About Guitar Tuning

Standard tuning (EADGBE) is the most common guitar tuning, used in the vast majority of music. Alternate tunings change the pitch of one or more strings to create different chord voicings, enable slide guitar, or achieve a heavier tone.

Tips for Tuning

Always tune up to the target pitch, not down, for better stability
New strings need to be stretched before they hold tune
Check tuning after using a capo, as it can bend strings sharp
Temperature and humidity changes affect tuning
