How To Use

Modewheel is a reference tool for quickly finding the notes of any mode in any key. Rotate the wheel so the mode you want lines up with the starting note you want, and all the visible notes are the notes of that mode.

For example, if you want to know the notes of E Dorian, rotate the wheel 60 degrees, so Dorian is lined up with E, and there you have it. The only visible notes will be those of E Dorian.

Use the dropdown menu to select a different scale. More scales will be added over time.


This is the second version of the modewheel. It is a proof of concept, really, but it also started out as a JavaScript exercise. It was intended to work on Android devices, and is available through the Play Store right now, but I need to rebuild it in Java, which I'm learning.

I must also thank my friend David M for helping me with the idea. Initially, this was going to be a horizontal 'infinite' sliding widget, but he suggested it should be round, so it could be printed out and used. I figured that's also a pretty good form factor for online/mobile use, and so here it is.
