Here is a pretty neat riff that is in drop D tuning. In drop D tuning, the
low E string is tuned down one whole step to D. This enables the guitarist
to play power chords with a single finger. If your favorite band uses drop
D tuning and you want to experiment with this tuning, by all means do so. What
ever you do, don’t learn the guitar in drop D tuning-you’ll get all mixed up.
To tune your guitar to drop D tuning, first make sure your tuned to standard
tuning. Then you’ll want to tune your low E string down two steps to D (we
drop it down one step, hence the name). See the picture below. You can use
the audio clip below to tune your low E string to D for drop D tuning.
