Name of Music (Possible Spoiler).

What was the name of the music for the dance in this movie? My sister thought it might be ethereal music. I was wondering about the "name" of the music for the dance in this movie, also. Not just the form of music ("Rock and Roll," "Ethereal," "Pop Music," et cetera are all forms of music), but also the name. Does someone have information about the name and about the "form" of music? Is it also ethereal for the "form" of music? I might also want the name of the music in addition to the "form" of music. The web page follows with the scene:

Thank you for the help. I want information with the reference to the music. I think that music may be enjoyable. Thank you, again.
