Each harmonic starting on page four should be read as the fret at which that particular harmonic will sound. They should also stay away from any attack or noise while changing notes. A nice even change is preferred. A volume pedal is one way to achieve smooth changes. All five guitarists should sit in a circle or horseshoe shape in order to be able to see and cue each other.
All time represented in the score is approximate.
Complete time is determined by the text and music together. I have left the dynamics up to the ensemble or the ensemble director. I recommend, however, that guitarists 4 and 5 use volume pedals to weave in and out of the texture of guitarists 1-3, especially when changing notes. The volume of the piece relies heavily on the size of the hall in which it is performed. Since various effects are employed by the guitarists, it is not possible to create an accurate representation of the desired sound.
