Under the hand. 1 of the 7 shapes here sits in open position, and the first uses 1 open string with 1 left unplayed. 4 of the 7 need a barre. Together they cover the neck from the 2nd fret to the 15th.

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. BmMaj9 has x2032x, 7586xx, x-x-9-7-11-9, x-14-12-15-14-x, 7x032x.

Drop 2. A close-position chord with the second voice from the top lowered an octave. Sits on four adjacent strings. BmMaj9 has x2032x, 6404xx, xx0426, 7586xx, x-x-9-7-11-9, x-14-12-15-14-x, x4843x, xx8637.

Drop 3. The third voice from the top lowered an octave. The dropped voice becomes the bass, which is why a string is skipped. BmMaj9 has 6x042x, x4x436, 9-x-9-7-11-x, 7x863x, x-14-x-15-14-10, 10-x-11-15-12-x.

Rootless. The root left to the bass player. Frees a finger for a tension. BmMaj9 has xx0322, x4433x, xx8779, x-x-11-11-11-10, x4x332, xx4636, x5867x, x5x676.

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. BmMaj9 has x44330, 6x0600, xx0320, xx0606.

Tensions. A shell of BmMaj9, root, third and seventh, leaves a string free, and the tones that belong over it are the 11 (E) and the 13 (G#).

What kind of chord this is. BmMaj9 is a minor chord — root, minor third, fifth. minor chords on every root, and what they are for.
