A small musical interlude

This remarkably beautiful video, uploaded to YouTube one day before the Tōhoku earthquake and tsunami, turns out to be an ad for Sharp’s SH-08C telephone. It is, nonetheless, worth watching: in a tranquil forest, a single wooden ball rolls down a stepped wooden ramp, continuously, for two minutes. At each step, it falls and strikes a wooden bar tuned to play a single note of the 10th movement of Bach’s Herz und Mund und Tat und Leben, BWV 147, known in English as Jesu, Joy of Man’s Desiring. Interesting how they handle the sustained notes.
