The ninth string typically gives new and intermediate players some problems.  This lesson is what is taught in the live seminars on how to get the most out of your tuning by incorporating the ninth string into your playing.  I look at the ninth string as used in five different ways: 1. as a dominant seven 2. as a root  3. as a major third 4. as a minor third  5. as a sixth.  Use this lesson to open your playing p to many new possibilities and increase your chord vocabulary.
