The octave is the most basic interval—same note, higher pitch. But it represents unity and completion. Think of the dun-dun-dun in a video game level-up sound. That’s an octave. It’s the sound of “you win.” And in business, “you win” means “renew your subscription.”

Monetize it: design a notification sound for a budgeting app. Use a clean octave interval. It subconsciously makes users feel like they’ve achieved financial stability—even if they just spent rent money on sneakers. The app retains users. You get a royalty. Cha-ching is an octave, by the way.
The Final, Slightly Ironic Note
Look, I’m not saying you should compose a symphony for a cryptocurrency scam. But every interval is a psychological lever. You can pull them to make people laugh, cry, or buy a $9 avocado toast. The trick is to listen to your own gut reaction first. If a minor seventh makes you feel nostalgic for a breakup you never had, that’s a market.
So go ahead. Open your DAW, or just hum into your phone. Find the interval that makes your back hair stand up. Then ask yourself: “Can I sell this feeling?” The answer is almost always yes. Just remember: you are now one of the manipulators. Use your power wisely. Or don’t. But charge a premium for it.
Now go make that tritone pay rent. I’ll be over here, writing a jingle for a funeral home using only major sixths. (It’s called “Positive Closure.” The client loved it.)
