Pop music is rejecting the piano. Why?

Because, for whatever reason, when you put a brush on a canvas, or clay on the wheels, or you hands on a big Steinway, some piece of you hums along with the medium and capturing that resonance is what art is.

It's all sort of idiosyncratic at the end of the day, and how the thing feels in your hands is a big component of the artistic/creative process. If it works for you, it works. If it doesn't, try something else.
