Singing bowl tuner online
This singing bowl tuner shows the note, the octave and the frequency of your bowl, so you can label it, compare bowls or choose ones that sound well together.
How to use it
- Press Turn on microphone and allow access. Place the bowl on its cushion in a quiet room.
- Rim the bowl slowly and evenly, or strike it softly on the side.
- Read the note and the frequency once the sound is steady. The cents show how close it is to the nearest note.
- Repeat a few times: the reading that comes back every time is the bowl's main tone.
Help and explanations
A bowl gives several tones at once. Rimming with the stick usually brings out the lowest one, the fundamental; a strike also excites higher partials. The tuner follows the strongest tone, so try both ways and note which one you mean when you name the bowl.
Can a singing bowl be tuned?
Metal and crystal bowls keep their pitch; there is nothing to adjust. Adding a little water lowers the pitch slightly, which can help match two bowls, but it changes the sound too. To build a set, it is easier to choose bowls whose notes already fit together.
About 432 Hz bowls
Some bowls are sold as tuned to A432. The tuner can show this: set the reference A to 432 Hz in the settings and the cents will be measured against that scale.
Tips
- Hand-hammered bowls often sit between two notes; the cents tell you which one is closer.
- Note the frequency as well as the note: it is the most precise way to describe a bowl.
- Large bowls have low, quiet fundamentals; bring the phone closer for a steadier reading.
Frequently asked questions
How do I find the note of my singing bowl?
Rim or strike the bowl, wait for a steady sound and read the note and frequency. Repeat to confirm the main tone.
Why do I get two different notes?
Bowls have several partials. Rimming usually gives the fundamental; striking can make a higher partial dominate.
Can I check if a bowl is 432 Hz?
Yes: set the reference A to 432 Hz and see whether the bowl reads close to 0 cents on a note.
