There are many characteristics that may
identify a style. There may be different step patterns, different timing of
steps, particular movement on the dance floor (eg:slot, circular), dancer
preference of turns and moves, attitude and others. The presence of one or
more of particular elements does not necessarily define a particular style.
For example, many styles can be danced "On One" or one style may be danced
"On One" or "On Two". The following are brief descriptions of major
"recognizable" styles.
Cuban-style salsa is "on one". An essential element is the "cuba step" (also known as Guapea), where the leader does a backward basic on 1-2-3 and a forward basic on 5-6-7. The follower does the same, thereby mirroring the leader's movement. Another characteristic of this style is that in many patterns the leader and follower circle around each other.
The cross body lead is an essential step in this style too and is referred to as Dile que no. The LA style is a later derivative of this, the difference again being that the dancers rotate a quarter turn around one another in the process. This move also becomes essential in the more complex derivative of Cuban Casino leading to the many moves of Rueda, or wheel dance. Here multiple couples exchange partners and carry out moves syncronised by a caller.
This style is common in Latin-American countries. The leader and follower do most of the movements while standing in place. It stems from the Cuban style. As such in many patterns the leader and follower turn around each other.
The two essential elements of this dance are the forward/backward basic as described above, and the cross-body lead. In this pattern, the leader steps forward on 1, steps to the right on 2-3 while turning 90 degrees counter-clockwise (facing to the left). The follower then steps forward on 5-6, and turns on 7-8, while the leader makes another 90 degrees counter-clockwise. After these 8 counts, the leader and follower have exchanged their positions.
LA style salsa is also known to be the most flashy style commonly danced.
The Vazquez brothers are widely credited with developing the LA style of salsa. Luis still teaches in LA.
The "NY Style" is a combination of the "On 1" and "On 2" systems. The timing of the steps are on the 1-2-3,5-6-7 as in "On 1" but the breaks (where the body changes direction) occur on the 2 and 6 as in "On 2". NY instructor Eddie Torres developed this step pattern around the late 70's and the 80's and its definition is quite clear since he is still alive and his followers are keen to keep the style intact.
This style is similar to Los-Angeles style, but it is danced "On Two". The basic step timing is 2-3-4,6-7-8 with the breaks on 2 and 6.
It is important to note that although this style is also known as dancing "En Clave", the name is not implying that the step timing should follow the rhythm of the Clave as in 2-3 or 3-2. It only means that you take the first step (and break) on the second beat of the measure.
This does indeed follow the 2-3 or 3-2 pattern of the clave, e.g. for the 2-3 clave the leader steps forward with the left on 2 and with the right on 3, then does the other 4 steps of the basic on 5-8 (syncronizing with the clave on 5 and 8). It's a traditional form and it's less known/used outside some latin countries.
This style can be danced as "On One" or "On Two". If danced as "On Two", it is always danced on count 2, and not on count 6 as in Ladies-style NY.
In the 1950s Salsa Rueda (Rueda de Casino) was developed in Havana, Cuba. Pairs of dancers form a circle (Rueda in Spanish), with dance moves called out by one person. Many of the moves involve rapidly swapping partners.
