"do everything" with the S770 sampler, and did not have a hard disk editor available, it was a "made even slower." In order to hear whether something worked or not, he had had to load it into the S770 sampler, copy it onto tape, "maybe do this for five or six tracks more" and then create the rough DAT mix to listen to the result. As a result, it would take them half a day to be able to listen to something, whereas the same edit would have taken two minutes in a 24-track Fairlight. Brook noted, commenting on the overall sessions, that he "cannot imagine a more laborious way of making a record." Sound on Sound considered the sessions a "technological nightmare". However, on one occasion during recording, after a particularly long period of "laborious editing, sampling, and shifting things around in MIDI sequences", several musicians from Baba Maal’s band arrived at the studio to record some overdubs for them. Brook said that "it was amazing how that instantly lifted our spirits. When you get so bogged down in the details, you quickly lose the mood."

The genre features dreamy, atmospheric keyboards and guitars, simple, mid-tempo rhythms, and a kind of low-key understatement.” Consumable Online said that "the mood of Night Song swings rapidly from track to track." They also drew "certain parallels" between the album and many of ambient pioneer Brian Eno’s works and productions, noting that Brook has done extensive work with Eno in the past. They also noted that parallels could be drawn with the music of Brook's 4AD labelmates Lisa Gerrard and Dead Can Dance, who they noted also sometimes "fuse traditional foreign (or pseudo-foreign) vocals and rhythm with modern ambient music and, on occasion, technological sound," saying that this makes traditional music somewhat more accessible to the listener while adding diversity to the elements of ambient.
