I like that saying.But please tell me I don't have to lick the piano in order to learn to play it.
You must invent that piano! And it must come with perfume, and a different texture on each key: furry, sandpaper, cold, warm, bumpy ......But more seriously, I once told somebody that I discovered that the piano is a giant marshmallow and they understood. If you think of the behaviour of the keys, does that make sense to you?
Ah, no. The piano has the squooshiness and textures of a marshmallow so that you can sink into the notes for all their nuances. The other person, a teacher, understood, and wrote two long paragraphs explaining why the piano is a marshmallow. Unfortunately the digital piano is a very poor marshmallow, and somebody else's voice is in there so that my own can barely be heard.
Digital is just a tool to develop skills to read and play music.
... and to turn off the ears.
Also, when kids learn how to draw or paint we don't give them the finest and the most expansive colors or pencils that made for professionals simply because they won't notice any difference and just want bright colors!
