What is tuning down a whole step?

Tuning down a whole step / whole tone / D tuning

This tuning allows you to get that low bottom end D in, but as part of standard tuning intervals, so you can form all the chord shapes you're used to, especially open chords, and get that deeper atmosphere.

How do you tune a whole step down with a capo?

Here's a trick to get around it:

1. Put a capo on the 2nd fret (if you don't have a capo, just make sure you're fretting the 2nd fret each time to pluch the string)
2. With the capo (or finger) in place, tune the guitar as normal. ...
3. Remove capo (or finger) and voila, full step down.
