When I was lying in bed this morning, I saw this image in my mind. At first I called it a tuning bar, but when I looked up the image online, it was a tuning fork: a small steel instrument with two prongs, which when struck sounds a certain fixed tone in perfect pitch; used as a guide in tuning instruments, in testing hearing, etc.
I have two areas in life that need to be tuned. They developed early in life and now that I painted and wrote about them, this will bring me back to hearing the perfect tone.
