:pushpin: Introduction

The following guide is a user-created usage manual shared by our Discord community. We’re reposting it here to help more users better understand Tunee’s system behavior and create more satisfying music with clearer guidance.

If you notice any areas that could be improved or have additional suggestions, feel free to reach out to our community moderators or supporters, or contact us directly at support@tunee.ai — we’re always happy to listen.

:cross_mark: Current System Limitations

At the moment, Tunee does not support the following use cases:

  • Cover songs, song remakes, or adding vocals in post-production
  • Extremely short audio (e.g. ringtones) or tracks longer than 8 minutes

:light_bulb: For best results, we recommend keeping tracks around 2 minutes

  • Instrumental continuation based on an existing instrumental track

:repeat_button: Smart Fallback Mechanism

To ensure overall generation stability, Tunee uses an automatic fallback system:

  • If a selected model becomes unavailable, the system will automatically fall back to a stable Mureka-series model
  • Your prompt content is preserved — only the sound character may change
  • As a user, you might notice:
    • The generation finishes unusually fast
    • The result sounds flatter or less layered than expected

This behavior is normal and helps prevent failed or interrupted generations.

:brain: Most Important: How to Write Stable Prompts

In practice, prompt structure is the single most important factor for achieving consistent and reliable results.

:white_check_mark: Four Essential Elements Every Prompt Should Include

  1. Genre
  2. Tempo / BPM
  3. Main instrument
  4. Mood or emotional direction

:musical_score: Recommended Prompt Templates

:microphone: Vocal Songs

[Intro] atmosphere + tempo + main instrument  
[Verse] calm vocals + core emotion  
[Chorus] brighter tone / increased energy  
[Outro] fading atmosphere

:musical_keyboard: Instrumental Tracks

instrumental track, clear tempo, main instrument, emotional flow, rich reverb

:cross_mark: Common Beginner Mistakes

  • Using only abstract descriptors (e.g. “beautiful”, “emotional”)
  • Asking for a song “like a specific singer”
  • Specifying exact bar counts or second-by-second timing
  • Giving contradictory instructions

For example: heavy drums combined with extremely wide spatial reverb

:warning: Important Reminder About “Don’t / Avoid” Prompts

Tunee generally performs better when you describe what you want to keep,
rather than listing what you want to remove.

Instead of negative instructions:

  • :cross_mark: “Don’t use heavy reverb”
  • :white_check_mark: “Clean, dry vocal mix with clear presence”

Rewriting constraints as positive descriptions usually leads to more stable and predictable results.

:check_mark: Final Tip

If a result doesn’t sound right, try adjusting the prompt structure first before running multiple generations.
Clear intent almost always works better than complex wording — small changes can make a big difference :musical_notes:
