Agogô

Overview

The agogô is a West African idiophone — a hand-held metal bell, or pair of bells, struck with a wooden stick to produce a clear, pitched, ringing tone. In its original Yoruba context the agogô is an essential ceremonial instrument; in its Brazilian context, brought across the Atlantic during the slave trade, it is the highest-pitched melodic voice in samba and one of the central instruments of the Candomblé religion.

The instrument is one of the simpler members of the percussion family — no membrane, no moving parts, no tuning mechanism — but its role in two major living musical traditions on opposite sides of the Atlantic gives it disproportionate cultural weight.

Origin & History

The agogô originated among the Yoruba people of present-day southwestern Nigeria and Benin, where it has long been used in religious ceremony, in court music, and in everyday social music. The Yoruba word agogô means “bell.” The single-bell and double-bell forms both exist in the West African tradition, with the double bell — two bells of different sizes attached by a curved metal handle — being the form most familiar today.

The Metropolitan Museum’s collection broadens the West African picture. A 19th-century Cameroonian double bell (MET object 502187) in iron is structurally a close cousin of the Yoruba agogô. A 19th-century Congolese single bell (MET 502268), also in iron, represents another West-Central African branch of the same broad metal-bell family. Both sit in the museum’s Musical Instruments department.

The agogô crossed the Atlantic with enslaved West Africans during the 17th and 18th centuries and became established in northeastern Brazil, particularly in Bahia. There it embedded itself in two parallel traditions: the African-derived Candomblé religion, where it remains one of the central ceremonial instruments, and the secular dance music that eventually became samba. By the 20th century the agogô was a fixture of Rio de Janeiro carnival samba schools and of countless smaller percussion ensembles throughout Brazil.

Construction & Materials

The Hornbostel-Sachs system places the agogô in 111.242 (sets of bells). The bells are forged or cast from iron (in the African tradition) or steel (in the modern Brazilian tradition), each shaped as a hollow conical or pyramidal cup with a closed top and an open mouth. In the double-bell form the two bells are joined by a curved metal handle that the player grips with one hand.

The two bells in a Brazilian double agogô are tuned to different pitches, normally a minor third or fourth apart, and the difference is inherent to the instrument — they are not adjusted by the player. The strike stick is a slim wooden dowel, sometimes wrapped at the striking end with cord or rubber for a softer attack.

How It’s Played

The player holds the double-bell instrument in one hand, gripping the curved metal handle, and strikes the bells with a wooden stick held in the other. Squeezing the handle pushes the bells together momentarily and dampens the ring; releasing the handle lets the bells ring freely. This dampening is part of the instrument’s expressive vocabulary.

In samba the agogô plays a continuous syncopated pattern that interlocks with the surdo (large bass drum), the tamborim (small frame drum) and the cuíca (friction drum) to produce the distinctive samba groove. In Candomblé the agogô plays specific rhythmic patterns linked to particular orisha (deities), and a knowledgeable listener can identify which orisha is being invoked by the agogô pattern alone.

Cultural Significance

The agogô’s cultural weight is greatest in two settings: Brazilian Candomblé religious ceremony and the carnival samba schools of Rio de Janeiro and Salvador. In Candomblé it is one of the small set of instruments — alongside the atabaque drums — that are considered sacred and are required to be present in any major ceremony. Apprentice agogô players in a Candomblé terreiro may study for years before being permitted to play in formal ceremony.

In samba the agogô is the highest pitched of the percussion section’s voices and provides the bell-like melodic counterpoint that floats above the rest of the ensemble. In carnival school competition, the agogô section’s clarity and tightness contribute directly to the school’s score.

Notable Examples & Recordings

The MET’s two African bells (objects 502187 and 502268) document the West and West-Central African ancestors of the modern Brazilian agogô. For listening, samba school recordings from Rio de Janeiro carnival — particularly by schools such as Mangueira and Beija-Flor — feature the agogô prominently. Naná Vasconcelos’s recordings span both traditional Bahian and contemporary jazz uses of the instrument. Field recordings from Bahia in the Smithsonian Folkways archive document Candomblé performance.

• Gankogui – the Ewe (Ghana) double bell, structurally identical to the West African agogô
• Cowbell – the Latin percussion equivalent in Cuban and Puerto Rican music
• Surdo – the large Brazilian bass drum that anchors samba
• Tamborim – the small Brazilian frame drum that interlocks with the agogô

Where to Hear It

Rio de Janeiro carnival in February features the agogô in every samba school’s percussion section. Year-round samba performances at venues such as Lapa in Rio also feature the instrument. Candomblé ceremonies in Bahia (where they are open to respectful visitors) feature the agogô in religious context. The Wikimedia Commons category collects images and audio.

Learning Resources

The agogô is one of the more approachable Brazilian percussion instruments because the basic techniques — striking and damping — can be picked up in a single session. Method books on samba percussion by Frank Colón and others cover the main carnival patterns. For Candomblé context, study should be pursued only with proper introduction within a terreiro and is not appropriate for casual learning.

Frequently Asked Questions

What family is the agogô in?
It is a struck idiophone, classed as 111.242 (sets of bells) in the Hornbostel-Sachs system.

How is the agogô tuned?
The two bells of a double agogô are inherently tuned to different pitches by their physical sizes — usually a minor third or fourth apart — and the player does not adjust them.

Where did the agogô originate?
Among the Yoruba people of present-day southwestern Nigeria and Benin. The instrument crossed the Atlantic with enslaved West Africans during the 17th and 18th centuries and became established in Brazil.

Are old African bells in museums?
Yes. The Metropolitan Museum of Art holds a 19th-century Cameroonian double bell (object 502187) and a 19th-century Congolese single bell (object 502268), both close African cousins of the modern agogô.

What is the difference between the agogô and the gankogui?
Both are West African double bells with very similar construction. The agogô is the Yoruba name (and the term that travelled to Brazil); the gankogui is the Ewe (Ghana) equivalent.

Is the agogô difficult to learn?
The basic strike-and-dampen technique can be picked up quickly. Playing tightly within a samba ensemble — and especially performing the specific rhythmic patterns of Candomblé religious ceremony — requires longer study.
