A jingle, or a sonic logo, is two to four seconds of audio that has to remain tolerable after someone has heard it a thousand times. That constraint makes it much harder than it looks, and it is a different problem from generating a track: you are not looking for something good, you are looking for something that does not become irritating.
Generation is a reasonable way to explore directions cheaply. The judgement about which one survives repetition is yours.
TL;DR
- Two to four seconds. Longer is not a jingle, it is a bed
- Cheapest exploration on 8frame: MiniMax Music v2 at 5 credits, so thirty directions cost 150 credits
- Short is harder than long for these models, because there is no room to develop
- The repetition test: play the candidate fifty times in a row. Most fail
- Trademark matters. A sonic mark can be registrable, and generated audio raises questions about ownership worth asking before you commit
Why short is hard for a model
Generative music models build texture over time. Ask for three seconds and there is no room for the arrangement to establish itself, so output tends to be either a fragment that sounds truncated or a loop that sounds like a loop.
The practical workaround: generate longer and cut. Ask for 20 to 30 seconds in the style you want, then find the two-second phrase inside it that works. A generated 30-second piece often contains one genuinely good figure, and extracting it is easier than asking for it directly.
What it costs
Canon 8frame prices, a credit is $0.01 at pack rate:
| Route | Credits |
|---|---|
| MiniMax Music v2 | 5 per generation |
| Lyria 2 | 13 per 30 seconds |
| MiniMax Music 3 | 17 per generation |
| ElevenLabs Music | 81 per minute |
| ElevenLabs SFX | 5 per effect |
| ElevenLabs TTS, spoken tagline | 13 per 1,000 characters |
Thirty directions on MiniMax Music v2: 150 credits, about $1.50. That is the right way to spend here, because you are looking for one survivor out of many rather than perfecting a single attempt.
The repetition test
This is the only evaluation that matters and almost nobody does it.
Take your three best candidates and play each one fifty times in a row. Not five. Fifty.
What fails: anything with a prominent high-frequency element, anything with an unusual interval that is charming once and grating at twenty, anything too melodically busy, anything that resolves in a way that feels unfinished.
What survives: simple intervals, a small number of notes, warm timbres, and something that resolves cleanly so the ear is not left waiting.
Your audience will hear it far more than fifty times. If it irritates you at fifty, it is not the one.
What makes a sonic logo work
Three to five notes maximum. The most recognisable sonic logos in the world are very short melodic figures.
One timbre, or two. Complexity does not survive compression, phone speakers, or repetition.
A clean resolution. It should feel finished, not cut off.
Distinctiveness without novelty. It needs to be yours without being odd, which is the hard part.
Works at bad quality. Test it on a phone speaker, quietly, in a noisy room. That is where it will actually be heard.
The trademark question
Sonic marks can be registered as trademarks in many jurisdictions, and if your jingle is going to be a real brand asset, the question of whether you own it matters.
Two things worth asking a lawyer rather than a blog:
- Whether generated audio carries the protection you need for a registrable mark. Protection for AI-generated work is unsettled in several jurisdictions.
- Whether the output is distinctive enough and does not resemble an existing registered mark.
For a small business using a jingle informally, this is likely not worth the legal spend. For anything that will become a brand asset you would defend, ask before you commit, not after.
Where generation fits honestly
Exploration. Thirty directions for $1.50 is a genuinely good way to find out what your brand should sound like.
Small business use. A jingle for a local business, a podcast sting, a channel sound. Generation is entirely adequate.
Briefing a composer. Take your favourite generated direction to a person and have them make the real thing. This is a legitimate and efficient use, and the composer will do a better job with a reference than with a description.
FAQ
How long should a jingle be? Two to four seconds. Three to five notes.
Can I trademark an AI-generated jingle? Registrability of sonic marks exists; whether generated audio meets the requirements is jurisdiction-dependent and unsettled. Ask a lawyer if it matters.
What is the cheapest way to explore? MiniMax Music v2 at 5 credits, thirty directions for $1.50.
Why does my short generation sound truncated? Because models need room to develop. Generate 30 seconds and cut the good two seconds out of it.
Generate thirty, play the best one fifty times. The 8frame canvas is free and unlimited, and generation is paid from $19/month.
