Smutna opowieść (Preludia do wieczności) [Polish for A Sorrowful Tale (Preludes to Eternity); less frequently translated as A Sad Story], in F-sharp minor, Op. 13 is the fifth of Mieczysław Karłowicz's six symphonic poems and the last finished work of him (though begun before this, the , Op. 14 remained unfinished at the time of his death). Harmonically, it is the most innovative of all his compositions, while stylistically it is near to the aesthetic of expressionism. It is also the shortest of his symphonic poems at just 221 bars lasting about 11 minutes.
