How important is wood seasoning?

A freshly cut log can contain 80 percent of it's weight in water. Most of this water must be removed to meet the environmental conditions where where the final product will be used; otherwise, the piano or fine furniture will develop cracks or failed glue joints.

The process of removing this water is called seasoning.
While each species of wood varies, the average Equalized Moisture Content (EMC) in the United States, for seasoned lumber, must be in range of 6 to 8 percent.
In the United States, most pianos will be subjected to the effects of central heating and air conditioning.
A piano that is not properly seasoned will likely develop problems. If the air is drier than the piano, the piano will give up moisture, the lumber will shrink, and crack, the finish will deteriorate and the tuning will suffer. "Colorado is particularly difficult on pianos due to it's extreme dryness," says specialist, Charles Daeschner.

Yamaha Seasoned For Destination

Yamaha specifically seasons all pianos destined for the United States market.
Seasoned for destination means lowering the EMC of the wood before manufacture to match
the driest condition the piano will face in that final destination. It does not mean that the pianos are individually seasoned for a particular city, but for the worst condition in the entire destination. (USA)
Yamaha is acknowledged as a leader in the field of wood technology.
Starting with the log, Yamaha is in complete control of all wood processing.
Yamaha has it's own holding lakes, lumber mills, outside seasoning yards, computer-controlled kilns, and air conditioned factories.
This "seasoning" ensures that the final piano product will withstand the climactic conditions during the piano's lifetime.
