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

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为萧邦在马悠卡创作的24首前奏曲中的乐曲，为E小调，缓板（Largo），2/2拍。此曲于萧邦的葬礼中演奏。

曲中左手部分为重复、以半音音阶下降的和弦，右手为缓慢、悲伤的旋律，最后双手同时弹出和弦作结。全曲的推进简单直接，但情感有力，使此曲较为知名。

阿尔弗雷德·科尔托将其称为“坟墓之上”（Sur une tombe），汉斯·冯·毕罗将其称为“窒息”（Suffocation），以显出此曲中的绝望情感。乔治·桑的女儿指出乔治·桑曾为每一首前奏曲加上标题，但该乐谱已遗失。其女儿有抄下每首前奏曲的标题，但未有编号。人们相信“Quelles larmes au fond du cloître humide?”（在潮湿的修道院深处流下了甚么泪水？）为对应此曲的标题。
