I keep thinking of ways to visualise scales, and this is the latest iteration of what I’ve come up with. I call it the notes “ladder”.
The intent is that the first visual glance should convey the most important thing about a scale - the intervals between the notes in it.
The webpage is interactive - you can hover/tap on the notes to hear how they sound in the context of the other notes in the scale. There's also a guitar tab form and a piano form.
The scale it uses is the Raag Bhairav. Raagas, from Indian classical music, are not really scales, they’re more akin to Markov chains, but thinking of them as a scale is an okay first approximation (there is also a page in there which explains all these theory details further)
