This piece represents the translation into musical parameters of the physiological elements of the sleep cycle phases, reading an hypnogram as a score for electronic music and a score for structure. The hypnogram is used as a guide to build an algorithmic composition where the descriptions of the elements proper to the electrical activity of the brain for each phase, provides a set of electro-acoustic elements, processes and sound modifiers, at the same time suggesting the nature and the type of the sound material used in those processes.
