Progression I–vi–ii–V: chords in every key

The progression begins on degree I, moves to vi, reaches ii, and ends on V. In C major, the sequence is C, Am, Dm, and G. The first chord establishes a home base. The second keeps notes from the key but changes major rest into a minor color. The third prepares the arrival. The fourth creates the clearest tension and points back to the first chord.

The complete movement relates to the circle of fifths, but one distinction helps you study it more precisely. The vi–ii–V–I section follows a chain of descending fifths in its roots: A to D, D to G, and G to C. The I–vi passage connects C to Am by a third, not by a direct fifth. Thus, I–vi–ii–V combines a tonal opening with the classic preparation-and-resolution section.

In C, you can visualize the chord notes like this:

• C: C, E, and G.
• Am: A, C, and E.
• Dm: D, F, and A.
• G: G, B, and D.

Notice the shared notes. C and Am have C and E. Am and Dm have A. Dm and G have D. G and C have G. These connections reduce the distance between voices and help the cycle repeat without sounding like separate blocks. On keyboard, keep common tones when the voicing allows it. On guitar, choose nearby shapes before reaching for widely separated open chords.

When G returns to C, the ear recognizes the resolution. Then C can immediately begin another cycle. This dual function gives the progression continuous motion. In a pop or worship arrangement, the return supports the groove and leaves room for guitar, piano, bass, percussion, and voice. In a folk or blues setting, the same direction can support passing lines, neighbor tones, and more active counterlines.

Compare the cycle with the ii–V–I progression. In C, it uses Dm, G, and C. I–vi–ii–V adds C and Am before that resolution. You gain an initial preparation measure and a relative-minor color. To hear the difference today, play four cycles of Dm–G–C and then four cycles of C–Am–Dm–G, keeping 66 BPM.

Degree I serves as the tonal reference. In C, the C chord tells the ear where the music can rest. Play it with a firm attack on beat 1, but avoid sustaining every string with the same intensity. On guitar, try a voicing with the notes spread from low to high and keep the vocal range above 200 Hz if you are recording. The goal is to establish home without covering the melody.

Degree vi is the tonic’s relative minor. Am shares C and E with C, but puts A in the bass and changes the feeling. This chord often works well for lowering the dynamics. Play C at level 7 on a scale from 1 to 10 and Am at level 5. The difference should be audible without breaking the pulse. In a country ballad, this point can receive a more spacious arpeggio. In worship music, it can support a long vocal note.

Degree ii has predominant function. Dm leads to G because the D–G movement prepares the dominant. Do not treat ii as a new point of rest. Hold its duration, but keep the phrase moving. On piano, use Dm7 with F on top and then G7 with F or B on top, depending on the melody. On guitar, try Dm7 and G7 with two common tones or the smallest possible distance between voices.

Degree V concentrates the tension. In C, G or G7 presents B, the leading tone of C, and that note tends to rise to C. If you play G7 and resolve to C, try keeping F moving down to E. This small internal motion makes the resolution clearer than simply changing an entire chord shape. If the melody already uses B or F, choose an inversion that does not create a prolonged clash.

Think in four gestures: present, darken, prepare, and resolve. This map guides dynamics, duration, and register. If the voice sings loudly on G, reduce the right-hand force so you do not compete for space. If the voice is low, let the dominant have more attack and sustain the arrival on C for at least two beats.

In a samba groove, the bass can reinforce A–D–G–C while the accompaniment creates syncopations. Harmony indicates the destination. The groove determines when the body feels each step. To test this relationship, play only the roots with your thumb for two cycles. Then add chords on the offbeats without changing the bass line.

Begin with one chord per measure in 4/4. Play C in measure 1, Am in measure 2, Dm in measure 3, and G in measure 4. Count “1, 2, 3, 4” before each change. Use the metronome between 60 and 72 BPM. At 60 BPM, each cycle lasts 16 seconds. At 72 BPM, it lasts approximately 13.3 seconds. This range gives you time to check each change without turning the exercise into a speed test.

Do 10 cycles without stopping. If you make a mistake in the second measure, continue with the chord planned for the third. At the end, note how many changes landed before or after beat 1. An error that happens four times at the same point calls for an isolated two-measure exercise, not more speed.

Next, anticipate the entrance of the next chord. Keep the new chord’s bass on beat 1 and attack the right-hand shape on the “and” of the previous beat 4. Count “1, 2, 3, 4 and” and prepare on the final “and.” Start at 54 BPM with only one four-measure cycle. Move to 66 BPM when the anticipation no longer displaces the pulse.

