Last week, I was in France for a wedding, and a side trip took me to the Loire Valley. While walking along the river in the charming town of Blois, I caught sight of two swans gliding upstream. The Loire has a swift and strong current, so I knew the swans had to be paddling furiously under the water’s surface, but up above it, they maintained a completely calm, beatific look. I thought of one of my favorite words, sprezzatura: the ability to make a difficult task look easy. And that put me in mind of one of my favorite trombone players, Joe Jackson, who is conveniently in my jazz band. Two months ago, Chaise Lounge played a concert with the Pan American Symphony Orchestra, and one of the pieces on the program was Astor Piazzolla’s “Oblivion,” with Joe playing the solo usually performed on violin. This beautiful, impossibly high lyrical piece would leave most trombone players in tears, but for Joe, it seemed effortless. Of course, I knew his “effortlessness” came from 30+ years of devoted attention to his craft. But the best players, like swans swimming gracefully upstream, can make you forget everything but that beautiful performance.
