Hardstyle is an electronic dance music genre mixing influences from hardtechno, hard trance, hardcore and rave music. The average tempo is between 140 and 160 bpm (beats per minute).
The hardstyle sound typically consists of a "heavy" sounding kick, intense reverse basslines, and "adrenaline-rushing" melodies. It bears some similarities to hard trance. Many hardcore artists produce hardstyle tracks as well. One of the most recognizable characteristics of hardstyle is that the 4/4 rhythm is made up of 4 triplets where the main beat is heard on the first of the three notes, and a secondary beat, chord, or sound effect is heard on the third of the three notes; just before the next beat. This creates a somewhat "pulsating" rhythm that characterizes the genre.
