What are the standard acoustic guitar tuning chords and how do you properly tune an acoustic guitar using these chords?

The standard tuning for an acoustic guitar is EADGBE. To properly tune your guitar, start by tuning the low E string to a reference pitch, then use the fifth fret method to tune the A, D, and G strings. For the B string, use the fourth fret method, and for the high E string, use the fifth fret method again. Make sure each string is in tune by comparing it to the reference pitch or using a tuner.
