Solo acoustic grand piano, very slow tempo (48 BPM

Solo acoustic grand piano, very slow tempo (48 BPM). Strong deep bass presence, resonant low register. Warm, dark tonal color, focus on lower octaves. Sparse mid-range chords, almost no high notes. Melancholic, dignified and serious atmosphere. Very minimal melodic movement. Long sustained low notes with heavy natural pedal. No arpeggios, no bright tones, no cinematic build. No percussion, no strings, no vocals. Intimate documentary style podcast intro, 25–30 seconds.
