‘Incidental music is often background music and adds atmosphere to the action. It may take the form of something as simple as a low, ominous tone suggesting an impending startling event or to enhance the depiction of a story-advancing sequence. It may also include pieces such as overtures, music played during scene changes, or at the end of an act, immediately preceding an interlude, as was customary with several nineteenth-century plays.’ – Wikipedia
Nocturnal Spaces, like incidental music, fill the background space of the conscious mind. Wandering through the nightscape the landscape changes radically, no longer informed by lines delineated by daylight, contours merge into vastly different realms, ones where subconscious thoughts leak out into nocturnal spaces.
