I've bought an instrument but I'm not sure what note it is. What's the best way to find out?

We recommend InsTuner for your device. You can find many other free options by searching for "free instrument tuner" or "free chromatic tuner" at your mobile app store. These will give you an accurate reading of what note you are playing. For bowls, tap the rim (do not play around the rim) when calculating the note/frequency.
