Modern interpretation of the Tibetan Singing Bowls The Sela Crystal Singing Bowl Chakra Set Lotus 432 Hz includes seven crystal singing bowls with diameters ranging from approximately 20 cm (8" model) to approximately 36 cm (14"). The Crystal Singing Bowls are made of quartz crystal and have a chic frosted glass design with a rough white surface and a colored lotus design. The material used is given excellent sound properties by a special manufacturing process in which glass is melted down and formed into the desired shape by a centrifuge. Crystal singing bowls, like the traditional variants made of bronze or brass alloys, produce spherical, long-lasting sounds with a powerful fundamental tone and "singing", harmonic overtones. In direct comparison, the modern variant made of glass sounds even somewhat clearer and significantly longer than its metallic counterpart. Tuned to the seven main chakras The bowls in this set are matched both in color and sound to the seven energy centers of traditional chakra teaching and include the notes B, A, G, F, E, D and C (from the smallest to the largest model). The concert pitch A is not on the western standard frequency of 440 Hz, but on 432 Hz. This slightly lower pitch is said to have a relaxing and calming effect, among other things. This makes the Crystal Singing Bowl Chakra Set Lotus particularly suitable for meditation as well as for sound massages and therapeutic purposes, as the harmonic voice of the singing bowls can help to reduce stress and bring body and mind into harmony. Of course, the set is also suitable for taking listeners on a multi-layered musical sound journey. However, when playing with other instruments, make sure that they are also tuned to 432 Hz - such as our Sela Unity Handpans. With mallets and other accessories The Sela Crystal Singing Bowl Chakra Set Lotus comes with three mallets that have been specially designed for use with crystal singing bowls.
