Late string quartets (Beethoven)

Ludwig van Beethoven's late string quartets are:

• Opus 127: String Quartet No. 12 in E♭ major (1825)
• Opus 130: String Quartet No. 13 in B♭ major (1825)
• Opus 131: String Quartet No. 14 in C♯ minor (1826)
• Opus 132: String Quartet No. 15 in A minor (1825)
• Opus 133: Große Fuge in B♭ major (1825; originally the finale to Op. 130; it also exists in a piano four-hands transcription, Op. 134)
• Opus 135: String Quartet No. 16 in F major (1826)

These six works are Beethoven's last major completed compositions. Extremely complex and largely misunderstood by musicians and audiences of Beethoven's day, the late quartets are now widely considered to be among the greatest musical compositions of all time, and have inspired many later composers.
