The series of chords is finite because it begins and it ends. The repeat goes back to the beginning; the double bar marks the ending. Play in the most intimate and fragile, slow and subdued manner. The length of the chords is uniform. Any instruments or voices of any combination may perform this. Wait ever so slightly and lightly between the chords, with the waitings being uniform. Chords may not overlap. At least two instruments play in each chord one of the tones. If there are 3 players, try playing as many of the chord tones as possible given what your instrument or voice is capable of. If there are 5 players, when everyone plays there will be notes that are doubled or tripled (or more) in each chord; listen carefully and balance the voicing so that the color and blending of sound is always the focus. Unisons are allowed. Vibrato should be minimal to none. The series may be repeated as many times as the moments speaks to the performers.With each repetition, players play in fewer and fewer chords.
