Can you guess the music?

The start of the music was loud and sounded like the army marching towards the tower. When the army lined up the King and Queen came through the gate towards the castle. There were lots of trumpets, drums and violins and made it sound dramatic like something special was going to happen. Then the music changed and sounded low, like there was someone trying to sneak into the castle. The secret agent for the bad guys followed the King and Queen. The king turned around and started to chase the secret agent the music sped up and when the King caught him he put him in the deep dark dungeon. After the King caught the secret agent he felt dizzy and tired and fell in a daze, the music was slow and woke up in darkness.
