The tenth of the ten Preludes composed and published between 1927 and 1944. It was composed in 1944. In addition to these ten, two other preludes were composed, but they remain unpublished.

In 4/4 time, Moderato. It begins in D-flat major. From the outset, it sways like a pendulum, with an open and gentle sound in the high register on the fourth beat, which is beautiful. Subsequently, the atmosphere changes abruptly to B-flat minor. The phrases played in the low register are introspective and dark, descending as if sinking into the depths. This light-and-shadow-like arrangement is repeated with changing colors. Finally, amidst the dissonant sounds in the minor key, the major chord struck in the low register resonates very impressively. The standard performance time is approximately 1 minute 30 seconds.
