I don’t think I have told you about my trip to Tanglewood’s music festival.(20)When I was in college, I won a music competition and the prize was a week at Tanglewood. Anyway it is one of the world’s most famous music festivals and the summer home of the Boston Symphony Orchestra. It is located in the beautiful Berkshire Hills in New England. The summer musical season consists of about fifty concerts given over about nine weeks: from July 1st through the first week in September. The biggest stars on the music scene appear here. The year I went I was lucky enough to see Leonard Bernstein conducting. I understand it is sometimes hard to get tickets but of course mine were a part of the prize. If you want to sit inside, the tickets are expensive.(21)It’s much cheaper to sit outside on the lawn. But it might rain, or some nights are really cool even in the summer. Either way the sound system is excellent. So it doesn’t really matter where you sit.(22)I seem to recall that the festival got started in the 1930s. Some Berkshire residents invited a symphony orchestra to perform a few outdoor concerts. The concerts were so successful that after a couple of years somebody donated a family estate as a permanent home. After that things really took off. And the festival has gotten bigger and better every year. Attending was such a wonderful experience. I’d love to be able to go again. And I hope that all of you would be able to go too.
