Check the setup before the shape
Check your tuning with a suitable tuner. Then make sure you are playing the strings the chord includes. An extra low string can change the sound even when your fretting fingers are in the intended positions.
Use a familiar chord for the check. E minor is convenient because its open shape includes all six strings.
A muted note: look for contact
Play the chord’s strings separately. When you find a dull or missing note, look at whether a neighbouring finger is touching that string. An open string needs room to vibrate; the underside of a finger can stop it sounding.
Try a small change in finger angle. Keep the change small enough that you can hear whether it helped. Then play the same string again before strumming the whole chord.
A buzzy fretted note: check the position
Place the fingertip in the intended fret space, close behind the metal fret. A position far back in the space can make a clear note harder to produce. Pressing directly on top of the metal is a different problem.
Use enough pressure to hold the note clearly, then see whether you can avoid unnecessary tension. Check one adjustment at a time: location first, then pressure, then the full shape.
If the shape looks right but the problem persists
Play the same string open and then at a few different frets. If the buzzing appears across different shapes, the instrument’s setup, strings or condition may be involved. A guitar technician or experienced teacher can help distinguish a setup issue from a fretting issue.
Our static guide cannot inspect your guitar or hear your playing. It is a checklist for your own observation, not an assessment of the instrument.
Finish with a repeatable check
- Form the chord slowly.
- Play each included string separately.
- Locate one unclear note.
- Make one small adjustment and check that note again.
- Strum the chord, lift away and return to the shape.
Keep this check short. Return to playing something musical once the particular problem is easier to recognise.
