Dubstep

Dubstep is a brand new genre of music that originated in London, England. It is a type of electronic dance music which features copious amounts of low bass lines, persistent drum patterns, clipped samples, and infrequent vocals. This new-wave of music was introduced in 1998, and was more dark and experimental than today's tracks. The main instruments used are turntables, samplers, drum machines (actual drum sets are rarely used), synthesizers, keyboards, and often times a computer is used to create the same sound at a cheaper production standard.

This brand new art form, taking resemblance in musical tones, does not frequently follow the "four-on-the-floor" rhythmic pattern, systematic of other types of electronic dance music, and disco. "Four-on-the-floor"  is a steady beat which the bass drum hits on every beat in a 4/4 time signature. This term arrived from the bass pedal being on the floor and when play with a drummer's foot, the pedal is brought to the floor (in this case, four times). This technique is also sometimes seen in some Reggae music and a different style is instigated in Jazz.
