The Prelude Op. 28, No. 4 by Frédéric Chopin is one of the 24 Chopin preludes. By Chopin’s request, this piece was played at his own funeral, along with Mozart’s Requiem.
It is believed that the title “Quelles larmes au fond du cloître humide?” (“What tears [are shed] from the depths of the damp monastery?”) corresponds to Prelude No. 4.
