It is so frustrating when one specific chord has this annoying buzz, right? You place your fingers where you think they need to go, strum very carefully, but that one buzzing sound still manages to interrupt your practice session. Most beginners experience this phenomenon often with the open C shape, D, or Am shape. It can seem unfair because some other chords may sound fine. But fretless guitar sounds can tell you something valuable. If a note is buzzing or dead, you have a great opportunity to figure out what went wrong with your hand position or your technique, which makes your practice sessions way more effective.
First of all, instead of strumming the whole chord multiple times, listen to each individual string. Put your fingers down in the chord shape, then carefully pluck each string from low to high. The problem string will pop out as a dull thud. Find the finger that is fretting the dead string, and look at its placement. Are you too far away from the fret? Are you falling sideways, hitting an adjacent string? Are you flattening your fingertip so that you can’t get enough downward pressure on that string? Small changes, rather than increased force, can make a difference here. Try moving that finger just a little closer to the fret, and then rounding that finger more, and play again.
If that string continues to buzz, move on to your other hand, the left hand that is holding your fretting arm. You should notice that your thumb often gets too loose, so your wrist is no longer straight, and all of your other finger positions get messed up.
Many players just keep strumming that chord again and again, trying to press harder and harder every time to get it to work. Although this is intuitive, it is rarely correct. You don’t need excessive pressure, and pressing down on the strings with excessive force will make it much more difficult to get all the strings to ring because your hand becomes tense in the palm, the wrist, and even the forearm. Instead, you should play through the strings, with just enough pressure to make each string ring clearly. Instead of trying to put the shape of your hand on all at once, you should put each finger in place one at a time. Place your first finger down, strum it, then place your second finger down, and so on until the rest of your fingers have settled into place. In this way, you can identify whether your problem is specific to one finger, or whether your whole hand just isn’t quite in the right position for the overall chord shape.
A very short (15 minute) period of time is more effective than one that is much longer. Begin with a few minutes where your hands are putting this chord shape on very slowly, playing the string each note individually. Take a break, move your hands back into a neutral position, and re-apply that chord shape. Wait a moment so the fingers can settle before you strum. Pay attention to the shape of your fingers and whether the fretting position is in the right place. While in the middle of a practice session, switch from that problematic chord to a chord that you know works, and then back again. Try to do this while your hand is still moving rather than holding it still. Save a few minutes for the end of practice to do a musical exercise that incorporates that specific chord. For example, you might pick and strum each chord once. That way, you are thinking musically and not just mechanically in your practice sessions.
Remember that if the string continues to buzz from day to day, that does not mean you have done anything wrong. You are doing exactly what you need to do in the beginning with the guitar to help yourself find that chord. It simply takes time and repetition for your hand to learn how to find the position, the pressure, and the shape required to sound correctly. Listen for incremental improvement, which means that you just need a few extra strings to buzz a bit less, or one additional note to ring a bit louder, or one finger position that has to move more to find the note. In time, you will become more comfortable with that chord. You are not trying to find the ideal guitar-playing posture tomorrow morning; instead, you are learning to identify problems, address them, and give your fretting fingers more opportunities to land in the right place so that they sound good when they do.
