In order to play along with other musicians in a band or to play along with a song on the radio, all instruments must be in tune with each other. There are many methods of tuning a guitar, but the easiest is to use some sort of guitar tuner. Here is a picture of my trusty old Seiko tuner. I have had this one for many years and it still works well.

In case you do not have a guitar tuner yet or perhaps you just don’t have one handy, I have created on online guitar tuner that you can use for free. Just click the buttons below to hear a properly tuned guitar string. For the beginning students, remember that the 6th string is the fattest one at the top of the guitar.

This Guitar Tuner page works in a pinch, but it is worth the price to invest in your own tuner so that you can tune more accurately.
