2.1 Common Structure Tags

[Intro]       — Instrumental opening
[Verse]       — Narrative section, lower energy
[Pre-Chorus]  — Build-up before the chorus
[Chorus]      — The catchiest part
[Post-Chorus] — Extension after chorus
[Bridge]      — Break the repetition
[Interlude]   — Instrumental transition
[Outro]       — Ending
[End]         — Force stop

2.2 Practical Layout

[Intro]

[Verse 1]
First verse lyrics
go here

[Pre-Chorus]
Build-up lyrics

[Chorus]
Chorus lyrics

[Verse 2]
Second verse

[Chorus]

[Bridge]
Bridge lyrics

[Chorus]

[Outro]

[End]

2.3 Make Instrumental Sections Actually Instrumental

If you write [Intro] but AI still sings, try:

Method 1 — Leave it blank:

[Intro]

[Verse 1]
Lyrics start here...

Method 2 — Add description:

[Intro: Soft Piano, Building Atmosphere]

[Verse 1]
...

2.4 Pre-Chorus Tension Design

Pre-Chorus isn’t just “lyrics before chorus” — its job is to create suspense.

[Pre-Chorus: Building Tension, Drums Intensify, Rising Dynamics]
Lyrics...

Tension elements: Sixteenth Note Hi-hat, Snare Build, Bass Gets Busier, Strings Enter

2.5 Inline Tags

Insert these mid-lyrics for dramatic effects:

Tag	Effect
[Stop]	Sudden pause
[Break]	Brief rest
[Build]	Energy rising
[Drop]	Energy crash then爆发 (EDM)
[Whisper]	Whispered
[Spoken]	Spoken, not sung
[Scream]	Scream (metal/rock)
[Harmonies]	Harmony layers
[Fade Out]	Gradual fade

Example:

[Chorus]
Everything we used to have
[Stop]
Is over now
[Build]
But I still remember

2.6 Duration Control

Generate first → Crop to desired length → Extend if needed.

2.7 Chord Notation in Lyrics

Suno V5 recognizes chord markers in lyrics:

[Verse]
[Am] I hear the wind [F] blowing
[G] through that [C] silent forest

Use square brackets [] right before the lyrics syllable.

2.8 Key Change as Emotional Lift

Final chorus key change (half-step or whole-step up):

[Final Chorus: Key Change Up, Half Step Higher]
Last chorus lyrics...

In Style: Modulation in Final Chorus, Key Change Up, Emotional Lift

2.9 Force Ending Methods

Method 1 — [End] tag:

[Outro]
Last line...
[End]

Method 2 — [Fade Out]:

[Outro]
Last line...
[Fade Out]

Method 3 — Descriptive:

[Outro: Gentle ending, Final chord rings out]
[End]

Method 4 — In Style: Short song, 2 minutes, Clean ending

2.10 Hook Reinforcement

• Repeat key lines: (I won't let go) — parentheses = backing vocals
• Tag the hook: [Chorus: Catchy Hook, Memorable Melody]
• Use Post-Chorus: Add “Oh-oh-oh, yeah” after chorus to deepen impression

2.11 Time Signature Control

Default is 4/4. To change:

3/4 Time Signature, Waltz
6/8 Time, Compound Meter
5/4 Time, Odd Meter, Progressive

Time Signature	Feel	Typical Style
3/4	Graceful, swaying	Waltz, Folk
6/8	Flowing, lyrical	Irish Folk, Rock Ballads
5/4	Unstable, experimental	Prog Rock, Jazz

2.12 Swing & Groove Control

• Jazz/Blues: Swing Feel, Triplet Shuffle
• Funk: Funky Groove, Syncopated, Tight Pocket
• Reggae: One Drop, Off-beat Emphasis
• Neo-Soul: Lazy Groove, Slightly Behind the Beat

2.13 Sustained Notes & Ornamentation

• Extend with ～ or ---: Love you---
• Split syllables: lo-o-o-ove you for melisma
• Slide: (slide up) or (portamento)

2.14 Punctuation Effects on Vocals

Symbol	Effect
,	Short pause, breath
.	Longer pause, sentence end
!	Emphasis, energy lift
?	Rising intonation
…	Extended pause, hesitation
()	Harmonies / background vocals

2.15 Intro Type Variations

[Intro: Cold Open]           — Start at high energy
[Intro: A Cappella]          — Vocal only opening
[Intro: Instrumental Build]  — Instruments enter gradually
[Intro: Ambient Texture]     — Atmospheric铺垫
[Intro: Drum Count-in]       — "1, 2, 3, 4" start
[Intro: Sound Effect]        — SFX opening (rain, phone, etc.)
[Intro: Spoken Word]         — Spoken opening
[Intro: Hook Preview]        — Preview chorus melody
[Intro: False Start]         — Fake start then restart

2.16 Sudden Instrument Stop (Dramatic Effect)

[Outro: Solo Piano Returns, Intro Motif Reprise]
[End]

2.17 Outro Type Variations

[Outro: Fade Out]            — Gradual fade
[Outro: Cold End]            — Abrupt stop
[Outro: Reprise]             — Recall theme
[Outro: Deconstruction]      — Instruments exit one by one
[Outro: Tag]                 — Repeat last line
[Outro: Bookend]             — Call back to Intro
[Outro: Cliff-hanger]        — Suspense ending
[Outro: Ritardando]          — Gradually slow down
[Outro: Final Chord]         — Last chord rings
[Outro: A Cappella]          — Vocal only ending

2.18 Middle 8

Common in British pop — shorter and more distinctive than Bridge:

[Middle 8]
Contrasting section here
Different melody from verse and chorus
About 8 bars

Style: British Pop Structure, Middle 8 Section

2.19 Pre-Drop (EDM Specific)

[Pre-Drop: Build Up, Rising Tension]
Build-up elements
[Drop]
(instrumental drop)
[Post-Drop: Energy Sustain]

Build-up: Riser, Snare Roll, Filter Opening, White Noise Sweep, Vocal Chop Build

2.20 Tag Format Consistency

• Use consistent naming: [Pre-Chorus] not [Prechorus]
• Tags on their own line — don’t mix with lyrics
• Keep tags short and directive: [Verse 1: Sparse, Close Mic] NOT [Verse 1: This is a very emotional and beautiful section...]
