About this number

A crystal singing bowl tuned to C. This entry uses 256 Hz, which is C in scientific pitch. That is about 38 cents below C4 at A = 440 (261.63 Hz), a little over a third of the step between two neighboring piano keys. Crystal singing bowls are made from fused quartz. Manufacturers claim very high purity. They produce a pure, sustained tone with very few overtones compared to metal bowls. Sellers offer crystal bowls tuned to A = 440, where C4 is 261.63 Hz, or to A = 432, where C4 is 256.87 Hz.

What is said about it

What is said, not what was measured
