Scoring Documentary

Documentary music must sustain ten minutes and vanish the moment an interview begins.

Music supports, it does not lead

Documentary carries information first: interviews, voice-over, location sound. Music exists to make that information easier to take in, not to speak in its place. A simple test is to close the picture and listen: if the music takes attention, it is too full. A good documentary score is often hard to hum afterwards; what stays is the feeling of a particular moment.

Sustaining a long stretch

A single sequence can run ten minutes, and the music has to remain present without becoming repetitive. Use a small cell, a few notes, one timbre, a low pulse, and hold it through changes of orchestration and register rather than through continuous melodic development. Change the texture every two or three minutes so the ear has something new to hold, but do not change the theme. Generation tools are good at eight bars and poor at ten minutes, so long spans have to be assembled.

Period texture

A historical section is not solved by adding generic old music. Period comes from recording character, instrumentation and playing habits: narrower bandwidth, less low end, a little noise floor, uneven timing. Imitating those with synths takes restraint, because too much noise sounds like a broken radio. Real instruments with gentle band-limiting and distortion often convince more than pure synthesis. And do not let the whole film sit in the same retro wash, or it becomes a mannerism.

Yielding, and the limits

Pull the music down or stop it one or two seconds before an interview begins, bring it back after the sentence, and never return at the previous level in one jump. If the interview has background noise, music can fill the gaps but must not cover the consonants. When the subject changes, keep one musical thread instead of changing tracks with each face. The commonest failure is wall-to-wall music that tires the audience and leaves the real climax with nowhere to go; the next is music that concludes before the picture does, already weeping while the film is still stating facts. Clean the long fades and loop tails in generated material, or the music will still be fading out as the interview starts.
