ぐっすり眠るためのBGM

Style: Deep Sleep Ambient × Lo-fi Forest Dream Tempo: 60–65 BPM (slow, heartbeat-like flow fading into stillness) Instruments: soft detuned piano (very low velocity, distant reverb), deep sub-bass drone, analog tape hiss with gentle flutter, faint forest ambience (leaves, distant birds, occasional owl hoot), warm airy pads with long release, and light wind textures Features: Gradual fade-in like sunrise through mist → sustained pads and sparse melodic fragments drifting in and out → occasional environmental sounds for organic realism → slow natural fade-out into silence Mood: Deeply tranquil and meditative — a sun-drenched forest where even the owl sleeps, and time feels suspended between breath and dream, Length: about 3min

Style: Lofi Sleep Ambient × Aqua Dreamwave (Instrumental) Tempo: 76 BPM (slow, fluid pulse) Instruments: warm detuned pads, soft sine bass, brushed percussion with felt taps and rim clicks (no kick), mellow electric piano, reversed bell tones, faint vinyl hiss and ocean ambience, Features: smooth fade-in → gentle brushed rhythm → calm bell echoes → slow fade into silence, Mood: tender and weightless — each sound feels softly touched underwater

Style: Minimal Sweet Sleep Ambient × Honey Drone Tempo: 56–62 BPM (very slow, almost floating) Instruments: ultra-soft analog pad with slow filter movement, warm sine-wave drone, very low-volume electric piano felt tones (no attack, long tail), rounded sub-bass drone felt more than heard, subtle tape warmth Features: Catchy instrumental intro as a single pad bloom, extremely sparse note changes, no bells, no music-box, no arpeggios, no rhythmic clicks, slow breathing-like swell, harmonic sweetness from gentle major or add9 chords, no builds, no drops, seamless loop feeling Mood: honeyed calm, safe stillness, afternoon sleepiness, melting awareness
