Speedcore

Speedcore is a form of hardcore that is characterized by a high tempo and aggressive
themes. The genre was created in the early to mid 1990s and the name originates from the
genre hardcore as well as the high speed tempo used. This music rarely drops below 300
beats per minute (bpm). Earlier speedcore tracks often averaged at about 250 bpm, which
could be defined as terror(core), whereas some tracks sometimes exceed 1000 bpm where it
then becomes known as extratone, one of the world's fastest music genres.
