Silent while you rest; a plucked note each time arg F crosses one of five phase lines (D, E, F♯, A, B): a loop round a zero plays a rising scale, round a pole a falling one, and the low Ds count its turns. A closed loop sings its winding number as one note. Cuts, zeros and poles, contours
On iPhone and iPad, the ring/silent switch mutes these sounds.
Shift+M turns sound on or off; Esc stops any playback. On a focused plane: the arrows move a probe, Z finds the next zero or pole, O the order here, D describes the view, Enter draws a loop, L listens along it.
