For a while now, though, they've dangled from a low limb of the witch hazel tree, far enough out in the yard that the wind catches them, moves their string and clapper. When I'm out in the yard weeding or picking up sticks I hear their song.
The chimes have been restrung and refurbished several times, but I still remember unwrapping them, the little note that explained they were in the "happy key of D Major."
Is D Major a happy key? I've never minded it. Only two sharps. Not as easy as G Major (one sharp) or C Major (all white keys) but easier than A (three sharps) and E (four).
I did a bit of googling, learned that Franz Schubert called D Major the key of triumph and hallelujahs. That's good enough for me.
