Blue Hour For Deep Sleep

This piece is built around one long, unbroken piece built from a single recording, with one warm low tone holding steady beneath quieter melodic lines that move slowly above it, and a gradual, wordless disappearance at the end. It is made for drifting toward sleep, and it stays in one place rather than building toward anything.
The atmosphere is a deep, calm blue-hour twilight, still and unhurried, with one sustained instrumental recording, recomposed into long overlapping passages carrying the sound. There are no abrupt shifts in volume and no sharp transitions, so it holds an even shape from beginning to end, across roughly 55 minutes. There is no narration and no spoken word at any point.
It may suit you if you are bedtime, night waking, or a long night that needs company. Use it at whatever volume lets it sit behind your attention rather than in front of it, and let it run for as long as you need. Listeners often reach for this kind of sound for deep sleep, night, calm and rest.
