The conga is tall, narrow, single-headed Cuban drum of African origin, probably derived from the Congolese Makuta drums or Sikulu drums commonly played in Mbanza Ngungu, Congo. A person who plays conga is called a "conguero".Although ultimately derived from African drums made from hollowed logs, the Cuban conga is staved, like a barrel. These drums were probably made from salvaged barrels originally. They were used both in Afro-Caribbean religious music and as the principal instrument in Rumba. Congas are now very common in Latin music, including salsa music, as well as many other forms of American popular music.
Most modern congas have a staved wooden or fiberglass shell, and a screw-tensioned drumhead. They are usually played in sets of two to four with the fingers and palms of the hand. Typical congas stand approximately 75 cm from thebottom of the shell to the head. The drums may be played while seated. Alternatively, the drums may be mounted on a rack or stand to permit the player to play while standing.
The Glossary Of Latin Music Terms agrees with tumba / conga / quinto, but defines the extra super quinto drum, smaller than the quinto. The term tres golpes may also be used for the conga. Artdrum.com's History of Conga Drums also agrees with the terms tumba / conga / quinto, but allows the synonyms segundo (for conga) and tumbadora or salidor (for tumba). Poncho Sanchez, in his Conga Cookbook, added a drum below the tumba, which he called the supertumba.
Conga players are called congueros, while rumberos refers to those who dance following the path of the players. The term conga was popularized in the 1950s, when Latin music swept the United States. Cuban son and New York jazz fused together to create what was then termed mambo, but later became known as salsa. In that same period, the popularity of the Conga Line helped to spread this new term. Desi Arnaz also played a role in the popularization of conga drums. However, the drum he played (which everyone called a conga drum at the time) was similar to the type of drum known as boku used in his hometown, Santiago de Cuba. The word conga came from the rhythm la conga used during carnaval (carnival) in Cuba. The drums used in carnaval could have been referred to as tambores de conga since they played the rhythm la conga, and thus translated into English as conga drums.
To bend the pitch of the conga, a "conguero" sometimes uses his elbow to shift around on and apply pressure to different parts of the head; this causes the note to change. This is not a traditional stroke, but it is common in modern salsa and rumba.
Countless other songs use this rhythm.
There is also the bolero rhythm, which goes 1-2-3 1-2 1-2-3. Being very similar to the marcha, it involves a minimum of two congas and can be heard on:
More complex rhythms can be heard in the music of Santeria and Abakua rituals, many of which also apply to the bata drums, such as Guarapachangueo and Chacha-lokafun. In Cuba, variants of Guaguanco, Bembe, and Abakua change from province to province, so there is no true stating to what is or isn't correct.
Conga drums are tunable to different notes. The original drums were tuned by adjusting knots and tension ropes on the drumhead, or, where the drum-heads were tacked or nailed to the top of the shell, by careful heating of the head. Modern congas use a screw-and-lug, tension head system which makes them easier to tune (or detune). As was discussed above, terminology for the drums varies. Here, the naming system used is a composite of those mentioned before with those currently in use by major conga manufacturers. The drums are discussed in order from largest to smallest; the sizes of the drumheads given vary considerably by manufacturer, model, and style.
Congas, being percussive instruments, do not have to be tuned to any particular note in purely percussive settings. However, when playing with harmonic instruments, they may be tuned to specific notes. Congas are often tuned using the open tone (see above). In general, the particular note will depend on the make, model, and size of the conga drum. The drum should be tuned so that the bass tone resonates, the open tone rings, and the slap pierces through the musical mix. If the tuning is too loose, the bass and slap tones will sound "flabby"; too tight, and the drums will sound unnatural and "pinched." With a single drum, it is easy to tighten the drum until it makes a pleasing sound and then tighten a little more to reach a uniform desired pitch. It is very important to ensure that tuning is uniform around the drumhead, which can be checked by placing one finger pad in the center of the head and tapping the head near the edge above each lug location to detect any change, adjusting as necessary. Uniform tightness will help "let the drum speak."
Another important consideration is that head tension can greatly impact the ease or unease of the player, and generally a looser drumhead can lead to hand injury more than a tighter one, because a looser drumhead has less rebound and more muffling effect (hence potentially bruising joints and bones under spirited playing). Also, producing a crisp slap tone is nearly impossible on a loose head. During tuning it is suggested to "let the drum speak" and to conform tuning reasonably closely to the natural resonance (pitch) that the cavity of the drum interior presents. This resonance can be heard by singing or playing loud notes near the drum opening (this is true of tuning any drum) and noticing which pitch decays slowest (that will either be the fundamental [resonant] frequency or one of its simple overtones).
When two or more drums are used, there is a potential for more variation of which notes are chosen, however tuning between or during compositions is rare in live performance. With only two drums, it is common to find them tuned a perfect fourth apart (the same interval used in "Here Comes the Bride") as is the tradition in western classical music for the timpani. Having three drums (typically the tumba, conga, and quinto) invites experimentation and individual customization. Some congueros like using the intervals of a major chord (e.g. F, A, C). Some players use the second inversion of a major chord (eg. G, C, E); and some prefer a major second between the quinto and conga, with a perfect 4th descending to the tumba. Raul Rekow of Santana often plays five conga drums and tunes them to the opening phrase of a Latin tune.
