Recommended Free Tools
AIVA is the strongest starting point for trailer music when you need editable instrumental ideas rather than a finished vocal song. It generates in more than 250 styles, accepts audio or MIDI influences, and lets you edit generated tracks. Its free plan is non-commercial and allows three downloads per month, so a released trailer requires a paid plan with the rights that match your use.
What Trailer Music Needs
A trailer cue usually has to establish a mood quickly, build toward a reveal, and leave space for dialogue, sound effects, or title cards. Look for control over style, length, arrangement, and downloadable formats. The entries below do not establish that any service has a dedicated “trailer” genre or automatic picture-lock scoring, so confirm those details with each vendor before committing.

Best AI Music Generators For Trailers In 2026
1. AIVA — Best For Editable Instrumental Cues
AIVA pairs broad style generation with influence uploads and track editing. You can provide an audio or MIDI influence, generate across more than 250 styles, and revise the resulting track. That combination suits a trailer workflow where a short motif needs several passes before the final edit.
- Free: non-commercial, three downloads per month, and tracks up to three minutes.
- Standard Annually: paid plans start at €11 per month when billed annually; paid plans add monetization rights, while WAV export is available on Pro.
- Constraint: vocal generation is unavailable. Standard monetization is limited to specified social platforms, so check whether your trailer distribution is covered.
2. SOUNDRAW — Best For Video-Oriented Instrumental Control
SOUNDRAW generates instrumentals by genre, mood, theme, instruments, tempo, and length. Its preview-with-video workflow and controls for instruments or track elements are directly relevant when you are shaping a cue around trailer pacing. It does not offer vocal generation or audio upload.

Trailer Prompt And Editing Workflow
- Describe the trailer’s emotional arc, instrumentation, tempo, and intended length. Ask for an instrumental cue when dialogue needs space.
- Generate several short ideas, then keep the motif whose opening establishes the premise quickly.
- Use influence audio or MIDI where supported, or use the service’s editing, extension, remix, or section tools to shape the rise and final hit.
- Export the format and stems your edit requires, and verify the plan’s commercial rights before publishing.
Rights And Voice Checks Before Release
Consent matters whenever you upload reference audio, use voice references, or add recorded vocals: only submit material you are allowed to use, and follow each platform’s terms. AIVA has no vocal generation; SOUNDRAW does not offer vocal generation or audio upload; Mubert does not offer audio upload. Suno, Udio, and Loudly provide vocal-related features, so review their current consent and licensing terms before releasing a trailer.
