How to tune a guitar

Ensuring your guitar is properly tuned is essential for achieving the best sound. Whether you're a beginner or an experienced musician, using our free guitar tuner is simple and accurate.

STEP 1

Activate the tuner

  • Click the red microphone icon.

  • Allow microphone access when asked to enable the tuner to listen to your instrument.

STEP 2

Check your string tuning

For accurate tuning, avoid environments with too much background noise.

 

  • To begin, pluck a string on your guitar and let it sustain (we recommend starting with the lowest string).

  • The tuner will identify the note you played, and a slider will appear showing how close to the target note the string is.

    • Slider is GREEN - string is IN TUNE

    • Slider is RED - string is OUT OF TUNE

STEP 3

Adjust your tuning peg

If the slider is red, your string is either too high (sharp) or too low (flat) so you will have to adjust the tuning peg.

 

  • Slider to the LEFT of center means your string is FLAT

    Turn the peg counterclockwise until green.

 

  • Slider to the RIGHT of center means your string is SHARP

    Turn the peg clockwise until green.

 

Follow this process for each string, to make sure they are all perfectly in tune.

Tips for tuning your guitar

  • As default, the tuner is set to standard guitar tuning (E-A-D-G-B-E), but if you click on “Standard” you can access several alternative tunings.

  • Turn the tuning pegs slowly so that you don’t overcorrect or even break a string.

  • It is always best to tune up to pitch.

  • Gently stretch the strings afterwards.

  • Double-check your tuning.

What are some alternative guitar tunings?

The great thing about guitar is that there are several alternative tunings to choose from. These can open up new sonic landscapes, simplify complex chord shapes, and inspire fresh creativity in your guitar playing.

 

  • Open G tuning (D-G-D-G-B-D)

    Blues/rock vibe with gritty rhythms.

  • DADGAD tuning (D-A-D-G-A-D)

    Celtic/folk with intricate harmonies.

  • Open D tuning (D-A-D-F#-A-D)

    Resonant for expressive slide blues.

  • Drop D tuning (D-A-D-G-B-E)

    Heavier metal and rock with easy power chords.

  • Open C tuning (C-G-C-G-C-E)

    Fuller sound for acoustic richness.

  • Standard tuning with Capo

    Versatile for easy key changes.

What instruments can I use the tuner for?

The tuner is set to guitar as default. For other instruments click on “Guitar”, and you’ll find the list of options:

  • Guitar

  • Bass

  • Ukulele

  • Mandolin

  • Banjo

  • Violin

  • Viola

  • Cello

  • Bouzouki

If your instrument isn't there, you can also set it to Chromatic where it will identify any note played.

How often should you tune a guitar?

The secret to a well-tuned guitar? REGULAR TUNING! It's a good habit to tune your guitar every time you play, and even to check the tuning mid-session. This way, you can catch any strings that have drifted out of tune due to vigorous strumming or extended play.

Why does my guitar keep going out of tune?

If you find your guitar goes out of tune a lot, you're not alone. There are many reasons, such as changes in temperature and humidity, the intensity of playing styles, and the quality of components like strings, nuts, bridges, and tuning pegs. Issues with old strings, incorrect string winding, and neck movement further exacerbate the problem.
