Why You Can't Play Barre Chords: 10 Common Mistakes

Finger position mistakes

The first group of causes is exactly where and how the index finger sits:

• The finger lies on its flat pad instead of its bony side edge - the most common cause of several strings buzzing at once.
• The finger sits too far from the fret instead of right up against it.
• The finger sags in the middle between strings because of a natural knuckle dip - a slight roll of the finger helps.

Hand position mistakes

The second group is the thumb and overall hand position:

• The thumb presses directly opposite the index finger and clamps the whole hand, instead of sitting a bit lower.
• The elbow is pinned against the guitar's body, which doesn't let the hand find the right angle.
• The wrist is bent too far inward - that doesn't add strength, only tension.

Training mistakes

The third group isn't the technique itself, but how it's being drilled:

• Jumping straight to a full strumming pattern with the barre, instead of checking cleanliness one string at a time.
• Holding the barre pressed constantly, with no split-second rest for the hand between strums.
• Only drilling the barre on high frets, where the string is physically slacker, and never checking on low ones.
• Giving up after a few days - for most people a barre evens out over 2-4 weeks of short daily practice, not in one sitting.

How to find your specific mistake

Fret the barre and check it one string at a time as a slow arpeggio, listening for exactly which one goes dead. If it's one or two specific strings under the index finger, look for the cause in finger position; if the whole chord sounds weak and the hand tires fast, it's more likely the thumb and hand position, not the barre finger itself.
