The String Quartet No. 4 in C major by Béla Bartók was written from July to September 1928[1] in Budapest. It is one of six string quartets by Bartok.
The work is dedicated to the Pro Arte Quartet but its first public performance was given by the Waldbauer-Kerpely Quartet in Budapest on 20 March 1929. It was first published in the same year by Universal Edition.
