The 9-Gamut is a great procedure to add to your regular tapping. When I first learned to tap (many years ago) the 9-gamut was always included. Now it doesn’t seem to be very common, but I still find it useful. Fair warning: it looks really weird. This was always the hardest part to get people to do and it is such a shame. If you can roll your eyes (I bet you can do that), hum a tune, and count to 5 you can do this. Keep an open mind and give it a try.
