pizzicato Bartók
An extended string technique, also called snap pizzicato, where the string is pulled up and released so it snaps back against the fingerboard with a sharp percussive crack.
In Depth
Bartók pizzicato (notated with a circle and vertical line above the note) requires the player to pull the string vertically away from the fingerboard and release it forcefully so it rebounds against the wood with a sharp, aggressive snap. The technique produces a combined pitch-and-percussion effect far more violent than ordinary pizzicato. Béla Bartók was the first composer to use it systematically and notate it specifically, though the effect may have existed informally earlier.
The technique first appears prominently in Bartók's String Quartet No. 4 (1928), where it adds percussive fury to already aggressive passages. It has since become a standard extended technique, appearing in works by Ligeti, Penderecki, Lutosławski, and countless film and television scores. The snap pizzicato requires careful execution — pulling too hard can break the string or damage the fingerboard, while pulling too gently produces an underwhelming thud. The technique is particularly effective on the cello and double bass, where the longer, heavier strings produce a deeply satisfying crack.
Bartók pizzicato can actually damage instruments if performed too aggressively — some orchestral librarians have found broken strings and dented fingerboards after particularly enthusiastic performances of Bartók quartets.
