One of Brahms's last works, these 11 Chorale Preludes for organ feature a rich chromatic texture. The hymns chosen most often revolve around death and mourning. Numbers 9 and 10 both treat the same chorale melody, Herzlich tut mich verlangen (also used for O Haupt voll Blut und Wunden), Op. 122, Nos. 9 and 10.
