Online Guitar Tuner

Use this free online guitar tuner to tune your guitar. You may use this to tune any type of guitar that has 6 strings such as an acoustic, electric, or even classical guitar. For a guitar with 12 strings visit our 12-String Guitar Tuner. This is initially set for the standard EADGBE guitar tuning. If you need a different tuning you may adjust the notes to your liking, or use the presets on the right. For other methods on how to tune your guitar go to our Guitar Tuning Methods page. See instructions below the tuner for usage.

Instructions: To tune your guitar, first you need to know what tuning you want the guitar to be in. The standard tuning for 6 string guitars is EADGBE. If you want to tune it in standard form then you don't have to change any of the notes above, because it is initially set to EADGBE. If you want a different tuning then try some of the presets on the right side of the guitar tuner. If you don't find the tuning your looking for then you have to adjust the notes manually. Once you have set up the notes and have the correct tuning. Then click on the buttons one at a time and then tune your corresponding guitar string to the note. The thickest string on the guitar is the 6th string, and the thinnest is the 1st string. It tells you what string it is on each button. Also, be careful on how high you set the notes, because I have included notes on the tuner that would probably snap average guitar strings. Good luck.

Hal Leonard Guitar MethodTip: Make several passes tuning each of the strings. For example you might have noticed that if you have tuned all the strings once, and then back to the first one you tuned, it might be off a little bit. This is because you are increasing or decreasing the tension on each of the strings as you tune it and the instrument's body might bend ever so slightly due to this difference in tension. This causes the other strings to slightly change in pitch. So make sure you keep on checking and tuning the strings until all are in tune, so make several passes. See more tips at the Guitar Tuning Tips page.

Now that you have your guitar tuned, you can get to playing it. The Hal Leonard Guitar Method is a great learning resource for those who are learning to play the guitar.
