Anybody that has heard a guitar built by Thomas Blackshear is already aware that he builds world-class instruments, but this time it was something special. I was asked to be the Master of Ceremonies at a concert that would introduce to the world a guitar built by Tom, in collaboration with Dr. Joseph Nagyvary, a biochemist who had recently gained a great deal of attention by claiming, then demonstrating, that he had rediscovered the processes of the Cremona Masters. This, I was told, would be a Stradivarius guitar!

Naturally, I approached the matter with a mixture of enthusiasm and hardboiled scientific skepticism. My introduction to the guitar was over the telephone (yet!) and I was already quite impressed. A subsequent call from guitarist Terry Muska who told me that we would not be needing a microphone at the concert whetted my appetite further, and when I heard a preview of the instrument, all of my reservations were gone. The story really began about a year ago when biochemist, Joseph Nagyvary (Professor of biochemistry and biophysics, Texas A&M University) discovered that the wood from the Stradivari and Guarnari instruments was remarkably different from that of the more modern instruments, in that the tubes that comprise wood (xylem) were not plugged with dried pectin. Furthermore, the chemical composition of the open-tubed Cremona instruments was very different, and that the wood was much stiffer and less elastic than more modern instruments that have been built in the last 350 years.
