I'm asking what makes sheet music any more information than recorded music. Are you trying to say that I'm somehow calling an airport restroom, a freshly cut flower, and a brand new car information? Or are you just disqualifying me from the conversation as a rhetorical trick to avoid answering a simple, straightforward question?
I thought I detected you heading in that direction. Yes, people do try to make that argument.
Sheet music is like an instruction manual. Follow the instructions, you can make something. I consider instructions to be information. Recorded music, on the other hand, is a performance. A performance is art, while sheet music describes art?
I don't have technical definitions, this is just how I see it.
