Picking a chord
If you've ever been confused about the circle of fifths, this might help.
The left stick Left stick moves around the chord wheel. The wheel has six wedges, and each holds a chord in your key. Point the stick at a wedge to arm that chord, so the next strum plays it.
- Pointing at a chord doesn't play it. Move the stick around as much as you like. The chord plays when you strum.
- Letting go of the stick keeps the chord armed, so you can keep strumming without holding the stick in place.
- Push the stick firmly to change chord. Drifting near the edge of a wedge doesn't change it.
Layout
The wheel is laid out by function. The tonic is at the top, with its two closest related chords either side of it, and the secondary chords are underneath. In C Major that's F, C and G along the top, and Dm, Am and Em below.
Every wedge shows its chord name and its numeral, so the layout is the same in any key.
Your key
The key sets which chords are on the wheel. Pick a root and Major or Minor in the header at the top of the window to put that key's chords on the wheel.
