Erica Azim answers your questions about mbira — the music, the instruments, the people, and the cultural traditions behind them. Questions about this website and the MBIRA non-profit organization are also welcome. If Erica doesn’t know the answer to your question, she’ll ask one of her many Zimbabwean mbira player friends and relay their answer.

That’s 3 questions!
1. Over time, the wood board of an mbira becomes darker from exposure to light, the natural oils on the hands of the musician, and sometimes dust/dirt. The keys become darker due to corrosion, and the different types of steel used by different makers vary in how quickly this happens.
2. It is important NOT to oil the board of an mbira, which could make the keys pop out when played, instead of staying in place. No routine upkeep is needed other than occasional tuning and tightening of keys. But some musicians use Vaseline on their thumbs/finger when playing, which also polishes the playing end of the keys, making them smoother and less likely to cause blisters when playing all night. Others may rub thumbs on their nose or forehead in order to use natural oils for the same purpose. Mbiras sold at mbira.org have Vaseline rubbed on the keys below the crossbars to prevent corrosion while stored in a coastal environment in California. Again VERY important NOT to put Vaseline on the keys at or above the crossbars, as it might leak down to the wood and result in keys popping out.
3. Mbira players typically travel with the mbira in a deze, which also protects it from the elements. However, in 1974 I once saw Ephat Mujuru scold a member of his mbira group who had his mbira in a clamp on the back of his bicycle, exposed to the rain which was starting.
For those who haven’t seen an older mbira yet, these are the mbiras of the Dzapasi Mbira Group.
Mbira-type instruments throughout Africa have many configurations and numbers of keys. The type of Shona mbira in Zimbabwe that is primarily discussed on this website most commonly has 22 to 24 keys, but sometimes up to 28 or even more according to the musician’s preference. Learn more about this at The Mbira Instrument.
A gwariva is the hardwood mbira soundboard that we hold in our hands and to which the metal keys are fastened. The word gwariva may also be used to refer to the whole mbira instrument.
An mbira tuning is the set of relationships between the notes of an mbira. Each mbira instrument typically has one tuning for its lifetime, set by the lengths, thicknesses, and positions of the keys held down on the bridge by the pressure bar. We tune an mbira by tapping the out of tune key from one end or the other.
There are many standard tunings and any number of idiosyncratic variations set by individual musicians and groups. Nyamaropa tuning is the most common tuning, but is found in infinite different pitches around Zimbabwe. The intervals on a nyamaropa, or “straight,” tuning mbira, are similar to Mixolydian mode in Western music, but have many slight variations as they are not tuned to Western half and whole steps in most cases.
