The String Quartet No. 2 by Béla Bartók was written between 1915 and October 1917 in Rákoskeresztúr in Hungary. It is one of six string quartets by Bartok.
The work is in three movements:
- Moderato
- Allegro molto capriccioso
- Lento
In a letter to André Gertier, Bartók described the first movement as being in sonata form, the second as "a kind of rondo" and the third as "difficult to define" but possibly a sort of ternary form. The first movement opens with a leaping motif based on the interval of a seventh - a quintessentially atonal figure. But it intertwines with tonal themes, including a strikingly tender minor-key motif that has a strongly medieval quality. Zoltán Kodály, who thought of the three movements of this quartet as "life episodes," heard "peaceful life" in the first movement, and for all its roiling emotions, the movement does indeed leave an impression of tranquility at the end.
The brooding, intense last movement (Kodály heard it as "suffering") is particularly funereal because it is as immobile as the second movement is animated. Long stretches are rhythmically static, and the parts that do move are often interrupted by silence.
The work was dedicated to the Waldbauer-Kerpely Quartet, who gave the piece its premiere on 3 March 1918 in Budapest. The work was first published in 1920 by Universal Edition.
