Are these really lists of people who aren't serious "PIANISTS", or those who aren't "serious" about piano??
Because, I think that a person can be "serious" about learning how to play the piano, but just simply doesn't know (yet) all of the theory, composers, pieces, fingering, etc. IN onther words, I think that a person can be serious about learning, but simply isn't "educated" in a lot of piano techniques, skils, and history. But that doesn't automatcially make someone "uninterested" or "not serious".
Plus, I've always wondered what the real definition of the word "pianist" is anyway. Is this someone who has been playing piano for 10 years+, competes in competitions,knows music theory, and can play difficult pieces well? OR, is a "pianist" simply someone who just plays piano?
I know these questions may sound silly to some (sorry!) but I'm new to the whole piano and music theory area. I've had private lessons before, and have had a piano in my home since I was 3, but I"m still struggling with music theory and sight-reading. So, I guess you could say I'm a beginner. :-/
