Op.130属于贝多芬晚期的四重奏作品.他那时已经全聋了, 处于深度忧郁之时. 第五乐章(共六乐章)柔和的Cavatina（短小的咏叹调）. His friend, violinist Karl Holz, wrote that Beethoven “composed the Cavatina of the quartet in B flat amid sorrow and tears; never did his music breathe so heartfelt and inspiration, and even the memory of this movement brought tears to his eyes.”
ZT: 这首短歌是对苦恼不能容忍的祈求，也是对快乐与和平的恳求，这是一首永不停歇的歌，一句连着一句，一下子就把听众抓住，在乐曲第43小节处，贝多芬标上了“沮丧”，此时小提琴停停歇歇地哭泣，心情十分沉重，最后终于得到了安慰，并在安慰声中远去。
