Bachata Dance

Bachata, a form of music and dance that originated in the countryside and rural marginal neighborhoods of Dominican Republic. Its subjects are often romantic; especially prevalent are tales of heartbreak and sadness. In fact, the original term used to name the genre was "amargue" ("bitterness," or "bitter music"), until the rather ambiguous (and mood-neutral) term bachata became popular.
Bachata was created and primarily used by servants, who used to play it when they got off of work. They made the music out of ordinary objects like those commonly found in a backyard (Trashcans, Fences,etc). In some rural areas of the Dominican Republic, bachata means trash, but most citizens agree that it means a party. Others say that bachata is derived from the Italian Ballata, which was a popular form of music in Italy centuries ago.
The music itself is played in 4/4. The most recognizable aspect of bachata instrumentation is the use of an amplified guitar (either electric or acoustic) whose sound has been doctored with a flanger, reverb, echo, or a combination of the three. The use of arpeggiated chords as the basis for the melody is almost standard. An additional guitar, called the 'segunda' or rhythm guitar is usually mixed at a lower volume, and provides syncopation. An electric bass guitar and güira help anchor the rhythm - with the güira sounding a bit like a high-hat (in pre 1990s bachata, maracas were played instead of güira). The use of the bongo drum further solidifies the basic beat, and provides and percussive accents in transition points - for instance right before a chorus.
Derived from the Latin American tradition of guitar music, and originally named for the crude bars and clubs where guitarists and singers would perform, bachata emerged in the 1960s. According to a documentary, the Beatles cover of Till There Was You (first performed in 1963) helped inspire the genre. Even though some set the origins of Bachata to the early 60s, Bachata songs were played in the brothels of the Dominican Republic in the early 50s. In 2002 a commemorative album was released celebrating the 50th anniversary of the Bachata music. While popular radio filled the air waves with merengue and salsa, bachata musicians were forced to develop their own system of producing and distributing their music. As with most styles of Latin American music, the bachata played today uses electric guitar and has phrasing which is more rhythmic and groove-like than in earlier styles. The evolution to electric has perhaps helped make bachata more accessible.