Another division places two chords in the same measure. Play C on beats 1 and 2, Am on beats 3 and 4, then Dm on beats 1 and 2 and G on beats 3 and 4. The complete cycle now occupies two measures instead of four. The function remains, but the phrase becomes more active. If your left hand tenses or the bass loses clarity, return to one chord per measure.

In pop, rock, and folk music, the change may fall on beat 2, the offbeat of beat 4, or immediately before beat 1. The location depends on the melody, bass design, and arrangement convention. When listening to a recording, do not try to copy an entire chord chart. Mark only the pulse with your hand and make a note when you hear the harmonic change. In 60 seconds, you will have a map of the entrances without reproducing the song.

The online metronome helps compare these positions. First let the click mark all four beats. Then feel the click on beats 2 and 4, a useful reference for backbeat-based styles. If the browser metronome stops or the audio fails, check the volume and open tab. The tool depends on browser playback; it does not replace counting with your body.

Use the same sequence to test four settings. In the study version, attack one chord on beat 1 and let it ring until the next measure. In a ballad version, play an arpeggio of eight eighth notes per measure. In a pop or rock version, emphasize the offbeats and mute part of the strings. In a country version, keep the bass clear and reduce high attacks to leave room for the rest of the arrangement.

Begin with four regular attacks per measure. Play “1, 2, 3, 4” with the right hand, using force 4 on a scale from 1 to 10. Do the cycle for four rounds. This exercise shows whether the left hand changes without noise, whether the chord lasts for the agreed duration, and whether the pulse stays constant.

For a guitar groove, mark the bass on beat 1 and answer with short chords on the offbeats. Count “1 and 2 and 3 and 4 and.” Play the low note on 1, one chord on the “and” of 2, another on the “and” of 4, and leave silence at the other points. Then create a second version with an attack on the “and” of 1 and the “and” of 3. The silence must have a defined duration. Do not brush all six strings on every attack.

In a pop groove, separate three functions: bass, response, and muting. The thumb marks a low note on beats 1 and 3. The fingers respond on the offbeats. The side of the hand cuts off part of the sound on beats 2 and 4. Play at 76 BPM and record four cycles. If the bass and response blend together, lower the thumb’s volume and make the high attack shorter.

In country, try a bass figure on beat 1 and a dry chord on beat 2, repeating the idea on beats 3 and 4. At 96 BPM, keep the right hand small and even. In a country ballad, slow to 68 BPM and use arpeggios with thumb, index, middle, and ring fingers. Let Am last one extra eighth note when the melody calls for a passing feeling, but make G resolve clearly to C.

A useful variation keeps the right-hand pattern the same across all four chords and changes only the dynamics. Play I with force 6, ease off on vi to force 4, grow on ii to force 5, and sustain V with force 6. Then reverse it. Record 60 seconds on your phone. Listen for whether the dominant leads to I or whether all the chords have equal weight.

If you study music theory while practicing, name each event: pulse, offbeat, anticipation, muting, or silence. This prevents the hand from repeating a pattern without intention. Make a mark in your notebook whenever a chord enters late. Five marks in the same place indicate that you should slow down and practice only the transition between those two chords.

Sevenths make the chord functions more defined. In C major, try Cmaj7, Am7, Dm7, and G7. Cmaj7 adds B. Am7 adds G. Dm7 adds C. G7 adds F. Play each chord for one measure at 60 BPM and notice the note that remains between changes.

G7 makes the return to C more obvious because it contains B, which tends to rise to C, and F, which can fall to E. This voice leading happens inside the chord and does not require a complex groove. Dm7 softens the preparation for G7. Cmaj7 opens the tonic, but it can clash with a melody that holds B for a long time. If that happens, return to plain C.

sus4 replaces the third with the fourth. In Gsus4, C suspends G’s major definition and can resolve to B before C enters. Play Gsus4 for two beats, G7 for two beats, and C for one measure. This sequence creates a tension-and-resolution gesture within the same passage. Use Csus4 before C when the melody allows F to resolve to E.

Do not hold the suspension for four measures simply because the shape is available. The effect depends on when it resolves. To test it, compare three durations: Gsus4 for one quarter note, two quarter notes, and one full measure. The first creates a brief passing effect. The second makes the gesture audible. The third can compete with the melody and lose its passing function.

