Beethoven’s final string quartets (Opp. 127, 130, 131, 132, 135) and the Grosse Fuge are considered the peak of chamber music, breaking 19th-century conventions with radical structures and deep emotional, introspective content. Composed during his total deafness, these masterpieces, including the deeply personal Op. 132 and the intense Op. 131, were initially misunderstood but later recognized as pioneering modern music.
