String Quartet No. 12

The first of Beethoven's late string quartets, the 12th Quartet in E-flat Major (Op. 127) is a massive work that showcases the changes in Beethoven's compositional technique. The first movement features a regular interruption of the theme - a technique that Beethoven used in a number of late compositions, while the third movement features a tonal progression similar to one used in the finale of the 9th Symphony.
