What is standard tuning for a 12 string guitar?
Tuning a 12-string guitar in standard E tuning (E-A-D-G-B-E, thick to thin) is very common. To tune your 12-string, tune the E, A, D, and G string pairs within an octave of each other. For the remaining high B and E strings, tune their string pairs in unison to the same frequency.
Should I tune my guitar to drop D?
Before you tune your guitar to drop D, you'll need to tune it to standard, E, A, D, G, B, E tuning. To get your guitar precisely tuned, you should always tune it with an electronic tuner first. Once in drop D, you'll be able to play power chords easily and can cover songs that were written in drop D.
