Bell decided to begin with "Chaconne" from Johann Sebastian Bach's Partita No. 2 in D Minor. Bell calls it "not just one of the greatest pieces of music ever written, but one of the greatest achievements of any man in history. It's a spiritually powerful piece, emotionally powerful, structurally perfect. Plus, it was written for a solo violin, so I won't be cheating with some half-assed version."
Bell didn't say it, but Bach's "Chaconne" is also considered one of the most difficult violin pieces to master. Many try; few succeed. It's exhaustingly long -- 14 minutes -- and consists entirely of a single, succinct musical progression repeated in dozens of variations to create a dauntingly complex architecture of sound. Composed around 1720, on the eve of the European Enlightenment, it is said to be a celebration of the breadth of human possibility.
If Bell's encomium to "Chaconne" seems overly effusive, consider this from the 19th-century composer Johannes Brahms, in a letter to Clara Schumann: "On one stave, for a small instrument, the man writes a whole world of the deepest thoughts and most powerful feelings. If I imagined that I could have created, even conceived the piece, I am quite certain that the excess of excitement and earth-shattering experience would have driven me out of my mind."
So, that's the piece Bell started with.
He'd clearly meant it when he promised not to cheap out this performance: He played with acrobatic enthusiasm, his body leaning into the music and arching on tiptoes at the high notes. The sound was nearly symphonic, carrying to all parts of the homely arcade as the pedestrian traffic filed past.
