Wood as it dries after it is dead takes on an internal tension. The fibers are stretched and being interlocked, pull on each other, creating tension. You can see this internal tension (evidence) when you run a board through the table saw and the gap of the cut is getting wider. Without this tension, wood does not transmit sound well. Wet or green wood does not transmit sound well (this may or may not have anything to do with the theory). Different wood has different tension. Milling process can release the tension. It is designed to make the wood stable. That is one reason spruce is flat sawn for soundboards.
