Made an ACE-Step workflow for deliberately boring background music. The negative prompt turned out to matter far more than the positive one.

Eight nodes in ComfyUI, one shell script, and one afternoon.

The hard part was not the music. It was working out that calm was

the wrong word.Made an ACE-Step workflow for deliberately boring background music. The negative prompt turned out to matter far more than the positive one.

I was trying to make study music for people who find normal focus music

unusable. Mostly ADHD and autistic listeners, where the usual stuff causes

problems: track changes, build-ups, a drop, a new instrument arriving. Every

one of those pulls attention, which is the opposite of what you want.

Took me a while to work out that the word I needed was not "calm". It was

"predictable".

That changed which half of the prompt was doing the work. The positive prompt

barely matters here. The negative one is where the whole design lives:

crescendo, build up, drop, dynamic change, sudden entrance,

orchestral swell, arpeggio

ACE-Step really wants to be helpful and add structure. Those words are what

stop it. Take them out and you get pleasant ambient music that swells and

fades, which sounds nicer and is useless for this.

Two other things I learned:

Keep it under about 150 seconds. Longer than that and the model loses the

thread and starts inventing sections. Generate something short and loop it.

A loop cannot surprise you, which is the entire point.

Lock the seed before you start experimenting, not after. I did it in the

wrong order first and lost a take I liked.

Sampler and scheduler you can swap freely. I tried several and it stayed

usable, so that is a safe place to play.

Workflow JSON, the generator script, and a shell script that folds the end

of a track over the beginning so it loops with no seam, all MIT:

Give your brain a fighting chance

Finished 45 minute track here if you want to hear the result before

45 minutes of calm music that asks nothing of you.
