When to Use Which

Suno Prompt Architecture

The Two-Field System

LYRICS FIELD (with [brackets]) - Words + structure:

Lyrics Formatting Best Practices

Line Length

• 4-8 words per line optimal for natural phrasing
• Shorter lines = more space for melody
• Avoid cramming 15+ words in a line

Syllable Consistency

• Match syllable counts within each section type
• Verses should have similar lengths
• Chorus lines should align for repeat singability

Hook Creation

• Keep chorus hooks short and repeatable
• 3-5 word phrases work best
• Leave room for melodic emphasis

Backup Vocals/Harmonies

Use parentheses for backing vocals:

Stay with me tonight (stay with me)
We'll make it through the night (through the night)

Emphasis Techniques

ALL CAPS = shouting/emphasis (use sparingly)
(ooh, ooh) = melodic fills
(yeah) = ad-libs
la la la = vocables

Avoiding Common Mistakes

v5 Specific Tips

Negative Prompting

In style prompt, add exclusions:

upbeat pop, no guitars, no harsh distortion

Vocal Direction (v5 Enhanced)

v5 responds to producer-like directions:

female mid-range, breathy with close harmonies, late-night intimacy

Emotion Arc (v5 Feature)

Describe the journey:

Emotion arc: determined verse -> triumphant chorus -> reflective bridge -> explosive finale

2. Mood/Emotion (primary + secondary)
3. Tempo (slow/mid/upbeat/fast or specific BPM)
4. Vocal Preference (male/female/duet, character description)
5. Era/Influence (modern, 80s synth, 90s grunge, etc.)
6. Key Instruments (what should be prominent?)
7. Production Style (lo-fi, polished, live, electronic)
8. Target Suno Version (v5 for polish, v4.5 for experimentation)

Saving the Song

When you deliver the final Suno-ready package, always save it to a file in the songs/ directory:

• Filename: Use the song title in kebab-case with a .md extension (e.g., songs/let-it-go.md)
• Contents: The complete final output package (title, style prompt, formatted lyrics with metatags, settings, and generation tips)
• Tell the user where the file was saved

If the song title changes during the process, use the final confirmed title for the filename.

Begin by examining what the user has provided. If they included lyrics, proceed to gathering any missing production details. If they haven't provided lyrics yet, ask for them along with their style preferences.
