Sleep music — soft, slow, harmonically static. Felt piano plays a sparse melody at the start, then gradually thins out. Ambient pads sustain the chord underneath. A distant cello drone holds the bass. Some tracks layer in gentle rain or ocean texture for a natural mask. Tempos crawl at 40–60 BPM in C major and A minor, with the harmony barely moving. Phrases are long, melodies fade rather than resolve, and dynamic peaks stay below conversational level.
Adults loop it through full-night bedtime sessions. Parents use the gentler cuts to settle babies and toddlers. Insomnia sufferers play it under sleep-meditation voiceovers. Meditation-app developers bundle it into deep-sleep programmes. Hotel-room and spa creators bed it under late-night wind-down videos. Also fits yoga-nidra sessions, evening journaling, and long-haul flight playlists. See also calm or ambient.
