Why Great Films Need More Than a Sad Piano Prompt

There’s a big difference between music that fills space and music that actually tells a story.

As generative technology becomes more accessible, it’s easy to think a ‘sad piano’ prompt is a shortcut to a finished soundtrack. The reality is, while these tools are evolving, there’s still a clear gap between AI film scoring and the work of a human composer.

The formula of the background track

Most stock or corporate music follows a fairly predictable formula: a set number of chords, familiar instrumentation, and a steady, upbeat feel. Because these tracks follow a simple, predictable structure, they’re ideal for AI to replicate.

AI doesn’t need to understand a brand to generate a guitar-driven track that sits neatly in the background of a presentation.

If the goal is simply to add a bit of ‘decor’ to a video, a generated loop might seem like a quick fix.

But for professional projects, that convenience can come with hidden trade-offs. Questions over how the data is sourced, along with the lack of clear legal protection, mean these tracks don’t offer the same assurance as human-created music.

Film and high-end video production need more than a quick fix.

The narrative gap

Where this approach starts to struggle is with storytelling.

Film isn’t formulaic. A scene can shift in a moment — a realisation, a change in mood, a sudden lift in tension. The music needs to move with it.

That’s not something AI really understands.

It can’t watch a scene and recognise when silence would be more powerful than music. It doesn’t know when to hold back or when to push forward. It’s not reacting to a story; it’s simply filling time.

Think of a moment just before a key reveal, where pulling the music out completely creates tension; that kind of decision isn’t something an AI prompt can anticipate.

Consistency vs disconnected clips

One of the biggest giveaways with AI-generated soundtracks is how disconnected they can feel.

Because it’s not really seeing the film as a whole, the music often comes across like a series of loosely joined sections. Transitions feel off, key moments don’t quite land, and there’s usually very little in terms of sound design.

A human-led approach is different. It’s not just about laying music over a video; it’s about shaping it around the edit, hitting key moments, and using subtle sound design to tie everything together so it feels like one continuous piece, not separate parts.

Finding the emotion in the edit

A computer can generate endless notes, but it cannot create a moment.

As AI film scoring becomes more common, it still struggles to capture the deliberate choices a composer makes.

What human-composed music does well is interpret emotion and bring something extra to the visuals. It adds intent.

With AI filling the space with more background music, that difference becomes more noticeable. For projects with a clear vision, the soundtrack shouldn’t feel like an afterthought or a quick fix; it should feel like part of the story. And that’s not something you get from a prompt alone.
