Prelude Op. 28 No. 4 in E Minor 前奏曲作品28之4 E 小調

The Prelude Op. 28, No. 4 by Frédéric Chopin is one of the 24 Chopin preludes in Mallorca. By Chopin's request, this piece was played at his own funeral, along with Mozart's Requiem.

The piece is only a page long and uses a descending melody line. The melody starts with the dominant B and works its way to the tonic E, but halfway through the piece the descending line is interrupted and the melody starts over again. Only in the last bars does the melody dissolve in the tonic and go through a chord progression to the soothing and satisfying E minor chord.
Hans von Bülow called the prelude "suffocation", due to its sense of despair. In fact, Chopin's last dynamic marking in the piece is smorzando, which means "dying away". But the prelude may have once been given a title. According to George Sand's daughter Solange, who stayed with the composer at the monastery in Mallorca when the preludes were written, "My mother gave a title to each of Chopin’s wonderful Preludes; these titles have been preserved on a score he gave to us." That titled score is lost. But Solange did record the names of the preludes, apparently without assigning the names to the prelude numbers. 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.

前奏曲Op. 28, No. 4為蕭邦在馬悠卡創作的24首前奏曲中的樂曲，為E小調，緩板（Largo），2/2拍。此曲於蕭邦的葬禮中演奏。

曲中左手部分為重複、以半音音階下降的和弦，右手為緩慢、悲傷的旋律，最後雙手同時彈出和弦作結。全曲的推進簡單直接，但情感有力，使此曲較為知名。

阿爾弗雷德·科爾托將其稱為「墳墓之上」（Sur une tombe），漢斯·馮·畢羅將其稱為「窒息」（Suffocation），以顯出此曲中的絕望情感。喬治·桑的女兒指出喬治·桑曾為每一首前奏曲加上標題，但該樂譜已遺失。其女兒有抄下每首前奏曲的標題，但未有編號。人們相信「Quelles larmes au fond du cloître humide?」（在潮濕的修道院深處流下了甚麼淚水？）為對應此曲的標題。
