Of the Op. 18 string quartets, this one is the most grounded in 18th-century musical tradition. According to Steinberg, "In German-speaking countries, the graceful curve of the first violin's opening phrase has earned the work the nickname of Komplimentier-Quartett, which might be translated as 'quartet of bows and curtseys'."

The nickname may have originated from one of Haydn's last string quartets written about the same time (Op. 77, No. 1; 1799), which was also known as the Komplimentier-Quartett. Haydn was Beethoven's teacher at the time, and there are similarities in style between the two quartets. They are also both in the key of G major.

After he finished the quartet, Beethoven was not satisfied with the second movement and wrote a replacement. Sketches of the original slow movement survive and a complete version has been reconstructed by musicologist Barry Cooper. It was performed publicly, possibly for the first time, by the Danel Quartet in the Cosmo Rodewald Concert Hall at the Martin Harris Centre, University of Manchester, on 30 September 2011.
