This is a very popular barre chord version of the F major chord.

Imagine taking the open E chord and moving everything up a half step (in other words, move everything up 1 fret). Now you have an F chord!

To play this barre chord you’ll create a “barre” using your first finger. Imagine your 1st finger acting as the nut of the guitar. You’ll use your remaining fingers to flesh out the rest of the chord.
