Watch the Tuning online guitar lesson by Vicki Genfan from 3D Acoustic Guitar
For the entire first section, we'll use what I call a Dsus tuning:
Refer to the Tuning Guide in your tool kit for help if you need it. This will show you how to tune with a tuner and without a tuner using your 'ear'.
We will change 3 strings - 6, 2 & 1
Tuning Tip - Try playing the 12th fret harmonic when using a tuner - I often get a better response this way.
