Online Guitar Tuner
With the Online Guitar Tuner you can tune your guitar in seconds. Just turn on your speakers and press the button under each note.
Turn your guitar's machine heads (AKA tuners, peg heads or tuning pegs) to a higher or lower note until obtaining a "note match" with the tuner's sound.
If you have just changed your guitar strings it is wise to stretch them before tuning to avoid the guitar from going out of tune frequently. It is recommended to repeat this process 2 to 3 times as the tuning of one string causes the tension of the other strings to vary and get out of tune.
To use this tuner simply press the button under the note that represents the string you want to tune. The letters from left to right (E-A-D-G-B-E) are your guitar's strings from top to bottom (6th-5th-4th-3rd-2nd-1st). NOTE: The note continues to sound until you press that button again or choose a different note.
