The red coloured 14" model is aligned with the root chakra and tuned to the C note. In the 432 Hz version, however, the concert pitch A is not at the standard Western frequency of 440 Hz, but at 432 Hz. This tuning is said to have, among other things, a particularly relaxing and calming effect. However, this singing bowl does not harmonize with conventionally tuned instruments. It should be played either individually or together with other 432 Hz instruments - such as Sela Unity Handpans.
