Good background music starts with the video, not a genre menu. Mark where the viewer needs to listen closely, where the picture needs momentum, and where a change should feel important. Then make an instrumental with enough movement to carry those moments and enough empty space to stay behind the voice. Generate the music before the final mix, but after you know the rough shape of the edit.
Start with a simple cue sheet
Watch the rough cut once without music and write down the job of each section. You do not need frame-accurate notes. A short list with timestamps is enough to stop one track from flattening the whole video into the same mood.
- Cold open: decide whether the first line needs silence, a single texture, or an immediate pulse.
- Main explanation: use the least busy part of the music so names, numbers, and instructions remain clear.
- Demonstration or montage: allow a stronger rhythm or a wider arrangement when the picture is doing more of the talking.
- Reveal or key point: plan a lift, pause, or clean musical change instead of turning the whole track up.
- Ending: leave enough of a final phrase to resolve naturally under the last sentence or end screen.
Give the music one job at a time
Background music can keep a tutorial moving, soften a quiet talking-head section, build anticipation, connect a montage, or make an ending feel complete. Pick the main job for each cue. A track asked to be calm under detailed speech and dramatic under a fast reveal at the same time will usually do neither well. Use a second cue, or plan a clear change in the arrangement, when the job changes.
Write a prompt that leaves room for narration
Describe the role before the style. A useful prompt names the video type, pace, leading instruments, density, and energy curve. It also says what should stay out. Avoid vocals, dominant lead melodies, abrupt drops, and constant fills when someone will be speaking over the track.
- Tutorial: Instrumental background bed for a calm eight-minute tutorial, steady mid-tempo pulse, warm muted guitar, soft bass and dry percussion, sparse arrangement under speech, a small lift for the demonstration, no vocals and no solo lead.
- Product walkthrough: Clean electronic instrumental for a focused software demo, light ticking rhythm, rounded synth bass and short keyboard accents, restrained during instructions, slightly wider at the feature reveal, no dramatic drop.
- Travel montage: Bright instrumental for a city-day montage, crisp percussion, light guitar and airy keys, forward motion without a crowded melody, brief breakdown before the final wide shot, no vocals.
Treat these as starting points. Replace the video type, emotional direction, and instruments with choices that fit your footage. If the first result feels crowded, ask for fewer instruments and a sparser lead before changing the entire genre.
Create two controlled versions
Open the AI Music Generator in Prompt mode, switch on Instrumental, and paste the sound direction. For the second version, change only one useful variable: the density, the leading instrument, or the size of the final lift. Listen under a short piece of real narration, not by itself. Keep the version that makes the words easiest to follow. A track that sounds less impressive alone can be the better background cue.
Cut the track to the picture
- Put narration and music on separate tracks in your editor so every change remains reversible.
- Trim on a musical phrase or clean beat. Add short fades to hide clicks and make an early ending feel intentional.
- Loop a stable middle section rather than the intro; introductions often contain changes that become obvious when repeated.
- Lower or remove music before a dense explanation, important quote, or emotionally exposed line.
- Bring a new layer in at a scene change instead of using a louder level as the only way to create energy.
Mix for clear words, not a magic number
There is no universal background-music level. A quiet acoustic cue and a dense electronic cue can read very differently at the same meter value. Set the narration first. Bring the music up from silence until it adds motion, then pull it back slightly. If a viewer has to work to understand a word, the music is too loud, too busy, or occupying too much of the same range as the voice.
- Automate the music lower under detailed sentences instead of forcing one level across the entire video.
- Use ducking gently if your editor supports it, then listen for distracting volume pumping at the start and end of phrases.
- If lowering the cue makes it disappear, choose a simpler arrangement rather than pushing the same crowded track back up.
- Check once on headphones and once through a phone or laptop speaker at a low listening level.
- Watch a full minute without touching the controls. Constant adjustment is a sign that the cue or arrangement needs another pass.
Check usage rights before publishing
Creative fit and permission are separate checks. Confirm the current license or permission for the exact audio file and the way you plan to use it, especially for monetized, sponsored, or client work. A filename or description that says free is not proof of permission. Keep a copy of the applicable terms or receipt with the project. This guide covers the creative and editing workflow; it does not grant rights to any recording.
Run a final 60-second review
- Every spoken sentence remains understandable at a low playback level.
- The music has a clear job in each section and stops when silence works better.
- No vocal, solo, fill, or transition steals attention from the picture or narration.
- Loops, cuts, and fades sound intentional rather than repeated or abrupt.
- The ending lands cleanly under the final line or end screen.
- The project includes a record of the music's current usage terms.
