In the Pjotr Sapegin's Madama Butterfly animation, they music played a major role in delivering the feelings of the secenes. The story begins when a lady meets a ship captain who have docked his ship on their island. They fell in love and we're happy together, the music was full of excitement and high tunes. Until the time when the captin had to leave, and go back to his home. A sad and dull music was playing on, as she struggles with him leaving. Then she finds out that she got pregnant, and enjoy her pregnancy and raising her daughter.
  One day the she saw the ship coming towards the island, the whole atmosphere filled with excitement again. The captin came back, but he wasn't alone. He came and brought his new wife along, and rookie her daughter away. The lady was shocked and devestated, saddness and bitterness took over her. As result she took her own life by taking herself apart.
    The story's up and downs went with the music, and it helped in preserving the situation. I think the music and the story went great with each other.
