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. Dadd9 has 00077x, x00770, 0047xx, 0x0770.

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