It may come as a surprise but Gustav Holst’s orchestral suite The Planets is not about the actual planets in our solar system – rather, he has composed music that takes on the personality of the planets in an astrological sense. One point of inspiration was a book that was divided into chapters titled after the planets, and described each of their astrological characteristics. The Planets suite by Gustav Holst: our Evening Masterwork tonight at 7 on Classical WSMR 89.1 and 103.9.
