Royalty-free music generator rights guide
Video game music generator for menus, levels and boss fights
SoundUser is a video game music generator for indie developers, jam teams and modders who need finished AI game music from a text prompt or lyrics. Pick a scene, set tempo and instruments, then generate a track. A track costs 10 credits and runs up to 180 seconds.

Match the scene before you write the prompt
Game music works best when the prompt starts with the job: menu, town, combat, boss, stinger or credits. A main menu theme needs a hook at 80-100 BPM. Exploration can sit at 70-100 BPM with fewer drums. Combat usually needs 130-170 BPM and a clear pulse.
| Scene | Style | BPM | Instruments | Loop tip |
|---|---|---|---|---|
| Main menu | melodic synth, piano, light strings | 80-100 | piano, pads, plucked synth | keep the hook simple |
| Town or safe room | folk, ambient, soft JRPG | 70-100 | lute, flute, marimba, pads | avoid big fills at the end |
| Combat | electronic, metal hybrid, orchestral action | 130-170 | drums, bass, ostinato strings, synth bass | cut on a downbeat |
| Boss | orchestral choir or heavy bass | 140-170 | low brass, taiko, choir hits, distorted bass | make a calmer intro variant |
| Victory or defeat | short stinger feel | any | brass, chimes, snare, synth hit | export separate cues |
For non-vocal background cues, start with instrumental track prompts before adding genre color.
How to make AI game music in 3 steps
Make one cue at a time, not a whole soundtrack in one prompt. The generator needs a clear scene and a narrow musical target.
- Choose the scene and function: menu loop, overworld, stealth room, combat, boss, credits or trailer cue.
- Write a prompt with style, BPM, key, mood, instruments and the word
instrumentalif you do not want vocals. - Generate the track, then make a second version with the same BPM and key for calm, tense or battle states.
Keep names practical. forest_town_G_major_82bpm tells your editor more than beautiful village theme. If you are also cutting a trailer, compare the cue against music for YouTube videos because trailer pacing often needs stronger impacts than a gameplay loop.
Prompt details that stop game cues from drifting
A good game soundtrack generator prompt should lock tempo, key and arrangement before it describes mood. Vague prompts like epic fantasy game music often produce a cue with too many sections, vocal textures or a huge ending that fights the loop.
Worked example:
16-bit JRPG overworld theme, 132 BPM, C major, adventurous but not dark, square wave lead, pulse bass, triangle arpeggios, noise hats, simple A section, loopable feel, instrumental
This is meant to produce a bright overworld cue with a lead melody and steady chiptune rhythm. If it comes out too busy, remove one lead instrument and add sparse drums. If it feels too modern, add dry chipsynth, no cinematic drums. For neon levels, use synthwave game music language like arpeggiated bass, gated snare and minor key lead. For arcade shooters, electronic music prompts give you tighter drum and bass words.
Loops need editing, not wishful wording
SoundUser tracks have natural endings, so make the game loop in an audio editor by crossfading the tail into the head at a bar boundary. Put the grid on the prompt BPM, find a clean downbeat, then cut the first full bar that feels stable.
Do not fade everything. A hard drum transient can loop cleanly if the downbeat matches. Pads and reverb tails usually need a short crossfade. If the ending has a big cymbal swell or final chord, regenerate with no final hit or steady groove to the end. For retro cues, keep the delay and reverb light. Heavy ambience hides the bar line and makes loop edits messy.
Build calm, tense and battle versions in the same key
Variants swap cleanly when the BPM, key and main motif stay the same. Generate a calm town cue at 86 BPM in G major, then reuse the same prompt with tense low strings or soft combat percussion instead of changing the whole genre.
This matters for games that move between safe and danger states. A stealth room can use the same bass note and pad bed, then add shaker, low toms or filtered synth when an enemy appears. If you need heavier guitars for a boss or chase, borrow terms from metal arrangement prompts, but keep the original key unless you want a hard scene cut.
Chiptune, synthwave and fantasy scores all need different limits
Retro music works when the instrument list is small. For a chiptune generator AI prompt, use 120-160 BPM, square wave lead, pulse bass, triangle arpeggios and noise hats. Avoid asking for orchestral strings in the same prompt unless you want a modern hybrid.
Synthwave action likes 110-140 BPM, minor keys, arpeggiated bass, gated snare and wide pads. A 16-bit JRPG town cue usually sits lower, 70-100 BPM, with flute, bell, harp or simple chipsynth leads. For anime-style menu or battle cues, anime music prompts can help with bright hooks and fast string movement. Pick one lane per cue. Mixed style prompts are useful later, after the main theme is stable.
Rights records and production limits for shipped games
For a shipped game, keep your prompts, generation dates, project notes and export filenames in the same folder as your build assets. Storefront and platform rules still apply, and you may need your own review process before release.
Tracks you create are yours to use in your own projects, including commercial ones, under the SoundUser Terms
SoundUser is useful for placeholder music, jam builds, mods, trailers and many finished indie cues. It will not replace adaptive audio middleware for branching stems, live parameter changes or complex combat layering. It also will not replace a composer on a large title that needs a long thematic score, custom stems and revision meetings. If you need licensing context, start from our royalty-free music generator hub. Sound design is separate, so use game sound effect ideas for hits, pickups and UI clicks.
Frequently asked questions
How do I make a music loop for a game?
Generate the cue with a fixed BPM, key and loopable feel, then edit the loop in an audio editor. SoundUser tracks have natural endings, so set your grid to the prompt BPM, cut on a bar boundary and crossfade the tail into the head. If the ending has a final crash, regenerate with no final hit or steady groove to the end.
What BPM is good for combat music?
Combat music usually works at 130-170 BPM. Use the lower end for tactical, heavy or stealth combat, and the upper end for arcade action, chase scenes or bullet-heavy fights. Add a pulse that reads in gameplay: kick, toms, ostinato strings, synth bass or palm-muted guitar. Keep the key fixed if you need calm and combat variants.
Can I make chiptune or 8-bit music?
Yes. Use a prompt with chiptune, 8-bit or 16-bit, then name the chipsynth parts: square wave lead, pulse bass, triangle arpeggios and noise hats. A useful range is 120-160 BPM for action or overworld themes. Avoid stacking orchestral instruments unless you want a modern retro hybrid rather than a strict chip cue.
Can I make several versions in the same key?
Yes. Keep the same BPM, key, motif words and core instruments, then change the intensity layer. For example, write one G major town prompt at 82 BPM, then make a tense version by adding low strings, soft toms and darker pads. This helps variants swap more cleanly in a game editor.
Can I use the music in a commercial game?
Tracks you create are yours to use in your own projects, including commercial ones, under the SoundUser Terms Keep your prompts, dates, exports and project notes as records for your game build. Also check the rules for your storefront, publisher, jam, mod platform or client contract, because those requirements can be separate from what the generator provides.
How do I make a boss theme?
Start with tempo, key and threat level. A strong boss prompt might use 150-170 BPM, D minor, low brass, taiko drums, choir hits, string ostinato and distorted bass. Ask for instrumental unless you want voices. If it feels too heroic, add darker harmony and remove bright lead synths or major-key language.
Should I generate one long track for the whole level?
Usually not. Make one cue per gameplay state: exploration, danger, combat, boss, victory and defeat. Shorter functional cues are easier to loop, replace and balance under sound effects. Keep related cues in the same BPM and key when you want smooth transitions, and change both when you want a clear scene break.
