<< what level of math is necessary to understanding the concept of scaling, and other more advanced aspects of piano technology? >> Scaling? no more difficult than falling off a a Logarithmic. More advanced? Physics is where you put your finger on it. Metallurgy with its Inorganic chemistry?, want to begin casting a plate, do you? Most of my piano math is calculating where I left my reading glasses as I stand in a customer's driveway, at my car, in front of my stringing kit, trying to read the little Starrett micrometer that was such a deal 28 years ago. Everything else has lumped into 88 or its derivatives and after too much hammer hanging, key bushng, though occasionally the 52/36 concept floats out for more complicated stuff.
