The Chord Progression Cheat Sheet — Tags That Actually Steer Suno's Harmony

Suno doesn't accept chord names like "C — Am — F — G" directly, but it absolutely responds to progression descriptions in plain English. Most people leave this lever untouched. Here's how to use it.

The 5 progression archetypes Suno understands

1. Pop Cycle (vi-IV-I-V) — "Hopeful, Resolving"

Think Don't Stop Believin', Let It Be, Someone Like You.

"Warm and resolving chord progression, hopeful pop harmony, descending bass line"

2. Sad Cycle (i-VI-III-VII) — "Cinematic, Melancholic"

Think Beat It, Hello (Adele), Stairway to Heaven.

"Melancholic minor progression, cinematic descending chords, emotional release"

3. Blues / Rock (I-IV-V) — "Driving, Inevitable"

Think Sweet Home Alabama, Wonderwall, Take Me Home Country Roads.

"Classic 3-chord rock progression, driving and predictable, anthemic"

4. Jazz / Sophisticated (ii-V-I + extensions) — "Smooth, Resolved"

Think Autumn Leaves, Misty.

"Sophisticated jazz harmony, ii-V-I cadence, extended chords, lush"

5. Modal / Suspended — "Floating, Unresolved"

Think Riders on the Storm, modern lo-fi.

"Modal harmony, suspended chords, floating and unresolved, ambient"

Modifier words that shift Suno's chord choice

• descending bass — adds movement, classic pop
• pedal tone — same bass note, chords change above (atmospheric)
• key change at the bridge — Suno honors this
• borrowed chord — adds an unexpected major in a minor key (or vice versa)
• minor 4 (iv chord) — instant melancholy hit
• relative minor turn — emotional shift
• picardy ending — minor song ends on a major chord (hopeful close)

Emotional vocabulary that Suno maps to harmony

• bittersweet → minor key with major lifts
• triumphant → ascending major progression
• tense → minor with diminished or suspended chords
• nostalgic → vi-IV-I-V (pop cycle) with warm production
• dramatic resolution → V-i cadence emphasized
• dreamy → suspended chords, no resolution
• anxious → unresolved 7ths, modal
• confident → I-IV-V or major-only

The "key change" trick

Suno responds to explicit key change instructions in section headers:

[Bridge: key change up a step, brighter and bigger]
[Final Chorus: modulate up, anthemic finish]

This is the trick behind every emotional chorus lift. 80% of pop hits modulate the final chorus up a half-step or whole step. Suno will deliver if you ask.

Genre-specific harmony prompts

• Lo-fi: "Lazy jazz chords, suspended 9ths, pedal-tone bass, never fully resolves"
• Country: "I-IV-V country progression, descending bass walk, twangy"
• R&B: "Neo-soul harmony, extended 7th and 9th chords, jazz-influenced, smooth modulation"
• Cinematic: "Sweeping minor progression, descending cello, dramatic Picardy ending"
• House: "Suspended chord stabs, four-bar harmonic loop, building tension"
• Folk: "Simple folk progression in major key, capo'd guitar feel, organic"

Pro tips

• Don't try to specify exact chord names — Suno mostly ignores letter-name notation. Use feeling words.
• One harmony tag is enough. Stacking 3+ confuses Suno.
• The single biggest harmonic lift you can give a song: key change up a step at the final chorus. Try it on any song you love — it's transformative.
• Pair harmony tags with BPM — "melancholic minor at 70 BPM" hits very differently than "melancholic minor at 130 BPM".
• Modal/suspended progressions work best for instrumentals or ambient lyrical content. Pop cycles work for upbeat lyrics.
