The conga is a tall, narrow, single-headed Cuban drum with African antecedents. It is thought to be derived from the Makuta drums or similar drums associated with Afro-Cubans of Central African descent. 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 are 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, merengue music, Reggaeton, 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 the bottom 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.
While they originated in Cuba, their incorporation into the popular and folk music of other countries has resulted in diversification of terminology for the instruments and the players. Ben F. Jacoby's 'Introduction to the Conga Drum' holds that the drums are called congas in English, but tumbadoras in Spanish. The drums, in order of size from largest to smallest, are The tumba, conga, quinto, the rare requinto, and the side-strap mounted ricardo. 'The Conga Page' agrees with the congas vs. tumbadoras terminology. 'Music of Puerto Rico' refers to the drums only as congas, but gives the names as tumba for the largest, niño for the smallest, and does not provide names for the two middle drums. Alex Pertout's 'The Conga Drum: an Introduction' points out that the names for the individual drums vary even in Cuba, and gives the names of three drums: tumbadora (largest), conga or segundo (middle), and quinto (smallest).
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 , 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.
There are five basic strokes:
The moose call or glissando is done by rubbing the third finger, supported by the thumb, across the head of the drum. The finger is sometimes moistened with saliva or sweat, and sometimes a little coat of beeswax is put on the surface of the conga head to help make the sound . The moose call is also done on the bongos.
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.
Occasionally sticks are used on congas: some sticks, such as the Regal Tip's  conga sticks are made to imitate the sound of a hand hitting a conga; even timpani mallets, timbale sticks, etc. have been used on congas, despite the fact that the conga is usually called a hand drum.
There are various rhythms for the conga, the most well-known being the marcha.This rhythm is commonly played on 1 to 3 congas, but has no true limit for the amount used. The marcha is the most common rhythm in Salsa/Son.Some songs that include the marcha or slight variations (Guajira)(chacha) of the rhythm are:
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.
The merengue rhythm, used in orchestral merengue, goes 1 2-1-2. It can also be heard as 1-2-1-2 1-2-1-2-1-2. Essentially, it is the rhythm of the tambora applied to conga. This can be heard on Elvis Crespo's Suavemente and Grupo Mania's Me Miras y Te Miro. Originally, this rhythm was derived from the trap drumming of African slaves from various animist religions. In merengue tipico the rhythm is usually more complex and less standardized; it can range from simply hitting the conga on a fourth beat to playing full patterns that mark the time.
The cumbia rhythm, simple and slowly played, goes 1-2-2-1, also heard as 1-2-1-2. It can be heard in Fito Olivares's Mosaico Fiestero and La Cumbia Sampuesana y La Cumbia Cienaguera by Ancieto Molino y Los Sabaneros.it was an important thing to know
There are many other kinds of rhythms for the conga. It is constantly applied in new genres of music, therefore taking up the rhythms of that specific style, such as punta, reggaeton, Brazilian forms such as samba and bossa nova, and even reggae, funk, go-go, and country music.
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.
