Watch the ii7 and V7sus4 online guitar lesson by Brad Carlton from Guitar Lab: ii V I Options

This lesson addresses the relationship between the ii7 and the V7sus4. This is an important concept to understand because it allows you to get extra mileage out of any ii7 voicing.

Commit this information to memory:

V7/6sus4 = ii9 (no 5) / V
V9sus4 = ii7 / V
V13sus4 = ii9 / V
