So i'm pretty new to guitar. I have a problem with my guitar is out of tune when im fretting a string. I can tune every string exactly, but when i'm fretting it, it is out of tune. When i play the string normaly again, it is still in perfect tune. It is not all my string that is like that, but on the string with this problem, it is on every fret. Im no sure if i am an idiot or if there is something i can do about it.
This is a common challenge with beginning guitarists. From most likely to less likely:
- you put your finger halfway between frets, instead of close to the blocking fret, requiring you to push harder
- your finger unintentionally pulls the string sideways
- your finger just pushes the string more than necessary
- your guitar has a high action, because of poor build tolerances
- your guitar needs to be adjusted (action and/or intonation)
- your open string is actually also out of tune (within equal temperament tuning), but it is less noticeable in that particular chord or interval.
I guess what I am saying is: first examine your technique, before questioning the instrument. (Not all strings are equally sensitive to this stretching, which could explain why you only notice it on some).
Two basic reasons come to mind.
First to check is the guitar's intonation. That's checking whether the 12th fret is where it should be. Sounds daft, but the position of the bridge, or saddle, is exactly te same distance from the 12th fret as the 12th fret is from the nut. Sounds complex, as the 12th fret cannot be moved!
However, the bridge or saddle can be, and by comparing the 12th fret harmonic pitch to the 12th fret fretted note - which ought to be the same - the string can be what we call intonated.
Second - the guitar's action - the height the string is from the fretboard - may be way too high. This will show itself in the fretted note always being too sharp.That's due to the string needing to be pressed too hard, stretching it thus making it sound too high in pitch.Answer would bee to lower the bridge and/or change the curvature of the neck, by adjusting the trussrod.
A lot of the solutions need experience, so a trip to a luthier is advised unless you're brave, foolhardy or experienced.
Another simple, common problem most of us have is just that we press down too hard. Maye the strings are too heavy, causing this to be necessary, but often, we press them too hard anyway.Or bend them sideways while doing just that.
