How to use our acoustic guitar tuner
Tuning your acoustic guitar has never been easier. To get started, simply click on the virtual guitar picks above. Each one plays the sound of a perfectly tuned string. Start with the low E string and work your way across the neck to the high E string. As each note plays, listen carefully and adjust the tuning pegs on your own guitar to match the pitch by ear. This is known as “relative tuning” and is a reliable method for players of all skill levels.
This tuner is based on standard tuning (E A D G B E)—the most commonly used tuning setup for acoustic guitars. Whether you’re a beginner learning chords or a more experienced player preparing to record, matching your strings to these reference tones ensures your guitar sounds clear, consistent, and harmonically balanced.
You can use this tool at home, on stage, or even while traveling. It’s accessible across all devices, so whether you’re on your laptop or your phone, you’ll always have a tuning reference on hand.
How often should you tune your acoustic guitar?
You should tune your acoustic guitar every time you play—yes, even if you tuned it yesterday.
Acoustic guitars are made of wood, which reacts to its environment. Factors like humidity, temperature, and even the amount of playing can cause your guitar to fall out of tune over time. Here are the most common reasons your tuning might drift:
- Temperature changes: Moving between a warm room and a cold one causes the wood and strings to expand and contract slightly.
- Humidity: Dry or moist air can warp the guitar neck or body, affecting string tension.
- New strings: Fresh strings take time to “stretch out” and settle into stable tuning.
- Frequent playing: Strumming and finger pressure naturally pull on the strings, slowly loosening them.
- Transportation: Carrying your guitar in a gig bag or case—even carefully—can cause minor tuning shifts.
- Storage: Guitars left leaning against a wall or stored poorly may develop tension changes in the neck over time.
Even high-end or professionally set-up guitars aren’t immune. If your guitar ever sounds “off,” don’t worry—it’s completely normal. Regular tuning is simply part of owning and playing an acoustic instrument.
By making tuning part of your routine, you’ll not only improve your ear but also ensure your guitar always sounds its best.
