Your guitar can sound out of tune if it is really out of tune. Ha! The most obvious reason! When ALL the strings of your guitar are not tuned properly, your playing will surely sound a little ‘offish’. If 5 out of 6 of your guitar strings are properly tuned, that’s a pass mark, it should sound fine, right? Wrong! For your chords, solos, strumming and everything you play on the guitar to sound as perfectly as you want them to sound, you must tune ALL of your strings properly, leaving out no one. Tuning a guitar has been made easy, you can either use a high-quality electric tuner or simply use a tuner app on your mobile phone. Asides this obvious reason, there are lots other reasons your guitar may sound out of tune.

Your guitar can sound out of tune if your strings are worn

Old or worn-out strings lose their ability to hold tension, string tension is primarily what makes a guitar string stay in tune and when that tension is gone as a result of the wearing out of the string, the strings start to sound sharper. All you need to do is get a fresh pair of strings and replace the old ones (it is advisable to replace all your strings at the same time, not one or two or randomly at different intervals. Even if only one string appears to be old or rusty, replace them all). If you’re unsure of how often you should replace or change your guitar strings, find out all about that here. Clean your strings often to preserve the life span and slow it down from wearing out fast, avoid moisture or grease from coming in contact with your strings and always wipe your hands clean and dry before you play.

Your guitar can go out of tune if it just had a string change

This is because new strings stretch, so after fixing the strings on the guitar, they will stretch and become loose, making you sound out of tune, the solution to this is to manually stretch the strings with your hands after you’re done restringing your guitar, do this before you tune the guitar, that way your strings will stay in tune because there’s no opportunity for them to stretch themselves again, they have already been stretched manually by you.

Here’s a guideline on how to stretch your strings:

  • Face the fretboard, and tuck your index and middle finger below any given string at around fret 20.
  • Now place your thumb onto the string, holding it against the fretboard.
  • With your thumb holding the string against the fretboard, pull upwards with your index and middle finger, so you are stretching the string.
  • Repeat this higher up on the same string in 2 more positions (around fret 13 and fret 6).
  • This will cause your string to go out of tune, since you are stretching it. Now tune the string to pitch, and repeat the process on the SAME string, until you don’t really need to retune it anymore. Make sure that when you tug on the string, you do it gently, don’t want to break it.
