How to Tune an Acoustic Guitar

Step 1 – Tune the Low E String

Start with the sixth string, known as the Low E string.

Play the string clearly and watch the tuner display. Turn the tuning peg slowly until the tuner shows the note E and the pitch indicator is centered.

Step 2 – Tune the A String

Move to the fifth string and tune it to A.

Play the string one note at a time and make small adjustments until the tuner confirms the correct pitch.

Step 3 – Tune the D String

The fourth string should be tuned to D.

Continue adjusting until the tuner indicates the note is perfectly in tune.

Step 4 – Tune the G String

Next, tune the third string to G.

Allow the string to ring clearly and make gradual adjustments for the most accurate reading.

Step 5 – Tune the B String

The second string is tuned to B.

Small turns of the tuning peg can make noticeable pitch changes, so tune carefully.

Step 6 – Tune the High E String

Finally, tune the first string to High E.

Once all six strings are tuned, strum a few chords and listen for a balanced, clean sound.
