Answer:
Music is an art form that can speak to anyone in the world, no matter their race, religion, culture, etc. It can bring people together on an emotional level and break down barriers between people. It can speak to people in a way that cannot be found anywhere else.
For the part of your question on raising awareness for a social cause, I would point to examples like "Do They Know It's Christmas?", "Imagine", and "We Are the World". All of these songs bring light to issues that were plaguing the world at the time and get the message to entire generations of people.
I believe the correct answer is: song cycle.
The collection of art songs, unified
by poet, narrative, musical style, or composer are called song cycle or program
music for instrumental music associated with story, poem, idea, or scene. First
song cycle was “Il Canzoniere” or “Rime Sparse” written by Italian humanist
poet Francesco Petrarca to his belove Laura.
