It's all nice that theres a grid pattern and 2 cameras, one on the teacher and one on the teachers hand but the camera that shows the hand is absolutely useless from the angle and distance its recorded in. Almost makes its comical to watch and wonder what's the point of seeing a 2d flat angle of a hand over a fretboard barely making out the movement.
Ineffective to say the least.
A simple fix would just be to add numerical count inside the grid pattern so we have something other then her vocal instructions..
