Happy hardcore, also known as happy rave or happycore, is a genre of hard dance typified by a very fast tempo , often coupled with solo vocals and sentimental lyrics. Its characteristically 4 4 beat "happy" sound distinguishes it from most other forms of hardcore, which tend to be "darker". It is typically in a mode with a major third, like Ionian or Lydian. In its original incarnation, it was often characterized by piano riffs, synthetic stabs and spacey effects. This genre of music is closely related to the typically Dutch genre of gabber. Happy hardcore evolved from breakbeat hardcore around 1991â1993, as the original house music-based rave became faster and began to include breakbeats, evolving into oldschool jungle which evolved into drum and bass. Some of the most famous artists of this genre include DJ Brisk, Scott Brown,Darren Styles, Hixxy, DJ Paul Elstak, Dune,Scooter, Stu Allan , Dougal, DJ Gammer,Team Rocket ,DJ S3RL, JTS, and Jason Suae.
