I was recently in a hospital when a delicate melody played for a moment over the intercom system. A nurse explained that every time a baby is born they play music so everyone in the facility can enjoy the moment. (If a child is born overnight, they smartly wait and play the music in the morning.) Such an affirmation of life and joy.
It got me thinking of other sounds that collectively help us share a moment.
In Tacoma, WA, a man steps onto his deck and plays taps each night at sunset out of respect for those serving in the military.