An inverted bass changes the lowest note but does not remove the chord’s main function. In C, try C/E to lead to Am. The sequence becomes C/E–Am–Dm–G. The bass passes through E before reaching A, reducing the leap between roots. Another option is Am/C, which brings the bass closer to Dm. Use one inversion at a time and listen for whether the bass line became more singable.

On piano, keep the right hand in a nearby register and move only the bass when possible. On guitar, choose an inversion that does not unintentionally put the third below the melody. On electric bass, confirm the root with the rest of the band before filling in with chromatic passages. A beautiful bass line should not hide the chord the other instruments need to recognize.

Test the changes in order. First use sevenths on all four chords. Then return to the simple shapes and apply sus4 only to G. Finally, keep the basic chords and change only the bass. If you alter voicing, extension, rhythm, and tempo at the same time, you will not know which choice changed the result.

To compare this path with another four-degree cycle, see the I–vi–IV–V progression. In C, the third chord of that sequence is F, while in I–vi–ii–V it is Dm. F functions as a major subdominant. Dm prepares G through a progression closer to ii–V–I. Play C–Am–F–G and then C–Am–Dm–G, keeping 72 BPM, to hear the difference.

Set a 15-minute timer and keep the same key on the first day. In C, spend three minutes on roots. Play C, A, D, and G in the bass or lowest register of your instrument. Count four beats per chord and quietly say “I, vi, ii, V.” The goal is to fix the order and locate the changes on beat 1.

For the next four minutes, use a simple right-hand pattern at 60 or 66 BPM. Do five cycles without stopping. If you miss a chord, do not return to the beginning. Mentally mark the measure of the mistake and continue until you complete the return to C. The progression must keep moving even when a change fails.

Reserve three minutes for a guide tone. Choose E, G, or C and play that note over all four chords. Notice how its function changes. Then use B over G and resolve to C when the next I arrives. While singing, sustain one note for four measures and listen to the effects of rest, passage, and tension. This exercise develops your ear without requiring many chords.

During the final five minutes, alternate two grooves. Do two cycles with regular attacks and two with offbeats. Record one version of each. Compare the timing of the changes, chord duration, and the strength of G7 or G. If the recording lasts 30 seconds, check whether you kept the tempo from beginning to end. A four-measure cycle at 60 BPM lasts 16 seconds, not counting an initial count-in.

On day two, transpose to G major: G, Em, Am, and D. On day three, use D major: D, Bm, Em, and A. On day four, try A major: A, F#m, Bm, and E. Keep the same groove and stay between 60 and 72 BPM. Changing keys shows whether you know the degrees or have only memorized the C shapes.

After a week, accompany a recording of pop, rock, folk, blues, or worship music using only the degrees. In country repertoire, notice when the sequence prepares a chorus entrance or a return to the verse. Listen for how bass and percussion change the feel of the measure. You do not need to transcribe the entire chart. Mark the key, pulse, and point where V returns to I.

If the change still feels uncertain, return to the chord generator and choose close voicings. On guitar, practice only the pairs C–Am, Am–Dm, Dm–G, and G–C for 60 seconds each. On piano, keep two or three common tones between chords when the melody allows it. Then resume the complete cycle and add sevenths, suspensions, and inversions one at a time.

1. Choose C major and write C, Am, Dm, and G in your notebook.
2. Set the metronome between 60 and 72 BPM.
3. Play one chord per measure for 10 cycles.
4. Record one cycle and check whether every change lands on the agreed beat.
5. Repeat only the pair that was late, such as Dm–G for two minutes.
6. Change the groove without changing the chords: regular attacks first, then offbeats.
7. Add Cmaj7, Am7, Dm7, and G7 only after the simple form is stable.
8. Transpose to G major and D major, keeping the same tempo.

When you finish, write down three details: tempo, number of uninterrupted cycles, and the least stable point. The next day, begin with the noted point. This record turns 15 minutes of practice into a sequence of concrete decisions.

• In C major, the cycle is C, Am, Dm, and G.
• The vi–ii–V–I section forms a chain of descending fifths in the roots; I–vi opens the cycle through a third relationship.
• I establishes rest, vi brings the relative-minor color, ii prepares, and V creates tension.
• Begin with one chord per measure in 4/4 and a metronome between 60 and 72 BPM.
• Test anticipations on the “and” of beat 4 only after beat 1 is stable.
• Change the groove, dynamics, register, and muting before changing the sequence.
• Add sevenths, sus4, and inverted bass notes one choice at a time.
• Practice 15 minutes a day and record the tempo, complete cycles, and error point.
