The mbira (pronounced m-BEER-ra , IPA (?)m'b?) is an African musical instrument, traditional to the Shona people of Zimbabwe. It consists of a wooden board (often fitted with a resonator) with attached staggered metal tines, played by holding the instrument in the hands and plucking the tines with the thumbs (at minimum), the right forefinger (most mbira), and sometimes the left forefinger. Musicologists classify it as a lamellaphone, part of the plucked idiophone family of musical instruments. In Eastern and Southern Africa, there are many kinds of mbira, often accompanied by the hosho, a percussion instrument. It is often an important instrument played at religious ceremonies, weddings, and other social gatherings.
Though an ancient instrument, it was commercially produced and exported by ethnomusicologist Hugh Tracey from the 1950s onward, popularizing the instrument outside Africa; Tracey's design was modeled after the mbira nyunga nyunga.
Mbira became popularized largely due to the success of Thomas Mapfumo in the 1980s, who included mbira on stage accompanying modern rock instruments such as electric guitar and bass, drum kit, and horns. Mapfumo's arrangements included numerous songs directly drawn from traditional mbira repertoire. Other notable influencers bringing mbira music out of Africa are: Dumisani Maraire, who brought marimba and karimba music to the American Pacific Northwest; Ephat Mujuru, who was one of the pioneer teachers of mbira dzavadzimu in the US; the writings and recordings of Zimbabwean musicians made by Paul Berliner.
Erica Azim is a notable contemporary influencer as the director of MBIRA the non-profit, dedicated to preserving and recording traditional mbira dzavadzimu in Zimbabwe.
Joseph H. Howard and Babatunde Olatunji have both suggested that mbira (and other metal lamellaphones) are thoroughly African, being found only in areas populated by Africans or their descendants. Similar instruments were reported to be used in Okpuje, Nsukka area of the south eastern part of Nigeria in the early 1900s.
Various kinds of plucked idiophones and lamellaphones have existed in Africa for thousands of years. The tines were originally made of bamboo but over the years metal keys have been developed. The mbira appears to have been invented twice in Africa: a wood or bamboo-tined instrument appeared on the west coast of Africa about 3,000 years ago, and metal-tined lamellophones appeared in the Zambezi River valley around 1,300 years ago. These metal-tined instruments traveled all across the continent, becoming popular among the Shona of Zimbabwe (from which the word mbira comes) and other indigenous groups in Zimbabwe and Mozambique. The mbira differentiated in its physical form and social uses as it spread. Kalimba-like instruments came to exist from the northern reaches of North Africa to the southern extent of the Kalahari Desert, and from the east coast to the west coast, though many or most groups of people in Africa did not possess mbiras. There were thousands of different tunings, different note layouts, and different instrument designs, but there is a hypothetical tuning and note layout of the original metal-tined instrument from 1,300 years ago.
In the mid 1950s the mbira was the basis for the development of the kalimba, a westernized version designed and marketed by the ethnomusicologist Hugh Tracey, leading to a great expansion of its distribution outside Africa.
Lamellophones are instruments which have little tines, or "lamellae", which are played by plucking. Unlike stringed instruments or air-column instruments like flutes, the overtones of a plucked lamella are inharmonic, giving the mbira a characteristic sound. The inharmonic overtones are strongest in the attack and die out rather quickly, leaving an almost pure tone. When a tine is plucked, the adjacent tines also create secondary vibrations that increase the harmonic complexity of an individual note.
Mbira music, like much of the sub-Saharan African music traditions is based on cross-rhythm. An example from the kutsinhira part of the traditional mbira dzavadzimu piece "Nhema Musasa" is given by David Peñalosa, who observes that the left hand plays the ostinato "bass line," while the right hand plays the upper melody. The composite melody is an embellishment of the 3:2 cross-rhythm (also known as a hemiola).

It is common on African mbira and other lamellophones to have the lowest notes in the center with higher notes to the far left and the far right--this is an ergonomic nicety, in that the thumb can pivot such that all the tines are easy to reach. However, traditional African tunings use notes that do not lie on the grid of the Western tempered scale, and traditional mbira note layouts are often idiosyncratic, sometimes with adjacent tines making part of a scale, but then an odd note thrown in that defies the pattern.
Historically, mbira tunings have not mapped exactly onto Western scales; it is not unusual for a seven-note sequence on a mbira to be "stretched" over a greater range of frequencies than a Western octave and for the intervals between notes to be different from those in a Western scale. Tunings have often been idiosyncratic with variations over time and from one player to another. A mbira key produces a rich complex of overtones that varies from one instrument to another depending on its maker's intentions and accidents of fabrication, such that some instruments simply sound better when some notes of a familiar tuning are pushed. With the increased popularity of the mbira in North America, Europe, and Japan in recent decades, Zimbabwean mbira makers have tended to tune their instruments more uniformly for export, but much variation is still found among mbira in their homeland.
Tunings vary from family to family referring to relative interval relationships and not to absolute pitches. The most common tuning played throughout Zimbabwe and among non-Zimbabwean mbira players worldwide is Nyamaropa, similar to the western Mixolydian mode. Names may also vary between different families; Garikayi Tirikoti has developed a "mbira orchestra" that has seven different tunings, each starting on a different interval of the same seven-note scale, where it is possible to play all instruments in a single performance. The seven tunings that Garikayi uses are: Bangidza, Nyabango, Nhemamusasa, Chakwi, Taireva, Mahororo, and Mavembe (all of which are also names of traditional songs save for Mavembe and Nyabango). The closest to what is commonly named "Nyamaropa" is his "Nhemamusasa" tuning.
