Four years ago, the classical music publishing giant, Gramophone, created a list ranking twenty of the world's best orchestras. That list has garnered many reactions, both positive and negative, from classical music fans from around the world. Many orchestras were missing from the list, while others were ranked incorrectly - or at least that's how many people felt. I'm curious to know what you think. After you read the list of the world's best symphony orchestras, share your opinions or your ideal rankings.
