Well, I have a Roland F-100 which is a digital piano (as I'm sure you could tell by the tone). I've found there's something wonderfully intimate and private about a digital piano. If you want, nobody else in the world can hear your music, just you....or just you and at least one other person =). Yes, I improvised it for her. She requested it. Amusingly, I didn't even feel like playing that day.
