One total length for wavelengths in pitch staircase? (with some partition at repeat points)

[pikurasa]

I showed MB to a school teacher who is going to do a curriculum of physics and sound this fall. She said that her initial confusion about pitch staircase is that she thought the horizontal length (i.e. East <--> West) of the box might represent a length of time (and thus the higher frequencies she thought also meant they were played for a shorter length of time).

She thinks that, instead, all the horizontal lengths could be the same, but have some partition (like a red dotted line, for example) to show where and how often higher frequencies repeat in relation to the lower frequencies.

This opens the question "what is the default for the lowest tone, the length that would fill the entire horizontal length of a screen?" My hunch would be 55, which is a low A note. Lower pitches would just "burst" outside visual area with some warning. That being said, the details should be discussed and refined.
