A great piano player, playing the right material can be most interesting to appreciative musicians..
What separates the boys from the men on piano... "voicing" .. No not vocals
Not just dynamics in your playing, but how you voice a chord... yes both hands
Most of the keys on a piano (real piano) use three strings as you strike a key... this is rich in overtones..
Combine the overtones with the smart voicing of a chord... and most musicians should not be bored so easily
