Fm7
F Minor 7th · 4 fingerings
The minor seventh adds a flat seventh to a minor triad, softening it into something warm and relaxed rather than sad. Fm7 is everywhere: it's the ii chord in jazz, the backbone of soul and R&B rhythm playing, and a staple of funk. One of the most useful chords you can learn after the basic triads.
