A sand-cast brass singing bowl with a tuned fundamental of 432 Hz — the so-called verdi tuning, slightly warmer than the standard 440. The note sustains for nearly ninety seconds, long enough to bookend a sitting without a timer.
The bowl rests on a lathe-turned base of Aomori white oak, oiled with raw tung. The mallet is cherry wood with a wool-felt head, wrapped in waxed cotton thread.
Each bell is finished by hand: the rim is polished, the body left with the soft hammered texture from casting. A small mandala is engraved inside the base — visible only when the bowl is tipped.
