Marimba

Marimba players in Africa

Instruments like the marimba are present throughout the entirety of sub-Saharan Africa.[3] The instrument Itself is most similar and shares its name with the marimbas of modern-day Angola and the Democratic Republic of the Congo.[4] Although it is also similar to instruments that exist in West Africa such as the balafon of the Mandinka people, known as gyil among the Gur peoples in and around northern Ghana and Burkina Faso.[5]

"The Marimba" from "The Capitals of Spanish America" (1888)

The marimba is popular throughout Central America, with its popularity spreading from southern Mexico to Nicaragua. The first historical account in Central America is from 1550 where enslaved Africans in Guatemala are reported playing it. By 1680 accounts of Maya musicians using marimbas with gourd resonator were made in Guatemala. It became more widespread during the 18th and 19th centuries, as Maya and Ladino ensembles started using it on festivals. In 1821, the marimba was proclaimed the national instrument of Guatemala in its independence proclamation.[6]

Marimba's second range of popularity in Latin America is in the Pacific coast of Colombia and Ecuador.[7] The instruments were brought there via the African diaspora and their cultural significance has survived to the present day.[8] The Afro-Latino communities that take part in preserving and playing it value its importance as a touchstone of their resilience.[9]

In Colombia the most widespread marimba is the marimba de chonta (peach-palm marimba). Marimba music has been listed on UNESCO as an intangible part of Colombian culture.[10] In recent times marimberos (marimba players) and the marimba genres as a whole have started to fade out in popularity.[8] Nonetheless, the genre is still popular in the departments of Chocó and Cauca.[11]

An example of the Afro-Ecuadorian marimba esmeraldeña

In Ecuador the most widespread marimba is the marimba esmeraldeña (Esmeralda marimba).[12] Marimbas are an important aspect of Afro-Ecuadorian culture: many religious ceremonies and songs are accompanied with marimba music along with festivals and dances.[12] It is most popular in the province of Esmeraldas where in the 16th century Alonso de Illescas, a maroon, found a maroon settlement near the area around modern day Esmeraldas. In that province, it evokes a sense of pride for the community in which years centuries marimba music has been prohibited after government encroachment upon the Esmeraldas province.[13]

Marimbas have become widely popular around the world being used throughout Africa, South East Asia, Europe, North America, South America and Central America.[14]

In 1850, Mexican marimbist Manuel Bolán Cruz (1810-1863), modified the old bow marimba, by the wooden straight one, lengthening the legs so that the musicians could play in a standing mode, expanded the keyboard and replaced the gourd resonators by wooden boxes.

In 1892, Mexican musician Corazón de Jesús Borras Moreno expanded marimba to include the chromatic scale by adding another row of sound bars, akin to black keys on the piano.[15]

The name marimba was later applied to the orchestra instrument inspired by the Latin American model. In the United States, companies like J.C. Deagan and the Leedy Manufacturing Company company adapted the Latin American instruments for use in western music. Metal tubes were used as resonators, fine-tuned by rotating metal discs at the bottom; lowest note tubes were U-shaped. The marimbas were first used for light music and dance, such as vaudeville theater and comedy shows. Clair Omar Musser was a chief proponent of marimba in the United States at the time.

French composer Darius Milhaud introduced marimbas into Western classical music with his 1947 Concerto for Marimba and Vibraphone. Four-mallet grip was employed to play chords, enhancing interest for the instrument.[16] In the late 20th century, modernist and contemporary composers found new ways to use marimba: notable examples include Leoš Janáček (Jenufa), Carl Orff (Antigonae), Karl Amadeus Hartmann, Hans Werner Henze (Elegy for Young Lovers), Pierre Boulez (Le marteau sans maître) and Steve Reich.

Marimba bars may be made of either wood or a synthetic fiberglass material. For the best sound quality, rosewood is the most desirable, while padauk is a popular affordable alternative. Synthetic fiberglass bars are often sold under trade names such as Kelon (for Ludwig-Musser), Klyperon (for J.C. Deagan), or Acoustalon (for Yamaha), among others. Bars made from synthetic materials generally fall short in sound quality and generally have a longer decay in comparison to wooden bars, but they are often less expensive and yield added durability and weather resistance, making them suitable for outdoor use. For wooden bars, changes in humidity or temperature may alter the moisture levels within the wood. This may negatively affect the pitch and tonality of the bar.

Bubinga (Guibourtia demeusei) and mahogany have also been cited as comparable to rosewood in quality for use as marimba bars. The specific rosewood, Dalbergia stevensonii, only grows in Southern Guatemala and Belize, formerly the British Honduras.[17] This wood has a Janka rating of 2200, which is about three times harder than silver maple. The bars are wider and longer at the lowest pitched notes, and gradually get narrower and shorter as the notes get higher. During the tuning, wood is taken from the middle underside of the bar to lower the pitch. Because of this, the bars are also thinner in the lowest pitch register and thicker in the highest pitch register.

Marimba bars produce their fullest sound when struck just off center, while striking the bar in the center produces a more articulate tone. On chromatic marimbas, the accidentals can also be played on the extreme front edge of the bar, away from the node (the place where the string goes through the bar) if necessary. Playing on the node produces a sonically weak tone, and the technique is only used when the player or composer is looking for a muted sound from the instrument.

Contrabass marimba: range of G₁–G₃

Bass marimba: range of C₂–F₃

There is no standard range of the marimba, but the most common ranges are 4.3 octaves, 4.5 octaves and 5 octaves; 4, 4.6 and 5.5 octave sizes are also available.

