I was self taught on piano for years, and when I finally started taking lessons I had so many bad habits to break that were holding me back. Reading notes was not the problem, but my technique for how I was physically striking the keys needed a lot of attention. Legato, phrasing and dynamics are the real challenge and it’s tough to practice things with such subtlety on digital keyboards at all. I still do it, but every time I play on a real piano I have to recalibrate. The author says he chose a piano without weighted keys, I think that’s ultimately not the right choice if you are truly interested in learning piano and eventually want your skills to translate to a real piano. Pretty early on the proper technique is based on weighted keys.