Common names for tunings are:
In Shona music, the mbira dzavadzimu ("voice of the ancestors", national instrument of Zimbabwe) is a musical instrument that has been played by the Shona people of Zimbabwe for thousands of years. The mbira dzavadzimu is frequently played at religious ceremonies and social gatherings called mabira (sing. "bira").
A typical mbira dzavadzimu consists of between 22 and 28 keys constructed from hot- or cold-forged metal affixed to a hardwood soundboard (gwariva) in three different registers--two on the left, one on the right.
While playing, the little finger of the right hand is placed through a hole in the bottom right corner of the soundboard, with the little finger entering from the front of sound board, and the ring finger and middle finger reaching around the back to stabilize the instrument. This leaves the thumb and index finger of the right hand open to stroke the keys in the right register from above (thumb) and below (index finger). The fingers of the left hand stabilize the left side of the instrument, with most fingers reaching slightly behind the instrument. Both registers on the left side of the instrument are played with the left thumb. Some mbira possess an extra key in the upper left register which is hit from below by the left index finger.
Bottle caps, shells, or other objects ("machachara") are often affixed to the soundboard to create a buzzing sound when the instrument is played. In a traditional setting, this sound is considered extremely important, as it is believed to attract ancestral spirits.
The mbira dza vadzimu is very significant in Shona religion and culture, considered a sacred instrument by the Shona people. It is usually played to facilitate communication with ancestral spirits, bringing the spirit of the dead back on its homestead. Within the Shona tradition, the mbira may be played with paired performers in which the kushaura, the caller, leads the performed piece as the kutsinhira, the responder, "interlocks" a subsequent part. The ritual is known as the Bira. During these all-night ceremonies, people call upon the spirits to answer questions. The variations of notes in an Mbira piece aid the participants in going into trance, which in Shona culture aids the spirits in taking over the participant's body.
The nyunga nyunga which normally has 15 keys, originated from Manicaland where it traditionally played the entertainment role during social gatherings and commemorations. Jeke (Jack) Tapera introduced the mbira nyunga nyunga in the 1960s from Tete province of Mozambique to Kwanongoma College of African music (now United College of Music) in Bulawayo. Two keys were then added to make fifteen (Chirimumimba, 2007), in two rows. The mbira nyunga nyunga is similar in construction to the mbira dzavadzimu, but has no hole in the soundboard. Key pitch radiates out from the center, rather than from left to right.
Zimbabwe's Dumisani Maraire originated mbira nyunga nyunga number notation. The upper row keys (from left) are keys 2, 4, 6, 8, 10, 12, and 14 while the bottom row keys are notated as 1, 3, 5, 7, 9, 11, 13, and 15. Maraire brought awareness of this instrument to the United States when he came to the University of Washington as a visiting artist from 1968-1972.
Recently a Midlands State University (Gweru, Zimbabwe) lecturer in the department of music and musicology has suggested a letter notation; the upper keys as (from first left upper key) E, D, C, F, C, D, and E and the lower or bottom keys as (from the first lower key) A, G, F, A, F, C, D, and E. But the Maraire number notation has remained the internationally accepted system (Chirimumimba, 2007).
Njani mbira has 30 to 32 keys and was also originated from Zimbabwe particularly Masvingo and Makonde.
The nhare has 23 to 24 keys and was originated from Zimbabwe. In the Zimbabwean tradition, nhare was used for rituals of communicating with Musikavanhu or Nyadenga (God).
Mbira matepe which has 26 keys originated from along the borders of Zimbabwe and Mozambique.
The Hugh Tracey kalimbas are tuned diatonically in the key of G. The arrangement of the notes on the Hugh Tracey kalimba borrows from the typical scheme with the lowest notes in the center and the upper notes on the left and the right, with the notes in the ascending scale alternating strictly right-left and going outwards towards the two sides.
The diatonic western kalimba tuning which Tracey used was practical for a worldwide instrument--with hundreds of African kalimba tunings, the chosen Western standard would maximize the number of people who would immediately connect with the kalimba. The practicality of this note arrangement, with notes going up the scale in a right-left-right-left progression, is that modal 1-3-5 or 1-3-5-7 chords are made by playing adjacent tines. If chords are played in the lower octave, the same notes will appear on the opposite side of the kalimba in the upper octave, which makes it very easy to simultaneously play a melody in the upper octave and an accompanying harmony in the lower octave. So, the arrangement of notes on the Hugh Tracey kalimba (and on virtually any kalimba that copies the instrument) makes certain complex musical operations very simple.
Alternative tunings are possible, as the tines of most kalimbas are easily pushed in and out to sharpen or flatten their pitch. Some alternative tunings simply change the key of the kalimba, without changing the note layout scheme. Other alternative tunings move the kalimba to non-modal scales (such as Middle-Eastern scales). Each note of the kalimba can be tuned independently (unlike a guitar), so any scale, western or non-western, is possible, and traditional African scales are still accessible to this modern African instrument. Composer Georg Hajdu has tuned the Hugh Tracey alto kalimba to the chromatic steps of the Bohlen-Pierce scale in a piece called Just Her--Jester--Gesture. The Bohlen-Pierce scale subdivides the just twelfth into 13 steps.
