Dance-pop is dance-oriented pop music genre that originated in the early 1980s. It is generally up-tempo music intended for nightclubs with the intention of being danceable but also suitable for contemporary hit radio. Developing from post-disco, new wave, synthpop, and house, it is generally characterised by strong beats with easy, uncomplicated song structures which are generally more similar to pop music than the more free-form dance genre, with an emphasis on melody as well as catchy tunes. The genre, on the whole, tends to be producer-driven, despite some notable exceptions.
Dance-pop borrowed influences from other genres, which varied by producer, artist and period. Such include contemporary R&B, house, electro, trance, techno, electropop, new jack swing, funk, synthpop, and some forms of disco. Being mostly a mainstream pop-influenced genre, dance-pop's sound was often influenced by the period.
Dance-pop is a popular style and there are several artists and groups who perform in the genre. Notable ones include Madonna, Britney Spears, Kylie Minogue, Gloria Estefan, Christina Aguilera, Jennifer Lopez, Spice Girls, Paula Abdul, Backstreet Boys, Michael Jackson, NSYNC, Destiny's Child, Janet Jackson, Rihanna, Katy Perry, Lady Gaga, Ariana Grande and Selena Gomez.
