[I don't read music.] From stories/videos I've watched on the topic, musician's don't so much read absolute notes but notes of a scale. A trained one knows their scales and can represent them with the letters A-G once each, using sharps or flats as necessary. I'd also expect them to know exactly where each note name/sharp/flat is on the instrument they play.

There's also an affinity for piano being a sort-of reference instrument pertaining to mapping of scales as it has the least idiosyncratic placement of notes compared to other instruments.

What about a scale that has lines for the white keys of the piano and larger spaces where black keys appear would be 1:1 with piano, but there would be too high a density of lines.

So how about we make the black keys the lines and we can have single spaces for single white keys and double spaces where two white keys intervene the black ones? That almost makes sense as the lines are black and the page/spaces are white.
