Odette is the central princess in Pyotr Ilyich Tchaikovsky's ballet Swan Lake, first performed in 1877, where she is cursed to live as a swan by day. Her image and music have become shorthand for tragic, graceful beauty in popular culture, appearing in films, animation and games that borrow the swan princess theme. This brief humming version strips the idea down to a single recognisable melody line, which is why it travels easily online as a standalone clip for edits, roleplay and fairytale references where a full orchestral excerpt would be too long.
