with sparser intros ("mix-ins") and outros ("mix-outs") to enable DJs to blend them together immediately. More recent forms of trance music incorporate other styles and elements of electronic music such as electro and progressive house into its production. It emphasizes harsher basslines and drum beats which decrease the importance of offbeats and focus primarily on a four on the floor stylistic house drum pattern.
