By far the most important thing you can do to keep your instrument in good condition is to tune your instrument regularly. This is of course is very pleasant for yourself, but it is also important for the life of your instrument. If people tell you that this instrument does not have to be tuned, do not believe them. Everything needs maintenance, every musical instrument, including your mbira or kalimba.
It is quite a challenge to have these instruments sound as they should sound, you want your instrument to sound like when you heard it for the first time. It is a matter of making very small adjustments, and constantly watching and listening to see if each key sounds right or wrong. This process means that you might have a good sounding instrument again within 5 minutes. In some cases it can take longer if, for example, the instrument has fallen and multiple keys are out of tune.
After all, each key must be in exactly the right place to give the resonance and the correct pitch. Tuning your instrument is a matter of practicing, practicing and practicing again. It is difficult to get the pitch of all the keys correctly the first time. This requires practice, so do not be afraid if it does not work immediately. But try again.

Two important things in the correct tuning of your Kalimba or Mbira
Firstly, you need to know at which pitch you want everything to be tuned. In what tuning is the instrument built and what is the pitch of each key? This is important to know when buying, as this is fixed on most kalimba and mbira instruments and cannot be changed after purchasing the instrument.
Secondly, you must have the right tools and place them in the right position when tuning to ensure you are not damaging your instrument. If it is your first time, get someone experienced with kalimba/mbira tuning to assist you.
