The common shapes, written lowest string first: x3123x, x30045, 8677xx, x67788, 8-x-7-8-8-10, 8-x-10-8-10-10, x-x-10-8-10-10, x-10-10-8-10-10, 11-10-10-12-10-10, x-15-13-14-15-x.

Shell. Root, third and seventh: the guide tones fix the quality, so the fifth is dropped. That is what leaves a string free, so pick a tension to put on top. Cm69 has x3123x, 8677xx, x-x-10-8-10-10, x-15-13-14-15-x.

Drop 2. A close-position chord with the second voice from the top lowered an octave. Sits on four adjacent strings. Cm69 has x3123x, 8677xx, x-x-10-8-10-10, x-15-13-14-15-x, xx1535, 5515xx, x5754x, xx7748.

Drop 3. The third voice from the top lowered an octave. The dropped voice becomes the bass, which is why a string is skipped. Cm69 has 5x153x, x5x545, 8x774x, x-6-x-7-10-8, 10-x-10-8-10-x, x-15-x-14-15-11, 11-x-12-14-13-x, x-12-x-8-13-10.

Rootless. The root left to the bass player. Frees a finger for a tension. Cm69 has x0103x, xx1233, x6778x, x-x-12-12-10-11, x-x-13-14-15-15, x5524x, x5x243, xx5745.

Open string. An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful. Cm69 has x0004x, xx0045, 5600xx, 5x004x.

Tensions. A shell of Cm69, root, third and seventh, leaves a string free, and the tones that belong over it are the 11 (F).

The common shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
