For the literal folks, forget the instrument focused upon, but see the rest, -- apparently Bach engaged this (iamafantoo).
I never heard of it and read through it.
Next chance I get I'll do my name. In our times of spying, etc., could make an interesting Code, Hahhh... Messages and instructions via music. (Was Morse Code music? : ) I love the color of music section, too... each Hz collates to a visual frequency. I love science too, -- explains a lot!
So, for the folks still hanging around, this was new to me. It can be a way for not yet instrumentally, musical folks to have a project to focus upon. What does that mean? Well, years ago I learned if I needed to learn something, I set out to "build" it. I needed to learn a new Coding Language, I built a Calculator in that language. By the end of it, that project, I knew what I needed and had something I could use, -- motivation with tacit knowledge. : )
