Stradivarius whistles may not be far off.
We’ll see how this plays out, but there’s an interesting development going on behind the scenes of wooden whistlemaking.
I’ve been exchanging emails with several of our favorite whistle makers about 1 X 1 X 12’s of specially handled dogwood. “Dogwood” is a derivative of “dagwood,” which refers to the fact that the wood is so hard, it was the material of choice for daggers in days of yore. It’s an extremely hard, smooth grained, beautiful, blond aging towards pinkish, wood that might be outstanding for whistles.
The thing about this wood that makes it especially intriguing is, a gentleman in Georgia has developed a system for harvesting and seasoning wood that manages to fool the tree into not realizing it’s been cut down. The result is wood that’s quite dramatically different from conventionally harvested and seasoned wood.
Specifically, when you cut down a tree, the moisture gets trapped in the cells, and they swell up and crush the cell walls. Then the wood dries, and the cells shrink (shrivel, really) in such a way that the cellular structure becomes distorted and the wood becomes dimensionally unstable, with all the problems of warping, cracking, etc. with which we’re familiar, and which can be disastrous for a whistle.
This wood (the process is called ESP-90) doesn’t do that. On microscopic examination, it’s different from conventional wood, as the cells are perfectly intact, just as if the tree were still living. The ESP-90 wood is virtually crack-proof in all applications it’s been tested for so far. I’ve got three whistle makers ready to build prototypes, and can barely stand the suspense of finding out what the whistles are like.
As a possible additional feature, it’s worth noting that the wood Stradivarious used has been examined microscopically and been found to be different from other wood in a way similar to the ESP-90 wood.
The last time I read anything about it (which was 15 or 20 years ago) they were still trying to figure out what Stradivarious had done to his wood that made it so different. They speculated that Stradivarious wood resonates differently because the intact cells act as microscopic resonating chambers. I’m curious to find out if ESP-90 wood sounds different in a whistle. My guess is, it will be too subtle to hear, but I’m intrigued, nonetheless.
I’ll keep you posted.
