String Quartet no. 12 in E flat major, op. 127

Ludwig van Beethoven completed his String Quartet No. 12 in E♭ major, Op. 127, in 1825. It is the first of his late quartets. Commissioned by Nicolas Galitzin over a year earlier, the work was not ready when it was scheduled to premiere. When it was finally premiered by the Schuppanzigh Quartet, it was not well received. Only with subsequent performances by the Böhm Quartet and the Mayseder Quartet did it begin to gain public appreciation.
