For those that know my love for stats in sports, you would think there may be stats for music too, Right? Indeed there are, according to "Bachtrack". If you have ever been to a symphony concert or an opera, have you ever made these observations? 1) That's a young looking conductor 2) How many times have they played works by _ composer this year? 3) Why did they program this composer?
To answer a few of these questions, I have provided a link below that sheds light on these observations. Just a side note, Beethoven's popularity did not surprise me at all. Enjoy!
