Answer:
Musicals include every person's voice and their voices are incorporated in to one song that is trying to tell some form of a story. It wouldn't be a musical if there were one person right? So the "collaborative" part induces the fact that it is a musical with multiple roles for singing and acting. I hope this will help you, this answer came truly from me. Thank you.
life is something that is quite meaningless we are all born to live but we all die to live whats the point. Life is fun though and good we have our own little stories to be told and we share memories with the people we meet and love. we're born, we go to school, we work, we laugh, we cry, we die and everything in between. hope this helped have a great life ;)
