(i'm a right-handed amateur guitarist)
The Left and Right hands are connected in the mental model used to play the guitar.
The right hand slaps strings and passes a vibration down to wherever the left hand rests.
When first starting out, the two hands operate from independent silos, but every practice session thickens the neural pathway between them.
Developing proper coordination between the two hands to create rhythm relies on the instantaneous predictive signalling from picking hand to fretting hand, immediately followed by analytical signals from the fretting hand back over to the picking hand.
When I attempt to consciously observe my experience, I visualize the process as a complex game of ping pong; also can think of the left hand shape as preparing to catch the vibration - different shapes produce different tones.
