Starting immediately after the cacophony that ends "21st Century Schizoid Man", the mood of this song is a stark contrast; it is serene, simple and peaceful. Ian McDonald's flute begins the song, and is one of the lead instruments throughout. He also plays a classical-inspired solo in the middle of the song as a "C" section and a longer one at the end as a coda.
These themes would be revisited by the band, notably on their second album, In the Wake of Poseidon. "Pictures of a City", with a similar mood as "21st Century Schizoid Man", would be followed by "Cadence And Cascade", another calm song.
This song is the only song on In the Court of the Crimson King that does not have at least one separately titled section.
An earlier demo version of this song may be found on the now out-of-print LP ''Young Person's Guide to King Crimson'', which featured Robert Fripp (guitar), Peter Giles (bass), Michael Giles (drums), and Ian McDonald (flute), along with Judy Dyble (formerly of Fairport Convention and McDonald's girlfriend at the time) on vocals. This version was more up-tempo and lighter in instrumentation. The ''Young Person's Guide recording and another demo of the same song were recorded in 1968 by Giles, Giles and Fripp. However the song did not actually appear on a Giles, Giles and Fripp record until The Brondesbury Tapes'' was released on CD in 2002.
