The sinking is the letting-go, and the image draws it in light, not harmony. The weave stays anchored on spring green (A). Two-thirds of the way through, the brightness falls from 6,665 hertz to near 1,000, and near the lower edge the weave opens: bare single threads over black, 'hit the bottom' engraved on the rings where the song touches it. The loudest moment comes just past the bottom, on the turn back up. Escape.
