Tech Trance is a sub-genre within electronic dance music that draws upon the techno and trance genres as the name suggests.

Tech trance was pioneered by among others Oliver Lieb in the mid 1990's. Other early examples of tech trance producers are Humate, Chris Cowie and Marmion. Tech trance evolved in a new direction during the early 2000's. By 2006, the most widespread variant of trance was the still growing and evolving genre of tech trance, pioneered by the likes of producers such as Tiesto, Marcel Woods, Marco V. The new style appealed to Trance DJs such as Ferry Corsten and Armin van Buuren, who then started incorporating tech trance into their sets. Since then tech trance has continued to evolve as a subgenre of trance, with many established trance producers and newcomers incorporating the style in their sets or focussing solely on it.

Tech trance incorporates traditional elements of techno, with its repetitive nature and strong 4/4 beat, while deriving the melodic elements from Trance. Tech trance compositions tend to have a tempo of around 135-150 beats per minute, which is still significantly slower than hard house or hard trance.
