The interior panel provides a visually stimulating experience that ranges from beautiful to realistic. The panel hangs below the surface of the interior and adds a dynamic depth to the inside of an opened Keyhole piano. Bamboo veneer is standard. This and other woodgrain options from a distance simulate the strings within an acoustic piano.
The panel is usually anchored with brass screws around the edge. Other options include brass plugs for easy removal or thumbscrews for a more detailed look.
