Guitar Chord Progression Generator

StrumForge generates four-chord progressions made for guitar. Choose a key, mode, style, and chord type, then hear the loop with groove playback while following the guitar diagrams. Keep the chords that work, replace the ones that do not, and try different voicings without rebuilding the progression from scratch.

  • Generate a four-chord progression in any available key or mode
  • Follow guitar chord diagrams during playback
  • Choose open, barre, triad, power, seventh, or sus / add9 options
  • Lock, replace, reorder, and revoice individual chords

Generate a progression you can immediately play on guitar

StrumForge creates one four-chord loop at a time. Each result includes guitar diagrams and playback controls, so you can judge the progression by how it sounds and how the chord changes feel under your fingers.

Leave the key open when you want a broad starting point, or select a key and mode when you want the harmony to stay within a particular sound. Chord filters determine which types of guitar shapes and chord colors can appear.

How to use the guitar chord progression generator

  1. 1. Choose a key

    Select a specific key when you want a defined tonal center. Leave Key set to All when you want StrumForge to choose from the available keys.

  2. 2. Choose a mode or use Auto

    Use Auto for a broad selection of progression types, or select one or more modes when you want a particular harmonic framework.

  3. 3. Select the chord options

    Enable Open chords for familiar full shapes, Barre chords for movable voicings, Triads for compact shapes, or Power chords for root-and-fifth movement. Enable 7ths or Sus / add9 when you want those supported chord colors to appear.

  4. 4. Generate and listen

    Select Generate to create a four-chord progression. Use the chord and rhythm playback controls to hear the loop with the selected groove, meter, guitar sound, and tempo.

  5. 5. Refine the result

    Lock any chord position you want to keep. Replace individual chords manually, drag the four cards into a different order, or cycle through available voicings for the same chord.

  6. 6. Use the scale view

    Open the scale or pentatonic view when you want to improvise, write a riff, or understand the notes surrounding the progression. Treat the diagrams as a visual reference.

Structured generation rather than four unrelated chords

StrumForge introduces variation within its progression system instead of selecting four completely unrelated chord names. The active key, mode, style, and chord options influence the result, while the diagrams ensure that each displayed chord has a supported guitar voicing.

Want the widest possible variation? Read the guide to using the random guitar chord generator.

What can you change after generating?

Keep a chord

Lock a chord position before generating again when you want it to remain part of the next variation.

Replace a chord

Select the chord name to choose a different supported chord for that position. The guitar chord maker guide covers manual chord selection and voicing comparison in more detail.

Change the order

Drag the cards to test whether the same four chords work better in a different sequence.

Try another voicing

Use the voicing controls to cycle through available guitar shapes for the same chord. A new voicing changes where and how the chord is played without changing its harmonic name.

Change the playback

Adjust tempo, meter, groove, and guitar sound to hear how the same progression responds to a different rhythmic setting.

Eight guitar chord progressions to try

These fixed examples demonstrate different ways to use the generator. Each one contains exactly four chord positions.

  1. Familiar major-key progression: G, D, Em, C

    Formula: I–V–vi–IV in G majorThis widely used movement is a practical starting point for testing strumming patterns and comparing open, barre, and triad voicings.Playing idea: Play one downstroke per chord first, then introduce a busier rhythm once every change is clean.Open this progression in StrumForge

  2. Relative-minor starting point: Em, C, G, D

    Formula: i–VI–III–VII in E minorThis uses the same chord family as a G-major progression but places Em at the center of the loop.Playing idea: Keep Em and C restrained, then increase the strumming intensity across G and D.Open this progression in StrumForge

  3. Suspended dominant color: D, Asus4, Bm, G

    Formula: I–Vsus4–vi–IV in D majorAsus4 delays the more settled sound of A major while preserving the progression’s dominant movement.Playing idea: Briefly alternate Asus4 and A before moving to Bm.Open this progression in StrumForge

  4. Major-seventh turnaround: Dm7, G7, Cmaj7, Am7

    Formula: ii7–V7–Imaj7–vi7 in C majorThe first three chords create a clear ii–V–I resolution before Am7 turns the loop back toward Dm7.Playing idea: Compare full seventh-chord shapes with smaller voicings higher on the neck.Open this progression in StrumForge

  5. Basic blues movement: A7, D7, A7, E7

    Formula: I7–IV7–I7–V7 in AThis four-position loop isolates the central I, IV, and V movement used in blues harmony. It is not a complete twelve-bar blues.Playing idea: Try the same chord sequence with a shuffle feel and straight eighth notes.Open this progression in StrumForge

  6. Power-chord riff prompt: E5, G5, D5, A5

    Root movement: 1–♭3–♭7–4 from EBecause power chords omit the third, the rhythm and riff around the roots can strongly shape the final character.Playing idea: Use palm-muted eighth notes, rests, and accented chord hits rather than holding every chord for the full measure.Open this progression in StrumForge

  7. Minor progression with a dominant return: Am, F, Dm, E7

    Formula: i–VI–iv–V7 in A minorE7 contains a stronger pull back to Am than Em would, giving the final position a clear turnaround function.Playing idea: Leave more space on the first three chords and accent E7 before the loop repeats.Open this progression in StrumForge

  8. Mixolydian-style movement: D, C, G, Am

    Formula: I–♭VII–IV–v in D MixolydianThe lowered seventh and minor fifth chord prevent the loop from resolving like a conventional D-major progression.Playing idea: Use a D Mixolydian diagram as a starting reference for a short melody, then emphasize notes from the current chord as the harmony changes.Open this progression in StrumForge

Create a new four-chord progression

Four ways to use a generated progression

Chord-change practice

Lower the tempo and loop all four chords. If one transition remains uneven, practice only those two chords before returning to the complete loop.

Songwriting

Repeat the progression while testing a vocal melody, guitar riff, or rhythmic motif. Change one chord only when the existing loop gives the melody nowhere useful to go.

Improvisation

Choose a scale diagram related to the selected key and mode, then listen for how individual notes interact with each chord. A diagram is a reference, not a guarantee that every note will sound equally resolved.

Voicing practice

Play the same progression with open chords, movable barre shapes, or smaller triads where supported. This keeps the harmony consistent while changing the register and fretting-hand movement.

Hear the progression as a loop

Chord names do not reveal timing, rhythm, or how strongly one chord leads into the next. StrumForge plays the progression with the selected guitar sound and groove while highlighting the active chord card.

Use the tempo control to slow down difficult changes. Turn the chord or rhythm audio on and off independently when you want to focus on your own rhythm playing.
