"In the 1690s Stradivari must have been aware of these smaller cellos because he made a change and dropped down a size. The Castelbarco is an inch smaller than the very big cellos, and the stop is halfway back to normal, about 16.25 inches. . . . This instrument wasn't made for what we consider cello music today. It looks like a cello and we call it a cello, but when it was made, it was still playing mainly bass lines as part of a continuo."
