I hadn’t seen musical intervals used to express ratios between things that weren’t pitches, but I think it’s an interesting idea. I guess all they really are is a nice name for specific ratios, so it makes sense that they could be useful in more contexts. Has anyone seen them used in other interesting contexts?
