Martin Bläse Brass Sound Bowl 6.75" x 2" 1lb 14oz Koshi Chimes These frequencies are generally safeMartin Blse sound bowls are unique in generating dual tonestwo frequencies separated by less than 10 Hertz. This close proximity causes interference patterns that produce a captivating vibrato or shimmering effect.

Unlike Nepalese and Tibetan bowls, which are fire forged, Martin strikes the metal without heat.
