Valse des Alouettes from Harlequinade by Riccardo Drigo

Happy World Ballet Day! Although most of Harlequinade involves commedia dell'arte characters, this excerpt is the Waltz of the Larks. Apparently, the birds are feeling well-rested and content, as any ballet aficionado should be on this day.
The Royal Academy of Dance set its Advanced Foundation Rises to this music.
