Nightcore

nightcore
The type of music that started as a subgenre of trance and is still considered so by many people. Trance fans usually call is happy hardcore. However nightcore fans prefer to not be associated with trance and don't like the idea of naming a "nightcore" as anything else.

Nightcore is characterized by a sped-up melody (sometimes), fast rhythmic beat (usually), and ALWAYS higher than normal pitch. Almost all nightcore music are original songs nightcored (remixed into nightcore) by nightcore fans.

Very popular is a belief that nightcore is a nickname of a person who remixes the songs. In reality anyone who knows how to use a computer can nightcore a song and upload it on Youtube.
