We use music therapy to "fix" a problem. And as versatile as music therapy is, we can remedy most problems. Which means that as music therapists we have to be very critical thinkers. We must be experts at applying music in creative ways.
This video is an example of a musically creative way to get more people to take the stairs over the escalator. What are some therapeutic benefits of this? Well, I thought 1) we know taking the stairs is better for us because we move more and this is good for our health, and 2) people commuting past these stairs may be in a happier mood for the rest of the day because walking on a piano is unusual and, well... fun.
Can you think of more therapeutic benefits?
