The string quartets of Béla Bartók are unquestionably among the peaks of 20th-century chamber music. In these six masterworks, the Hungarian composer conveyed a classical sense of harmony and balance using entirely new and non-classical means.
The five-movement layout of Quartet No. 4 consists of two thematically related fast movements in the first and fifth place, two scherzo-type pieces (also related) as movements 2 and 4, and an emotionally intense central slow movement. It is an example of Bartók’s predilection for symmetrical constructions. Those constructions are realized with extraordinary timbral and textural imagination, as frequent double and triple stops, tremolos, glissandos and other technical devices add their dramatic contributions to musical form.
The first and last movements, which share most of their thematic material, differ in that the finale turns the main theme, originally a lyrical melody, into a folk dance. The second and fourth movements likewise share their melodic outline while strongly differing in character. In the second movement, the melody moves in small, chromatic steps and the performers play with their mutes on, whereas in the fourth, the melody is stretched out, moving in larger, diatonic steps; instead of using mutes, the performers play pizzicato (plucking the strings) throughout.
The central slow movement begins with an expressive cello solo, which is a reflection (though not a direct imitation) of the hora lungă. This type of Romanian folk music was particularly important to Bartók because he saw it as an ancient musical form, close to improvisation.
