Dwarves act in a more simpler way. See dwarves are high spirited and work really hard but depending on the situation they can get a little malicious. In the book when the dwarves were singing the content of the words were small in sized paragraphs. The tone seemed fairly joyful and pretty normal. Structure was joyful as well, but the dwarves were really just singing about what they were going to see so the words were kind of a mystery type of thing.
Elves act in a more spirited tendency. Their tone is really unmistakably cheerful.
