I noticed a small thing in "House of Four Doors (Part 1)" when I listened to
In Search of the Lost Chord yester-day. In the line "We'd lost our way," "way" is sung with an ascending melisma in one voice (C D) and a descending melisma in an-other (G F#). Musically, "way" is being pulled in two different directions, and this illustrates the confusion of being "lost" and not knowing whether to go up or down.
