Always tune your guitar before playing. It is not uncommon to tune your guitar many times while playing, even sometimes in the middle of a song or between songs when playing live. If you are not tuned properly, nothing you play will sound right. Two ways to tune a guitar are using an electronic tuner and tuning the guitar to itself.
If a note is flat, it must be tuned up to pitch. If a note is sharp, it must be tuned down to pitch. It is best to always tune up to pitch so the tuning will hold. A beginner may find that it takes a long time to tune at first, but it will eventually become second nature.
*Use bass string tuning directions for all strings on guitars with six-in-line tuners like a Stratocaster or Telecaster.
When tuning a guitar to itself, it is helpful to use a reference pitch. A reference pitch may be available from another guitar, a piano or keyboard, or another instrument. If it is not possible to get a reference pitch, such as when picking up a neglected dusty guitar at a friend’s house, it is acceptable to approximate the sixth string (E) and tune the rest of the guitar using this reference pitch. If playing with another musician, make sure that both instruments are tuned to the same reference pitch. To tune a guitar to itself, play the sixth-string fifth-fret and tune the open fifth string to match this pitch. Follow the guide below to tune the remaining strings.
