How many times have you visited a friend’s home and found a piano next to a window? Perhaps you have a piano in your own home that is in front of a window or unshaded French doors. While the view of a piano against the backdrop of nature (or the city skyline) is a romantic and popular vision, this placement can be harmful to the instrument due to prolonged exposure to direct sunlight.
There are several ways direct sunlight can affect a piano:
- Fading: Prolonged exposure to UV rays from direct sunlight can dull your piano’s finish over time.
- Warping: The wooden parts of your piano can begin warping with continued exposure to heat build-up from direct sunlight. Not only can this affect the instrument’s appearance – it can also impact playability.
- Drying: Drying can create problems with sticky keys and sluggish action.
- Temperature: Sunlight can make the room hotter. This can in turn cause fluctuations in humidity levels. Approximately 42% humidity is best for helping stop warping.
- Static electricity: This one may surprise you, but prolonged direct sunlight exposure can cause a buildup of static electricity. This could have an impact on keys and internal components.

So, how does one protect a piano from the detrimental effects of prolonged exposure to direct sunlight?
The obvious steps recommended by piano makers and tuners include keeping the instrument in a climate-controlled environment, away from direct sunlight, and using a piano cover. They also recommend window treatments.
Window shades are a perfect way to reduce direct sunlight exposure, not just for pianos but other valuable furnishings as well. Window shades can:
- Prevent UV rays from getting to your piano.
- Stop heat buildup by filtering or all together stopping direct sunlight penetration.
- Maintain natural views for aesthetic benefits while alleviating glare.
- Be part of a humidity control plan by helping regulate temperature changes during the day.
For the best results, shades should be motorized and automated. By adding a sun tracking system like TourneSol, you can maximize protection on multiple windows throughout the day.
