Instrumental only, solo felt piano, very soft and intimate tone, single-note melody only, no chords, no arpeggios, no harmony layers, no decoration notes. Tempo around 56 BPM. Calm, night-to-dawn relaxation mood. Each note spaced with natural silence, long tail reverb but low in volume, no bright high frequencies, no sharp attack. Melody simple and memorable, stepwise motion, narrow pitch range. Loop-friendly structure for long playback. No drums, no bass, no pads, no strings, no violin, no wind instruments. Minimal dynamic change, emotionally warm but restrained. Designed for relaxation and background listening.
