Why do my barre chords sound bad?
The biggest problem with barre chords is that a student is usually told (or not corrected) when they think they need to press harder to make the barre chord sound clear and free from buzzing. Usually, the guitarist uses bad technique and far too much force to try to play them.
Are barre chords supposed to hurt?
They really shouldn't have to hurt that much. Maybe your technique is off or your guitar is set up badly (the higher the action, the harder bar chords become). It definitely does, I've been playing for about 10 months and my hand only starts getting tired after playing my acoustic for a while (high action).
What is the hardest barre chord?
The six-string F chord is one of the hardest standard chord shape to play on the guitar. When many people try to play the F chord on guitar (and often succeed) it's with far too much struggle and effort than is actually necessary. Even extremely influential guitarists can have a hard time with barre chords.
