That's true. I played some piano before I started on the guitar but quit cause it was boring. My parents kind of made me play. But after finishing this first-year music theory class I just took, it's really easy to sit down and play the piano. Visually, it's easier to see everything. Almost any instrument is easy to play once you spend a few minutes re-orienting yourself to the different physical aspects of it. In fact, I've become interested in a lot of unusual ones like the ocarina, lute, harp, piccolo, or anything else in Celtic or medieval music. The relationship between the notes is the same on any instrument.
