Cover art for Departure lyrics by Moody Blues, The

To begin with, the lyrics posted here should read "To find THE LOST CHORD" at the end. Even if this song's lyrics arose from an acid trip, that only ever affects word choice, lol. The imagery is still reflective of HOPE: a deeply-rooted oak tree, a flower persisting to bloom through an airport tarmac, flying to the sun without burning/losing wings. Each of those imagery examples represent PERSISTENT HOPE. As in "hope springs anew" with the living things, and the naive hope even in the face of adversity as Icarus flies to the sun with man-made wings, all these images are ones of HOPE. However, the purpose of HOPE is to fulfill that need mentioned in the second line which is LOVE. Without HOPE, people don't struggle to find LOVE after that first bad break-up, but the "chord" (that's ironically "lost" from the entry) is "lost" unless it's vibrating inside. Metaphysical theory stipulates that people who feel as though they share "connections" actual share energy "chords" and we also use the image of chords to describe LOVE as in our heartstrings sing when we meet that person with whom we share a connection. Physical science also supports geological "attuned" spots that have predictable physical events that support the human chord theory. People need HOPE to find LOVE and eventually the LOST CHORD. For the more pessimistic, LOVE does not have to be romantic love. It could also apply to love of humanity or passion for something of substance in life.
