this is the second redesign of sheet music I've seen in the past few years. I applaud every attempt, because it forces us to reconsider what we already know. however, as an amateur musician for the past 30 years, it's worth considering how great of an interface "normal" sheet music actually is. The same clefs and staffs are used for every instrument, so you don't have the compatibility issues that this piano sheet music would have. The only sheet music I personally can't sight read is for the cello, which uses a different clef.
