsky mentioned the symphony's "charming orchestration ... its structural novelty, and most of all by the freshness of its purely Russian harmonic turns ... immediately [showing] Mr. Rimsky-Korsakov to be a remarkable symphonic talent." Tchaikovsky was already acquainted with Balakirev and was working with him on his fantasy overture "Romeo and Juliet" The review opened the door for him to meet the other members of "The Five" face-to-face the following month.
In 1887 Rimsky-Korsakov revised the piece to prepare it for a new edition undertaken by Mitrofan Belyayev's publishing firm.
