 Now, as in study number one, you have enough scales to work on all of the pentatonic scale/chord studies in one key.  Try this. We will still be using  the key of E minor.

In E natural minor (the Aeolian mode) the chords are E minor, F# half diminished, G, A minor, B minor, C, and D.

First play the chord then the corresponding scale.

Just for the sake of it (I'm never really sure when to turn around in these lessons since I am not familiar with your guitar) I'm turning around now.  We'll go down the neck to the B minor at the 2nd fret before turning around again and heading back up the neck to where we started, E minor.

You don't have to follow this particular example.  If you can, it's better to play up the neck as high as you can go and then come back down.  Here, I showed you a typical example that an acoustic guitar player might use.  In any case, make sure to include only these chords which are in the key of  E minor (G major): E minor, F# minor b5, G, A minor, B minor, C and D and then go on to work it out in other keys.
