Many guitarists' experience really changed once they learned how to play barre chords. Being able to play barre chords, you can open a whole new world of song selections and possibilities. If you ask what is the best barre chord to start with... the answer would be the same as for many others - it's F major chord.
This chord has been left until last, because, honestly, it's a toughie. As the saying goes... "it's not called an F-chord for nothing!"
Many new guitarists have a problem with the F major chord because it involves a new concept - using your first finger to press down frets on two strings.
Start by placing your first finger on the first frets of both the first and second strings. Now, slightly roll the finger back (towards the headstock of the guitar). Many people find this technique makes playing the Fmajor chord slightly easier. Next, place your second finger on the second fret of the third string. Lastly, place your third finger on the third fret of the fourth string. Strum only the bottom four strings, and you're playing an F major chord.
Chances are, at first, very few, if any of the notes will ring when trying to strum this chord. Check to make sure your second and third fingers are curled, and not flattened against the other strings of the guitar. Although this chord seems nearly impossible at first, within weeks, you'll have it sounding as good as the rest of the chords you play.
