Watch the A Minor (Special) Progression online guitar lesson by Tierra Negra from Magic Gypsy Chords & Rhythms

We call this progression "The Secret".
The capo is placed at the 2nd fret.

This cadence belongs to the most beautiful and mysterious chord progression I know. And the best of all, it's easy to play. I'll tell you the secret, you have to tune down the G-string to F – only with this tuning will you unlock the mystery. So if you put your 3rd finger on the D-string in the 5th position (capo 2nd fret!), the open G-string and the D-string sound the same.

If you were playing without the capo, we would be in the key of A-minor, but actually the cadence sounds like in the key of B-minor, because we have the capo at the 2nd fret.

I play the following arpeggio pattern, but please notice that there is a little variation in the arpeggio in the last bar (last chord).
