Finally dove into the Berklee music theory books I'd ordered a little while ago, and, after 20 some years, I thought I might as well just start from scratch...
And it's got me thinking just how much more sense it makes to refer to notation mathematically rather than based on notes' and rests' shape or even color, like we do in french.
For example, in french, a quarter note is a "black note", half notes are referred to as "white notes", a whole note is called "round note". A quarter rest would be, IIRC, a "sigh". And so on...
Poetic I guess, but highly impractical.
The other thing this made me realize is how little I trust my brain to retain the information and to learn stuff. I'm actually quite sure that I underestimate those abilities. Underwent the same thing when I studied for my driver's licence last January...
But in the end, I suppose it only makes things more gratifying.
