Bartók - String Quartet No. 4, Sz. 91

The quartet is built in a five-movement arch form, where the outer movements mirror each other and the central movement serves as the keystone. The pattern is: fast, scherzo, slow, scherzo, fast—a structural design Bartók also used in other works.

'Bartók pizzicato' is a technique where the string is plucked so forcefully that it snaps against the fingerboard, producing a sharp percussive sound. It appears prominently in the fourth movement of String Quartet No. 4, composed in 1928.

Béla Bartók completed String Quartet No. 4 in 1928. It is one of six string quartets he composed across his career, collectively considered among the most significant contributions to the genre in the 20th century.

The third movement, at the center of the arch, is a slow, hushed nocturne played entirely with mutes and evoking the sounds of nature at night. This 'night music' style became a signature of Bartók's writing, characterized by eerie silences punctuated by bird-like calls.
