Prone, propped on elbows. Count the half-cycles until the head settles.
Full Lesson Notes
Complete Practice
Prone, propped on elbows. Let the head hang heavy. Initiate a slow side-to-side oscillation of the skull, driven only by the alternating tone of the upper trapezius. Count the half-cycles until the head settles. Now repeat after softening the jaw, then after softening the tongue, then after softening the eyes. The change in number of half-cycles per twitch. The jaw is usually the largest damper; the tongue is the most surprising one. --- Challenge: The half-cycle count is small (probably 1-3), so the resolution of the experiment is coarse and may not cleanly distinguish jaw from tongue.
