The kalimba Tuning Hammer is a useful tool that you can use to tune your kalimba or thumb piano. You can use it to strike the tines backwards or forwards alongside a tuning app on your mobile phone to get your instruments notes perfectly in tune. Without a Tuning Hammer you will be forced to push the tines with your fingers and this is far from ideal. This tuning hammer will allow you to spend more time creating melodies and less time tuning!