• 4 octave: C₃ to C₇.
• 4.3 octave: A₂ to C₇. The .3 refers to three semitones below the 4 octave instrument. This is the most common range.
• 4.5 octave: F₂ to C₇. The .5 means "half";
• 4.6 octave: E₂ to C₇, one semitone below the 4.5. Useful for playing guitar literature and transcriptions.
• 5 octave: C₂ to C₇, one full octave below the 4 octave instrument, useful for playing cello transcriptions, e.g., J. S. Bach's cello suites.
• Bass range (varies, but examples range from G₁–G₃ or C₂–F₃)

The range of the marimba has been gradually expanding, with companies like Marimba One adding notes up to F above the normal high C (C₇) on their 5.5 octave instrument and marimba tuners adding notes lower than the low C on the 5 octave C₂. Adding lower notes is somewhat impractical; as the bars become bigger and the resonators become longer, the instrument must be taller and the mallets must be softer in order to produce a tone rather than just a percussive attack. Adding higher notes is also impractical because the hardness of the mallets required to produce the characteristic tone of a marimba are much too hard to play with in almost any other, lower range on the instrument.

The marimba is a non-transposing instrument with no octave displacement, unlike the xylophone, which sounds one octave higher than written, and the glockenspiel, which sounds two octaves higher than written.

PVC resonators

Part of the key to the marimba's rich sound is its resonators. These are tubes (usually aluminum) that hang below each bar.

In the most traditional versions, various sizes of natural gourds are attached below the keys to act as resonators; in more sophisticated versions carved wooden resonators are substituted, allowing for more precise tuning of pitch. In Central America and Mexico, a hole is often carved into the bottom of each resonator and then covered with a delicate membrane taken from the intestine of a pig to add a characteristic "buzzing" or "rattling" sound known as charleo.[18] In more contemporary-style marimbas, wood is replaced by PVC tubing. The holes in the bottoms of the tubes are covered with a thin layer of paper to produce the buzzing noise.

The length of the resonators varies according to the frequency that the bar produces. Vibrations from the bars resonate as they pass through the tubes, which amplify the tone in a manner very similar to the way in which the body of a guitar or cello would. In instruments exceeding 4+1⁄2 octaves, the length of tubing required for the bass notes exceeds the height of the instrument. Some manufacturers, such as DeMorrow and Malletech, compensate for this by bending the ends of the tubes. This involves soldering smaller straight sections of tubes to form "curved" tubes. Both DeMorrow and Malletech use brass rather than aluminium. Others, such as Adams and Yamaha, expand the tubes into large box-shaped bottoms, resulting in the necessary amount of resonating space without having to extend the tubes. This result is achieved by the custom manufacturer Marimba One by widening the resonators into an oval shape, with the lowest ones reaching nearly a foot in width, and doubling the tube up inside the lowest resonators—a process known as "Haskelling", originally used in pipe organ resonators, and named for its inventor, William E. Haskell.

Resonator tuning involves adjusting "stops" in the tubes themselves to compensate for temperature and humidity conditions in the room where the instrument is stored. Some companies offer adjustment in the upper octaves only. Others do not have any adjustable stops. Still some companies (Malletech and DeMorrow) offer full-range adjustable stops.

On many marimbas, decorative resonators are added to fill the gaps in the accidental resonator bank. In addition to this, the resonator lengths are sometimes altered to form a decorative arch, such as in the Musser M-250. This does not affect the resonant properties, because the end plugs in the resonators are still placed at their respective lengths.

An example of the mallets used when playing a marimba.

The mallet shaft is commonly made of wood, usually birch, but may also be rattan or fiberglass. The most common diameter of the shaft is around 8 mm (1⁄4 in). Shafts made of rattan have a certain elasticity to them, while birch has almost no give. Professionals use both depending on their preferences, whether they are playing with two mallets or more, and which grip they use if they are using a four-mallet grip.

Appropriate mallets for the instrument depend on the range. The material at the end of the shaft is almost always a type of rubber, usually wrapped with yarn. Softer mallets are used at the lowest notes, and harder mallets are used at the highest notes. Mallets that are too hard will damage the instrument, and mallets that might be appropriate for the upper range could damage the notes in the lower range (especially on a padouk or rosewood instrument). On the lower notes, the bars are larger, and require a softer mallet to bring out a strong fundamental. Because of the need to use varying hardnesses of mallets, some players, when playing with four or more mallets, might use graduated mallets to match the bars that they are playing (softer on the left, harder on the right).

Some mallets, called "two-toned" or "multi-tonal", have a hard core, loosely wrapped with yarn. These are designed to sound articulate when playing at a loud dynamic, and broader at the quieter dynamics.

The first solo marimba concerto, Concertino for Marimba, was composed by Paul Creston in 1940, after a commission by Frédérique Petrides. The Concertino for Marimba premiered on 29 April 1940 in Carnegie Hall with marimba soloist Ruth Stuber Jeanne and the Orchestrette Classique.[19]

The Oregon Symphony Orchestra commissioned Tomáš Svoboda to compose Concerto for Marimba and Orchestra, Op. 148, in 1995, was recorded in 2003 with Niel DePonte on marimba. The recording was nominated for the 2003 Grammy Award for Best Instrumental Soloist(s) Performance (with orchestra).[20]

The marimba is the most popular solo keyboard percussion instrument in classical music. Popular marimba solos range from beginner solos such as Yellow After the Rain and Sea Refractions by Mitchell Peters to more advanced works such as "Variations on Lost Love" by David Maslanka and "Rhythmic Caprice" by Leigh Howard Stevens.[21]
