F minor is one of the darker minor keys, its four-flat signature giving it a distinctly heavy, melancholic colour. The chord contains F, A♭, and C. Beethoven's "Appassionata" Sonata, Chopin's F minor Ballade, and Brahms' F minor Piano Sonata are all anchored here. F minor is the relative minor of A♭ major, and the two keys share their key signature.

Common mistakes
F minor's third is A♭, not A. The key signature carries the flat implicitly, but if you're reading lead sheets without a key signature you have to know it belongs there. On piano, the chord falls under the hand as white-black-white (F, then the black key just left of A, then C). On guitar, F minor is most commonly an E-shape barre at the 1st fret — and like F major, it's a famous early-stage hurdle for barre technique.
In context
F minor is the i chord in F minor, the vi chord in A♭ major, the ii chord in E♭ major, and the iii in D♭ major. Beethoven's "Appassionata" Sonata Op. 57 builds entire movements around the F minor triad; the opening of Chopin's F minor Ballade Op. 52 is one of the most famous moments in the piano repertoire. The progression Fm-A♭-E♭-B♭ (i-III-VII-IV) underlies a lot of folk and metal music.

- Beethoven's "Appassionata" Sonata Op. 57, Chopin's Ballade No. 4 Op. 52, his Fantaisie Op. 49, and Brahms' Piano Sonata No. 3 Op. 5 are all in F minor. The key carries strong associations with passion, struggle, and melancholy.
