I started a cello on Christmas morning 2013. It’s a new model for me. A forma B Stradivarius based on the Countess of Stanlein, played for many years by Bernhard Greenhouse of the Beaux Arts Trio. Previously I’ve used a Guadagnini model. Shorter and wider across the C-bouts. I used to consider the forma B a bit on the narrow side, but as with most things Stradivari, I’ve come around.
