Dance of Four Little Swan is the fourth piece of music in the second act of Pyotr Il'yich Tchaikovsky dance drama Swan Lake. In the ballet Swan Lake, Aogueta, the white swan princess, agreed to the prince's courtship and made an everlasting vow. Four cygnets beamed and danced impromptu. So there was this "dance of four little swans". Dance of the Four Little Swan is reproduced with the most typical A, B and A'. Section A mainly uses woodwind instruments to play the theme. Under the background of the dominant and dominant tones composed of cello and bassoon, the two oboes play a light and lively tune in parallel three times, with full harmony and strong voice. When the music is played repeatedly, it looks brand-new because it is played by flute and clarinet. Section (b) is mainly played by stringed instruments, and the rhythm is more dynamic and interesting. Reproduce the music in paragraph (a'), return to the original simple and elegant style, and finally end the whole piece in orchestral performance. The whole song is a household name, popular and cordial, and the music and dance are integrated and fascinating. Because of its distinctive personality and appropriate image, this piece of music has become an instrumental sketch that performers can't put down and a ballet sketch that dancers often perform.
