Twitter Card: summary_large_image OG Image (16:9): REPLACE_VIP_OG_IMAGE_URL Image Alt (max 125): VIP Hook QA and Density System for AI songwriting on dark background VIP Deep Dive • Lyric Engineering #7 • Hook Quality Assurance This system audits your hook. It measures repetition, compression balance, anchor frequency, and cross-track differentiation. Purpose Turn instinct into measurable repeat value Applies To Singles • EPs • Mixtapes • Albums Part 1: Compression Differential Audit Chorus lines should typically feel lighter than verse lines. Not shorter for style — lighter for impact. Step 1: Count average words per verse line. Step 2: Count average words per chorus line. Step 3: Compare. If chorus matches or exceeds verse length, compression is likely needed. Goal Chorus feels cleaner than the verse. Part 2: Hook Density Score Repeat value is measurable. Hooks fail when every line introduces new information. Metric What to Check Anchor Frequency Does the anchor appear 2–4 times? Unique Idea Count More than 2 ideas reduces clarity Repeated Word Ratio Is repetition visible and intentional? If anchor appears once It is not yet a hook. Part 3: Anchor Stability Test Remove every supporting line. Does the anchor survive alone? If yes → strong primary anchor. If no → rebuild anchor before layering. Part 4: AI Stress Repeat Test Paste only the chorus into an AI chat tool. Ask it to repeat the hook in one line from memory. If it rewrites the anchor, clarity is weak. Pass Condition Anchor survives repetition unchanged. Part 5: Mixtape Differentiation Control Strong projects rotate hook shapes. Weak projects repeat the same hook structure every track. Track Type Hook Shape Track 1 Declarative anchor Track 2 Emotional anchor Track 3 Call & response Track 4+ Short chant-style Standard Simple hook. Different shape per track. Hook QA Console Module 1: Compression Audit Module 2: Density Scoring Module 3: QA Prompt TASK: Perform a hook quality audit. RULES: - Identify anchor phrase. - Measure anchor frequency. - Evaluate compression vs verse. - Flag excess unique ideas. - Suggest differentiation if needed. OUTPUT: 1) Anchor analysis 2) Compression note 3) Density note 4) Differentiation advice Pro FAQ Is repetition always good? Only when centered on a strong anchor. Weak anchors amplified by repetition feel irritating. Can a hook be too short? Yes. Minimal anchors must still carry emotional or identity weight. Why measure hooks? Because instinct fades across a project. Measurement maintains consistency. VIP Access
