Every chord in Open C Minor tuning

C·G·C·G·C·Eb

Open C Minor tuning is C G C G C Eb, low to high. Compared with standard tuning, the 6th string goes from E to C (down a major third); the 5th string goes from A to G (down a whole step); the 4th string goes from D to C (down a whole step); the 2nd string goes from B to C (up a semitone); the 1st string goes from E to Eb (down a semitone). This chart gives you an easy shape for 106 chords: major, minor, power, dominant 7, minor 7, major 7, sus2, sus4 and add9, on all 12 roots.

Strings run low to high (C G C G C Eb). 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.

No easy shape: Abm7, B7. The engine finds voicings for these, but none that avoid a thumb, a wide stretch or a muted string in the middle; each card links to all of them in the app.

Questions

Do my standard-tuning chord shapes still work in Open C Minor tuning?

Partly. 5 of the 6 strings change, so a standard shape that avoids them (it can only use the 3rd string) 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.

Why are power chords easier in Open C Minor tuning?

The bottom three strings are tuned C, G, C, which is a root, a fifth and an octave. Barring them at any one fret gives you a power chord with a single finger, so it is faster to move and to mute than the two-finger power chord in standard tuning.

How were these shapes chosen?

The chord engine searches every way to voice each chord in Open C Minor 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.
