Under the hand. 1 of the 10 shapes here sits in open position, and the first uses 2 open strings. 6 of the 10 need a barre. Together they cover the neck from the 2nd fret to the 14th.
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. Em69 has xx2022, x7567x, 12-10-11-11-x-x, x-x-14-12-14-14, x7x022.
Drop 2. A close-position chord with the second voice from the top lowered an octave. Sits on four adjacent strings. Em69 has xx2022, 2420xx, x4405x, x7567x, 12-10-11-11-x-x, x-x-14-12-14-14, 3746xx, xx4653.
Drop 3. The third voice from the top lowered an octave. The dropped voice becomes the bass, which is why a string is skipped. Em69 has 2x202x, x4x052, x7x673, 3x465x, 9x597x, x9x989, 12-x-11-11-8-x, x-10-x-11-14-12.
Rootless. The root left to the bass player. Frees a finger for a tension. Em69 has xx4423, x2402x, xx5677, x-10-11-11-12-x, x2x022, x4x473, x4547x, x9968x.
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. Em69 has 004423, 0x5677, 04547x, x45470, 00402x, 044000.
Tensions. A shell of Em69, root, third and seventh, leaves a string free, and the tones that belong over it are the 11 (A).
