Your piano is made mostly of natural, organic materials that have been specially treated for long-term durability. Such materials react to changes in temperature and humidity, however. Frequent fluctuations in the ambient conditions may necessitate shorter maintenance intervals. They may even damage your piano permanently. Possible long-term consequences include tuning instability and cracks in the wood. You should therefore isolate your piano from the following: Outside walls without thermal insulation. Air conditioning or drafts, which may dehydrate the wood. Heaters, radiators or heated floors. Warm air may dehydrate the wood. If you place the piano on a heated floor, make sure you insulate the area directly below and around the piano. Direct sunlight, which may heat the piano’s interior, with the same effects as heating devices. Sunlight may also damage the exterior finish and bleach the wood veneers. Ideal environment conditions for your piano are a humidity range between 45 and 70%, and a temperature between 20 and 22 °C (70 to 72 °F). The more stable the environment conditions, the more evenly your piano will perform. We therefore recommend placing a hygrometer near the instrument to monitor changes in the ambient conditions.
