According to Dictionary.com, House Music is:"an up-tempo style of disco music characterized by deep bass rhythms, with elements of rap music". This definition does not show the reality of this type of music. House Music is a contemporary genre, which depends on the DJ, the mixer, who makes mixes, which are called also music tracks with just a little of singing; it can be Rap, pop, hip-hop, and not just Rap as the site's definition says.
The tunes are made of defferent sounds, starting from instruments to electro sounds. These sounds are combined by a board that is called The Mixing Board. The reaons that singing has just a little share is that house songs publicize the music, the DJs, and not the artists. The most famous Djs in the world now are David Guetta, Avicii, Tièsto, Afrojack, Swedish House Mafia and Eduard Maya. Since this music was brought to the world, discos and dance clubs are full because of the efforts of the great DJs.
