They should be switched.

Cool project, I was looking to play around with the Camelot wheel and this repo gave me some ideas. Thanks!

Thanks! I will research this. I have to find the documentation (or was it a youtube video) where I got this from.

Or if you have a link directly, that'd be helpful too.

There are twelve notes in the chromatic scale: A, A#/Bb, B, C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, and G#/Ab. "Half step" and "whole step" Camelot modulations refer to changing to a key signature whose root note is one/two steps (respectively) above the root note of the original key. So for Ab minor (1A), a half step in either direction would be G minor (6A) or A minor (8A); a whole step would be F# minor (11A) or Bb minor (3A). So on the wheel, a half-step modulation is +/- 7, while a whole step modulation is +/- 2.

Perhaps an article on the chromatic scale would be helpful; everything else is in the Camelot wheel. Here's a good article on key changes using Camelot wheel terminology and explaining a bit of theory.

Yeah, they're reversed.

A "Semi-tone" is one key up on a piano, but with that selected for "A" it gives "B" as the higher note, but that's two semitones; "B♭" (aka A#) is in-between those, but that is what shows as the higher for "Double Semi-tone".

A better label IMO for "Double Semi-tone" would be "Whole Tone".
