Man, I would love to be able to say something sensible here, but I feel I am totally unqualified. Who is offering him/herself as a guest columnist?
Salsa music is not based on a backbeat, such as a lot of dance music, but rather on a rhythmic concept called the clave. Just to confuse you, there is a rhythm instrument called claves, which consists of two wooden sticks that you hit together. Sometimes claves are used to play the clave, but keep the distinction in mind.
Clave is a 2-bar, 8-beat rhythm pattern that is repeated
throughout a piece of salsa music. One bar is called the two-side,
the other the three-side. In the two-side beats 2 and 3 are used,
in the three-side beats 1, (2)&, and 4. Depending on which comes first,
a piece of music is said to be based on a 2/3 clave or a 3/2 clave.
There is actually a relation between the two halves of the clave, and binary
rhythms in other music: one side of the clave is the weak side and the other
the strong side. Thus, there is the same tension/release structure we have
seen in other forms of dance music.
The bass in salsa music often plays a rhythm, called
tumbao, that is based on the three side of the clave. That is, the
bass does not play a two-bar pattern based on the two-side and the three-side,
but rather it keeps repeating the three-side. Example; Usted
by Alfredo de la Fe. Play. The rhythm is of course not always played so
clearly; you can hear that after a few repetitions the bass player in this
example starts to embellish on the basic rhythm, but the essence remains
the three-side of the clave.
Dancers used to rhythmically simpler music are often thrown by this rhythm, since there is no heavy accent on beat 1. In other words, you are supposed to take your first step, starting the dance even, on a beat that is not clearly marked. This is true, and you will have to learn to deal with it. Still, knowing how this bass rhythm works can often be the key to finding beat one.
