Prism Spectral Lines on Piano Lid Beijing Stage

Midsummer dawn light spills across a glossy black piano lid resting on a festival main stage in Wangfujing. A glass prism positioned at the edge fractures the glow of distant street lamps into sharp spectral lines that stretch diagonally over the polished wood. Behind the instrument, heavy stage curtains hang in deep folds, partially obscured by a thin layer of haze that softens the background. Coiled black cables snake across the dark floor, disappearing into the shadows. The light reflects off the curved surface of the piano, creating a bright white highlight that contrasts with the cool blue and violet tones of the refracted spectrum. A final reflection of the prism's sharp edge glimmers on the wet-looking sheen of the lid's rim.
