Instructions
1. Start with your guitar tuned to standard tuning: E A D G B E (low to high)
2. Lower the pitch of the low E string one step to D. This string should now match the tone of the adjacent A string, fretted on the 5th fret.
3. Lower the pitch of the low A string one step to G. This string should now match the tone of the adjacent D string, fretted on the 7th fret.
4. The D, G and B strings remain the same as in standard tuning.
5. Lower the pitch of the high E string one step to D.
6. You may need to re-tune your strings a couple of times until they settle into the new tuning. Using an electronic tuner or piano can help you achieve an accurate tuning.
