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?"
Allegro moderato from Act II (this number later became the famous Dance of the Little Swans)
But do you know that there is an original "Dance of the Little Swans: Moderato" at the Act IV ?
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".
