How to Tune a Guitar Online
Standard guitar tuning is E2-A2-D3-G3-B3-E4, written EADGBe (the lowercase e is the high string). Our online guitar tuner detects whichever string you play and shows how far off pitch you are. Click a string letter to hear the reference tone, then play that string on your guitar and turn the tuning peg until the needle centres. Repeat for each string.
