I'm experimenting with this variant of the clock-position, number-keys layout:
[T] = 12 o'clock
[Q] - [R] = 8 o'clock - 11 o'clock
[Y] - [ ] ] = 1 o'clock - 7 o'clock
This is a shifted version of the same layout, with 'T for twelve' as a mnemonic. The advantage here is that the break is between C#/Db and G#/Ab rather than between C and G or between F and C. This way, the similarities among the C, F, and G triads are not obscured. Chords containing both C#/Db and G#/Ab aren't introduced until very late in the game, so I'm not too worried about that.
Edit: Coincidentally, the break occurs at just the spot where the solfege syllables represented by the icons change from sharps (C# = Di = deer) to flats (Ab = Le = ladybug).
Edit #2: Here's what I mean about how the similarities among the C, F, and G triads are shown:
Code: Select all
G D B
C G E
F C A
