When I was making my music minister rounds in the hospital yesterday, I noticed that when I walk down certain hallways and corriders, my small lap harp begins to "sing" in my hand along with vibrations. Although I am sure this is due only to machinery and or heating and cooling systems creating a sympathetic resonance in the harp, I love the feel of the harp singing on it's own. And brings to mind the concept of the "Music of the Spheres" with the reality that we are all connected on a deep level. (Quantum physics has proved that!).
