Does Music Help Create Community?

A few weeks ago, we received a letter from a potential donor who did not feel that music was a vital part of what makes up community.  My heart had an irregular beat as I was hit with the devastation of that misconception.  Music is, indeed, a vital part of what makes up community. Music is an avenue for expressing the deepest emotions of the soul. Happiness or sorrow are expressed through music.  Whatever the event, there is usually music to help create the mood for that event.  Music can even be the back drop or the focal point of an event.  Today, music is used as therapy for members of the community to aid in easing pain, lifting states of depression, improving the mental functioning of Alzheimer patients, etc.

Where would the world be without the expression of emotion through music?  How has music helped to create a sense of community in your sphere?
