5 Reasons Why Your Acoustic Guitar Won’t Stay in Tune (And How to Fix)
Some guitars just don’t seem to stay in tune. If that’s the case with yours, try the below.

Tuning Peg Problems
String Age and Quality
Dead strings don’t stay in tune. You should change your strings once per month with regular playing. Also, clean your strings after each time you play. If you play more often, or have acidic fingers, change strings more frequently, or look into coated strings.
Wood shifts with humidity, and so your guitar will subtly adjust and this can throw your tuning off. Your HVAC could be causing major humidity shifts that your guitar does not like. Check to see whether the room you store your guitar in has significant humidity shifts. You can do this by purchasing a hygrometer. You can find digital hygrometers online for around $10 to $20. You should keep the room where you guitar is stored in the 40 to 60% humidity range. If you see fluctuations outside this range, get either a humidifier, dehumidifier, or both.
Sometimes your playing style may be the problem, especially your fretting hand technique. Pulling downward (or pushing upward) on the strings when holding chords can result in a sharp tone. Also look at your initial attack for striking individual notes. If you strike too firmly against the fretboard that can result in a sharp tone. Your picking hand can cause problems, too. If you pick the strings too hard, it can create a sharp tone.
