Selecting music requires more than finding a track that sounds appealing. Video editors need to consider tempo, instrumentation, mood, vocals, and the relationship between music and dialogue.
Whether you edit YouTube videos, promotional content, cinematic sequences, or social media reels, understanding these sound design techniques can help you make better audio decisions. If you're developing your editing skills, explore this guide to video editing skills, tools, and career opportunities to understand how audio editing fits into the wider post-production workflow.
This guide covers BPM, instrument selection, music discovery platforms, audio mixing, beat syncing, and transitions.
Start by identifying the emotion and pace of your footage. A fast-paced action sequence needs a different soundtrack from a slow interview or emotional documentary.
Consider three elements before selecting a track:
BPM (Beats Per Minute): Measures the tempo of a musical track and helps you understand its rhythm.
Instrumentation: Determines the texture and character of the soundtrack through instruments such as piano, drums, strings, and guitars.
Mood: Helps you select music that matches the atmosphere of a particular scene.
For example, an energetic product montage might work with electronic music and a faster tempo. A personal interview may need soft instrumental music that stays behind the speaker's voice.
Test different tracks against your footage. A song that sounds suitable on its own might not match the timing or emotional direction of your video.
The relationship between sound and visuals is also important when creating a montage. Learn more about how shot selection and sequencing build better stories, including how music and sound effects can support the narrative.
BPM stands for Beats Per Minute. It measures how many beats occur in one minute of music.
A 60 BPM track has one beat per second, while a 120 BPM track has two beats per second. Higher BPM tracks generally feel more energetic, although rhythm, instrumentation, and musical arrangement also influence how fast a track feels.
Here is how different tempos can fit video content:
High-BPM music: Suitable for action sequences, energetic montages, sports videos, and quick visual transitions.
Low-BPM music: Works well with interviews, emotional storytelling, slow-motion footage, and cinematic scenes.
Suppose your video contains fast narration and frequent visual changes. A track around 100 BPM could be a useful starting point. Test it against the actual footage before making a final selection.
Many music libraries include BPM filters. These allow editors to narrow their search by tempo instead of listening to every available track.

Testing music against footage is easier when you keep your music library and editing software open side by side.
This split-screen workflow lets you preview a track while watching the video it needs to accompany.
Follow these steps:
Open your preferred music library in one window.
Open your video editing software in another.
Play a candidate track alongside the footage.
Check whether its tempo matches the visual pacing.
Listen for conflicts with dialogue and narration.
Save tracks that fit the scene and compare them before making a final choice.
A track may sound good through headphones but feel distracting when played with narration. Testing it directly against the video helps you identify these problems before downloading multiple alternatives.
For beginners, understanding the complete editing process can make this workflow easier. This step-by-step roadmap to learning video editing covers the progression from basic editing and audio synchronisation to more advanced techniques.
Musical instruments influence the mood and energy of a soundtrack. Their sound characteristics can change how viewers interpret the same visual sequence.
The following table explains where commonly used instruments can fit:
|
Instrument |
Suitable video scenes |
|
Violin |
Suspense, mystery, and emotional sequences |
|
Drums |
Action, energetic montages, and fast-paced content |
|
Electric guitar |
Rock-themed videos and intense sequences |
|
Piano |
Interviews, emotional storytelling, and cinematic scenes |
|
Strings |
Dramatic sequences and orchestral compositions |
When editing interviews, tutorials, or voiceovers, choose music that leaves enough space for the speaker.
Heavy bass, prominent percussion, and distorted electric guitars can compete with speech, especially when their frequencies overlap with the voice.
Softer piano arrangements, ambient textures, and restrained percussion are often easier to mix behind narration.
You can also adjust the music volume or use equalisation to reduce frequencies that interfere with speech clarity.
Audio editing is an important part of a video editor's skill set. This guide to video editing skills and tools also explores audio mixing, sound effects, and other techniques that contribute to a polished final video.
Background music helps establish the atmosphere of a scene. A soundtrack can make footage feel tense, cheerful, reflective, or energetic without changing the visuals.
Consider these examples:
Serious or mysterious scenes: Explore dark ambient music, low drones, and suspenseful orchestral arrangements.
Entertainment videos: Try upbeat electronic music, funk, or cheerful instrumental tracks.
Emotional storytelling: Consider soft piano compositions and restrained strings.
Inspirational videos: Look for uplifting melodies and gradual musical builds.
Imagine editing a video about a student's academic journey. Soft piano music might suit the opening, while a gradual orchestral build could accompany the student's achievements.
Use mood filters on music platforms to discover tracks that fit the emotional direction of each scene.
The choice between instrumental and vocal music depends on the content and whether the video includes spoken dialogue.
Tracks with vocals can work well when the visuals carry most of the storytelling and there is little or no spoken dialogue.
Common examples include:
Cinematic montages.
Motivational videos.
Achievement and success stories.
Transformation videos.
Travel and lifestyle sequences.
Lyrics can add another layer of meaning when their message matches the visuals. However, they can distract viewers when the video contains narration.
Instrumental tracks are often suitable for tutorials, interviews, educational videos, and documentary-style content.
Without lyrics competing for attention, viewers can focus more easily on the speaker.
Instrumental music also gives editors more flexibility when adjusting audio levels beneath dialogue.
These are practical guidelines, not fixed rules. Vocal music can work behind narration if the arrangement is subtle and the lyrics do not interfere with the spoken content.
