Every chord in All Fourths tuning

E·A·D·G·C·F

All Fourths tuning is E A D G C F, low to high. Compared with standard tuning, the 2nd string goes from B to C (up a semitone); the 1st string goes from E to F (up a semitone). This chart gives you an easy shape for 108 chords: major, minor, power, dominant 7, minor 7, major 7, sus2, sus4 and add9, on all 12 roots.

Strings run low to high (E A D G C F). A number is the fret, 0 is an open string and x is a string you don't play. A label such as 5fr beside a diagram marks where a shape starts higher up the neck. Tap any chord to open that exact shape in the app, along with every other way to play it.

Questions

Do my standard-tuning chord shapes still work in All Fourths tuning?

Partly. 2 of the 6 strings change, so a standard shape that avoids them (it can only use the 6th, 5th, 4th, 3rd strings) keeps its fingering and its sound. Any shape that uses a changed string sounds different and needs adjusting, which is what the chart above does for you.

How were these shapes chosen?

The chord engine searches every way to voice each chord in All Fourths tuning, then these are the easiest of them: no thumb, at most four fingers, within four frets, a root or fifth in the bass, and no muted string between played ones, preferring low positions and fewer muted strings. Each card says how many other voicings exist, and tapping it opens that exact shape in the app.
