Budapest String Quartet has been played on NTS shows including True As Few w/ Mark, with String Quintet In G Minor, K. 516 first played on 31 May 2022.

The Budapest String Quartet was formed in 1917 by four friends, all members of opera orchestras that had ceased playing owing to World War I The members were all protégés of Jenő Hubay (violin), a Hungarian pupil of Joseph Joachim and David Popper (cello), a Bohemian. Hubay and Popper had helped to make Budapest a major centre for musical education, attracting famous students such as Josef Szigeti. Hubay and Popper had supported Sándor Végh and Feri Roth in the formation of quartets, and were themselves part of an earlier Budapest Quartet, the new quartet being named partly in honour of that. The debut recital of the new Budapest String Quartet (in Hungarian: Budapesti Vónosnégyes), took place in December 1917 in Kolozsvár, then in Hungary, now called Cluj-Napoca, in present-day Romania.

The quartet was established with quite forward-looking rules:

All disputes, musical or business, were to be resolved by a vote. In case of a tie—no change. Players were not allowed to take engagements outside the quartet. Players were paid equally—no preference was given for the leader (first violin). No wives or girlfriends were permitted at rehearsals or discussions.

No previous quartet had attempted to live entirely on the proceeds from its concerts. This was a brave decision for the time. The original members were Emil Hauser, aged 24, from Budapest; Alfred Indig, from Hungary; István Ipolyi, aged 31, from Újvidék in Hungary; and Harry Son from Rotterdam, Holland.

The Budapest probably went on longer than any quartet in musical history, maintaining a continuity of style despite changes in personnel.
