Hi there and thanks for asking!
(Also thanks to @proguitar_rckrd for posting that short triad lesson!)

I currently don't have a big lesson on this topic but I'm glad you asked about it.
The "Inversions"-lesson that you already watched covers similar things but I'll think about making a lesson focused on only triads as well.

So glad you're learning from our lessons Steve!
Have a great day!
