Would it be fair to say that the greatness of a composer is measured by the sum of his influences and the number of performances of his work? In almost all major markets you have a Bach's Lunch (one hour of Bach every day) and Mostly Mozart Festival. Tchaikovsky's Nutcracker is performed year after year in every town at Christmas like clockwork, and you can bet in any given week, some orchestra somewhere is performing his Piano Concerto No. 1, Pathetique Symphony, Violin Concerto, or Swan Lake and Sleeping Beauty suites. I'm also willing to bet that, on any given day of the year, someone somewhere is playing something by Chopin or Beethoven, whether it's at a competition, church or Town Hall recital, professional recording or concert.
