In electronic music, "acid breaks" is a fusion between breakbeat, acid house and other forms of dance music. Its drum line usually mimics most breakbeat music, lacking the distinctive kick drum of other forms of dance music. One of the earliest synthesizers to be employed in acid music was the Roland TB-303, which makes use of a resonant low-pass filter to emphasize the harmonics of the sound.
There has been a resurgence of this sound, using Amen breaks, Reese bass, and TB-303 acid lines to create energetic, and sometimes frenetic acid breaks songs.
