Guitar tuning is the process of adjusting the tension of the strings of a guitar so that they produce the correct pitches when played. The standard tuning for a six-string guitar is EADGBE, from lowest to highest pitch. This tuning is used for a wide variety of musical styles, including rock, pop, country, and blues.
There are a number of different ways to tune a guitar. One common method is to use a electronic tuner. Electronic tuners are small, handheld devices that emit a reference pitch that you can match the pitch of your guitar strings to. Another method is to use a tuning fork. Tuning forks are small, metal forks that vibrate at a specific pitch when struck. You can use a tuning fork to tune your guitar by matching the pitch of the fork to the pitch of the corresponding string.
