Now lets take a look at the minor shapes. A C minor chord is
C, Eb, and G. Just take all of the major shapes and lower the
E to an Eb.
You can see that the Eb didn't make this shape any more comfortable.
Don't bother with it.
All of the previous major and minor shapes could be played on
the 3rd and 4th strings, 4th and 5th strings and even the 5th
and 6th strings.

the chord or arpeggio).
