The work is in three movements, played without breaks between each: 1. * Lento 2. * Allegretto (sometimes referred to as Poco a poco accelerando all'allegretto) – Introduzione 3. * Allegro vivace The piece was premiered on 19 March 1910 in Budapest by the Waldbauer-Kerpely Quartet, two days after Bartók played the piano with them in a concert dedicated to the music of Zoltán Kodály. It was first published in 1911 in Hungary.
