Guitar Tuner

Tune an acoustic or electric guitar to standard tuning: E A D G B E, from the thickest string to the thinnest.

Standard guitar tuning

Remember it with Eddie Ate Dynamite, Good Bye Eddie. The low E is the thickest string, nearest your face when you play.

Tuning tips

• Tune up to the note. If a string is sharp, drop below the note and come back up so the gear holds.
• Electric guitar: tune with the volume knob up and play a single clean note, not a chord.
• Acoustic: hold the guitar close to the phone or laptop microphone.

Tuning by ear (5th fret method)

With low E in tune, the 5th fret of each string matches the next open string, except the G string, where the 4th fret matches the open B.
