The Tibetans were the first ones to be using singing bowls dating back to more or less a thousand years ago. Some people compare how Tibetan singing bowls look like and they assume that they are the same with the bowls that date back 3,000 years ago in India and Asia. In Tibetan culture, the singing bowls have been found to be used by shamans when they were doing their rituals.
For the past thousands of years, various kinds of metals were combined to make these singing bowls; some could go as low as five metals while some could go as high as using nine different metals. In the past, the metals that were used included silver, mercury, iron, gold, tin, and copper. Even so, it was determined in the past that the most common singing bowls included having some meteorites in them.
The most recent singing bowls that are made of metal are now being made by more or less the same kinds of metals that were used in the past by the Tibetans. Yet, the singing bowls in the present times that are made of metals are now coming with casts in order for them to look and sound the same so that you will not be having a hard time relearning what each singing bowl will be able to make sounds of in more ways than one. If price is not a factor for you, then you can always get the antique singing bowls if you are more after getting a feel of the Tibetan culture every time you will be using these singing bowls.
If you are more after personalization of your singing bowls, you can get them in crystal singing bowl materials that will let you choose what you want it to be made in the best possible way. You can also get crystal singing bowls that are made of composite materials; however, having singing bowls with the same sound is just useless in terms of the singing bowl that you are using.
For instance, if you are after ensuring that you achieve some meditation, you can buy yourself singing bowls as these tools have been shown to effectively let people reach this point in their meditation life. Having used singing bowls will be great in your goal of ensuring that you will be able to meditate as just hearing its high pitched sound will take you to certain places that you can never imagine.
Singing bowls are not that hard to use; they come with straight edges that can be used for your meditation with the help of a singing stick that you will be using at the edge of your bowl while you are rotating it at speeds that are just slow. Singing bowls can also be used for people who are doing yoga as this can help them meditate much deeper.
