Accordion in velvet case under theater blue dusk light

Warm sodium-vapor glow washes over a wooden accordion resting inside an open instrument case lined with deep red velvet. The stage floor of the Cúcuta theater reflects the humid air left by the recent wet season rain, creating a slick sheen under the instrument. Fine white rosin dust hangs in the beams of the rehearsal lamps, catching the fading evening light. The case lining shows subtle wear along the edges where the velvet meets the hard shell. Outside the stage area, the sky holds a deep blue hue, against the amber artificial lights. One strap hangs loosely from the instrument, resting against the soft fabric, while the polished wood of the keys gleams under the sodium glow.
