Respuesta :

The second theme is different from the opening theme because it's in a major key.

This difference allows:

  • The sound in the second theme presents a more serious and striking nature.
  • This increases the drama and allows for more attention from the listeners.
  • This change allows for more emotional content, which is gradually increasing, allowing for greater dynamism in the music.

In this case, we can say that the change in Key is performed at an opportune moment to catch the listener's attention and direct the rest of the melody.
