5.11 What is the meaning behind the song, "House of Four Doors?"
The four doors are supposed to conceal four different musical ages:
Door 1: medieval (folk/flute)
Door 2: baroque/classical (harpsichord)
Door 3: romantic (some fans hear this section as a variation
of Tchaikovsky's piano concerto no. 1 (`a la "House of Four Doors"), while
others hear Gershwin's "Rhapsody in Blue")
Door 4: modern era (a rock band playing "Legend of a Mind")
