Bernard Greenhouse, who died last October at the age of ninety-five, was the founding member of the Beaux Arts Trio and a great teacher. He had been the owner for fifty-four years of perhaps the greatest surviving Stradivarius cello, known as The Countess of Stainlein, ex-Paganini of 1707. Last week, according to Musical America, it sold in Boston for six million dollars.
The sale “made emotional sense” to Greenhouse’s daughter Elena Delbanco, who hoped that a wonderful young talent was going to play it. This seems to have happened. It was a private sale that required her consent.
Her husband, Nicholas Delbanco, wrote a book about the instrument in which he quoted Greenhouse describing its sound: “The quality of sound is something that one wears, that adorns an individual as though it were a beautiful piece of apparel.”
In an article about Greenhouse and his cello, Daniel J. Wakin wrote in The New York Times Magazine (January 15): “In a Beaux Arts recording of Schubert’s Trio in E Flat, the elegiac opening measures of the Andante con Moto movement convey everything beautiful about his playing. The vibrato is light and warm: the notes taper elegantly. The drop in the 15th measure to a low G sounds like a cat jumping onto a carpet.”
Eric Koch’s new book, The Weimar Triangle, is available at Indigo-Chapters and in your local bookstore. 
“ex Paganini” is mysterious. Why would Paganini, a violinist, own a Strad cello?
Six million smackeroos notwithstanding, it may be that Stradivarii are not all they’re cracked up to be.

The first piece mentioned describes a serious test in which “the rigorous standards of science” were applied to the question of whether the great 17th-century instruments of Amati, Guarneri, and Stradivari are in fact above and beyond anything made since. Answer: apparently not.
The second piece, which is really about additive manufacturing, is a bit less relevant but still good fun.
It seems Paganini had a collection of fine instruments.
