Noise struck into a bell tone at 256, 384 and 512 Hz, ringing out over nine seconds

Tibetan Bowl is a singing bowl struck once every nine seconds: a quick bright onset, a long shimmering decay, and a soft tail that lingers until the next strike. The very high filter Q gives it a clear ringing pitch, a C and its fifth and octave, so it sounds like metal rather than air.
The color is 3.2, a little warmer than pink. Resonant filters at 256, 384 and 512 Hz with a Q of 40 and 40 percent mix produce the bell. The envelope attacks in 0.1 seconds, decays over 2 seconds to a low 30 percent sustain, holds for 3 and releases over 4, so each strike rings for about nine seconds before the next.
It is used for meditation timing, yoga transitions and as a gentle wake-up tone. Wind Chimes uses the same struck idea with higher, major-chord pitches and a faster cycle, and Resonant Drone sustains a lower tone instead of striking it. At low volume it is unobtrusive enough to run through an entire sitting without pulling focus.
