2 in A minor by Béla Bartók was written between 1915 and October 1917 in Rákoskeresztúr in Hungary.
The work is in three movements: 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.
Long stretches are rhythmically static, and the parts that do move are often interrupted by silence.
[1] The work was dedicated to the Waldbauer-Kerpely String Quartet [hu], who gave the piece its premiere on 3 March 1918 in Budapest.
