Why music matters
Music is the most emotional layer of your film. Learn why it hits so hard, and how to use that.
The Film Score Blueprint
Think in layers: drones, textures, melodies, hits and risers, and how to stack them into a score.
Enhancing licensed music
Find a song’s key and build intros, outros and transitions that feel custom.
Composing from scratch
Build an original score for a scene using nothing but the collection.
Filmmakers don’t go back.
“My licensed music is the background now. This pack is the foreground.”
“It’s in key, so I can mold any song into what I need it to be for my videos.”
“These sound like songs, and you get all the tools to build them.”
“It should be industry standard in wedding films. It just gives the editor that much more control.”
“We’re not beholden to the structure of a song anymore. We can actually think like storytellers.”
“Literally a drag-and-drop solution to make your films as good as they can possibly be.”
“I’ve never had so many compliments on my films sounding like a real Hollywood movie.”
“I was skeptical it could beat Volume 1. Oh my gosh, it is so much better.”
“The number one thing that has leveled up my films. More than color grading. More than anything.”
“It’s completely revolutionized the way I edit.”
“Okay, I get it now. I have no words.”
“Something I didn’t even know I needed. It’s going to completely change how you make your films.”
Songs are necessary.
They’re just not always necessary.
Songs follow someone else’s timeline.
A licensed track builds, drops and ends when the musician decided. Your story doesn’t work that way.
Tonal sound effects fill the space around it.
The build before the drop. The quiet moment where a song is too much but silence isn’t enough. The bridge between scenes.
Match your key. That’s it.
Every sound ships in all 12 keys, labeled Major, Minor or Universal. Find your song’s key, grab the matching folder, and layer.
Follow along to see what happens.
New sounds, behind-the-scenes, tutorials and the occasional vlog. We’re building this business right in front of you.

Follow @multiply.sound →Questions, answered.
Do I need to know music theory?
Not at all. Every sound is labeled by key. Match your song’s key, avoid pairing a Major-only sound with a Minor-only sound, and you’re scoring. If you can drag clips into a timeline, you can use this.
What editing software does it work with?
Anything that accepts WAV files: Final Cut Pro, Premiere Pro, DaVinci Resolve, After Effects, CapCut Desktop. No plugins, no DAW.
How do I find the key of my song?
Many licensing sites list it. If not, apps like Auto-Key or Tunebat will tell you in seconds. The courses walk you through it.
Can I use these in client and YouTube work?
Yes. Royalty-free for client work, YouTube, social, commercial and paid projects, with a lifetime license.
Which collection should I start with?
Modern, synth-driven content: Vol 3. Organic and emotional films: Ambient Cinematic. Maximum variety with drums: Vol 2. Want everything? The Master Bundle.
Your story deserves its own score.
Stop bending your edit around someone else’s song. Take control of the emotion in every scene.
