![]() However, there are a few general guides when it comes to identifying a singing bowl’s frequency. Furthermore, the physical environment can also complicate a frequency reading because extreme temperatures can affect the reading.īecause of these circumstances, assigning a singing bowl a completely accurate static frequency is pretty difficult. Playing the lip of the singing bowl will create different vibrations than playing the side of the bowl. A tap high on the side wall will create different waves than a low tap on the side wall. The areas of the singing bowl that are being played also change the measured frequency. Generally, Hz readings for singing bowls are approximate due to the complexity of their sounds and changing frequencies as they switch between different tones and octaves. Singing bowls have a frequency range anywhere between 110 Hz and 660 Hz but can reach up to the 800s or even 900s. For a little perspective, the range of human hearing is from about 20 to 20,000 Hz according to Scientific American. Frequency is typically expressed in the unit Hertz (Hz). Sometimes, frequency is referred to as “pitch.” To determine the frequency of a singing bowl, you must measure the vibration of the bowl while it is being played. ‘Frequency’ is the number of cycles, or “speed”, of vibrations undergone during one unit of time. Singing bowls can produce several different frequencies. The sounds produced by singing bowls can contain multiple harmonics or dominant tones, which we will discuss below.įor a more detailed discussion explaining how singing bowls create sound, see our blog post on the science of singing bowls. We can both hear, and feel, these vibrations. As you strike the bowl or rub the rim with a mallet, the friction that results is what creates the vibrations. An idiophone is an instrument that “produces sound primarily by physical vibrations of the actual instrument.” In other words, the vibration of the bowl as it is being played is what produces sound. According to, singing bowls are idiophones.
