Hi! I`m Pyotr Ilyich Tchaikovsky, the composer of Romanticism music era.
It`s so pleasant You are interested in my music at XXI.
"Where have you gone, o golden days of my spring?"
Oops... Its not a mistake!
The original name of this music is "Act IV. No. 27 Dance of the Little Swans: Moderato"
But all over the world "Allegro moderato" (from Act II, No. 13 Dances of the Swans) is known as the "Dance of the Little Swans".
