Instrumental only, solo felt piano, warm and muted

Instrumental only, solo felt piano, warm and muted sound, single-note melody only, strictly no chords and no arpeggios. Tempo around 56 BPM. Relaxing and reflective mood like watching rain at night. Sparse note placement with longer gaps between phrases. Very soft velocity, rounded attack, low brightness. Narrow melodic range, mostly stepwise movement with occasional small interval jumps. No drums, no bass, no pads, no strings, no violin, no wind instruments. Very minimal arrangement, loop-friendly structure for long relaxation playback. Gentle room reverb, low mix level, no dramatic dynamics, stable and calm throughout.