Music discovery platforms give video editors access to different genres, instruments, moods, and audio assets.
Three platforms worth exploring are:
ElevenLabs: Provides AI-powered audio tools, including music-generation capabilities.
Pixabay: Offers music and sound effects across different genres and categories. Check individual licensing conditions before publishing.
Envato: Provides music tracks, sound effects, and other creative assets for video production.
Depending on the platform, editors can explore:
Tracks categorised by mood and genre.
Music based on tempo and BPM.
Instrumental compositions.
Similar tracks with comparable musical styles.
Sound effects for transitions and scene changes.
Some services also provide music-generation or audio-customisation features.
Before using any track, read its licensing terms. Check whether commercial use is permitted, whether attribution is required, and whether the licence covers your intended distribution channels.
A free download does not automatically grant unrestricted copyright usage.
Selecting suitable music does not guarantee a good audio mix. You also need to control its volume in relation to dialogue, sound effects, and other audio elements.
If the music is too loud, viewers may struggle to understand the speaker. If it is too quiet, it may become difficult to hear.
You can use the following approximate levels as an initial mixing reference:
|
Audio element |
Suggested starting level |
|
Voice or narration |
Around -12 to -6 dBFS peak |
|
Background music |
Often around -25 to -18 dBFS peak |
|
Heavy or dense music |
Adjust lower if it competes with dialogue |
These figures are starting points, not fixed mixing standards. The actual levels depend on the source recording, musical arrangement, loudness, and final output.
Use these techniques while mixing:
Set the dialogue level first.
Lower the music until every spoken word is clear.
Use volume automation when dialogue intensity changes.
Apply equalisation if the music competes with the voice.
Listen to the final mix through headphones and speakers.
For a more consistent result, check the final integrated loudness and true peak against the delivery requirements of your publishing platform.
These audio decisions are especially important for short-form content, where viewers often expect clear narration and engaging sound. Explore social media video editing techniques for Reels and Shorts for more insights into balancing voiceovers, music, and sound effects.
Playing music continuously can make a video sound repetitive. Some scenes work better without a soundtrack.
Silence can direct attention towards dialogue, natural sounds, or an important visual moment.
For example, imagine an interview where a student describes a difficult personal experience. Reducing or removing the background music during that statement can make the speaker's voice easier to follow.
You can bring the music back when the scene changes or the narration moves towards a different topic.
Avoid cutting a music track randomly. Find a suitable point in its arrangement where the melody or rhythm allows a natural ending.
You can also use:
Fade-out: Gradually reduces the music volume.
Volume automation: Gives you control over exactly when the music becomes quieter.
Audio crossfade: Overlaps two audio clips to create a smoother transition.
Musical resolution: Ends the track around a point where the composition feels complete.
These techniques help prevent abrupt changes in the soundtrack.
When a video moves between scenes, the soundtrack may need to change as well. Switching between unrelated tracks without planning can make the audio feel disconnected.
Use the following techniques to maintain continuity.
When moving from one music track to another, compare their tempo, rhythm, instrumentation, and mood.
For example, two cinematic tracks with similar orchestral arrangements may transition more naturally than a sudden switch from ambient piano to heavy electronic music.
You can also use music discovery tools to find tracks with similar characteristics.
For more practical guidance, read about video editing transitions, including cuts, fades, and scene changes. The guide also explains how music and rhythm can influence the timing of visual transitions.
A riser is a sound effect that gradually builds in intensity or pitch. Editors often use it before a transition, reveal, or major visual moment.
A simple workflow involves:
Gradually reducing the volume of the first music track.
Placing a riser sound effect before the scene change.
Aligning the end of the riser with the visual transition.
Starting the next track at an appropriate musical point.
This approach works well in promotional videos, trailers, and cinematic edits.
Beat syncing involves aligning selected visual cuts, transitions, or actions with the rhythm of the background music.
It is commonly used in promotional videos, montages, music videos, and social media edits.
Try these techniques:
Start a new visual section on a strong musical beat.
Align selected B-roll shots with changes in rhythm.
Place important transitions on suitable beats.
Remove unnecessary musical introductions when the video needs to start immediately.
You do not need to place every cut on a beat. Allow some shots to run across multiple beats so the edit does not feel mechanical.
A low-pass filter reduces high-frequency sounds while allowing lower frequencies to pass through.
In video editing, this filter can make background music sound distant, muffled, or as though it is playing behind a wall.
For example, you can apply a low-pass filter when a scene shifts from a character's normal surroundings to an imagined memory or distant sound perspective.
To use it effectively:
Select the music clip in your editing software.
Add a low-pass filter from the audio effects panel.
Adjust the cutoff frequency to control how much high-frequency content remains.
Automate the filter if the scene requires a gradual change.
Compare the processed audio with the original track.
Avoid applying aggressive filtering throughout the entire video. Use it when the scene requires a change in sound perspective.
Choosing background music requires you to evaluate how a track works with the footage, narration, and pacing.
Keep these practices in mind while editing:
Match the music's mood with the emotion of the scene.
Use BPM as a reference when evaluating tempo.
Select instruments that suit the type of footage.
Choose instrumental or vocal tracks according to the content.
Keep dialogue clear through careful volume balancing.
Use silence when a scene needs greater focus.
Apply fades and crossfades for smoother audio transitions.
Align selected visual cuts with musical beats.
Experiment with low-pass filters when a scene requires a distant sound effect.
Check music licensing before publishing the video.
