In addition to my training philosophy I published on the Guitar page, I will add easy piano lessons here.
They will reinforce or explain visually and linearly some concepts that apply quickly to guitar players.
Visualizing modes, spelling chords out, and working the left and right hands together and separately.
How instruments can work together in making music and finding the spaces in time to play nice together.
Most of my piano videos will compliment something I am training on for guitar, for more advanced music students I recommend the Rocket Piano course.
