Intermediate Chord Progression

Discover the most common variations to a Chord Progression!

In beginner chord progression, we learned about diatonic chord progressions (chords built off the major scale). It’s now time to study the most common variations.

The standard diatonic chords paired with the most common variations like IVm, IIIx and bVII is what makes up most chord progressions in popular music.

All these variations are very common and come from the Blues where we temporarily move between minor and major.


The I7 chord

When the Blues first began to evolve, being accompanied by a guitar, the instruments were of low quality with very high string action.

Therefore, the early blues musicians tuned their guitars to open major chords such as E, D, G and A. A bottleneck slide was then used to swap between the different chords in order to form a progression for the singer to tell their story over.

Instead of chord I being a major chord or when extended, a maj7, Blues musicians decided that a dom7 chord was a better idea. What’s more, they simply moved that whole pattern to fret five to get the IV chord and did the same thing there, so A7D7 for example.

Back in standard tuning and the clue to what this has done to modern songwriting can be seen in the chord shapes:

A7

A7

Notice that the 3rd is a C# (2nd string, 2nd fret)

A singer would choose to melodically phrase using these chord notes since they feel most comfortable to sing.

So over the A7 a singer naturally hits the notes: A, C#, E or G.

When we move to the next chord, the IV7, or in the key of A, a D7, we can see that the b7th interval is a C, not a C#.

D7

D7

Inside the chord D7, the b7 is a C, in relation to the A chord, this is a m3rd.

Moving from A7 to D7 is not harmonically correct. It should be Amaj7Dmaj7. What happens is that the D7’s b7th interval, the C, is a semitone away from the A7’s major 3rd interval, the C#.

To move between C# and C is like moving from A major to A minor.

This has had an incredible influence on vocal melody and the blues guitar solo where we constantly move between minor and major. Below is a video demonstration of this.

From A7 to D7, I play on C# to C. Coming back from D7 to A7, I play C to A, resolving “from minor” to the root of A.

From A7 to E7, I play the b7 of A. This is a m3rd of an E chord, which resolves up to a 3rd.

The last A7 to E is quick, but it does go b7 of A, up to 3rd of E, that’s G to G#.

Moving like this between minor and major sounded so good that it soon started being employed everywhere. In fact, any of the diatonic chords can be switched from minor to major as a result of it!


The IIx chord

Originally, chord II is a minor chord that belongs to the Dorian mode. When turned into major we call it a IIx chord, this means that the chord has temporarily changed, we haven’t changed key.

Should you be in C major then D (or D7 if extended) would be your IIx or IIx7 chord.

Very often, the IIx7 is followed by a V7 chord which is followed by chord I. This progression is a continuous move of ‘up a 4th’, using dominant chords.

Many songs use IIx7V7Imaj7 to vary the classic IIVI.

Chord IIx in songs

In the beginner and intermediate acoustic songs you’ll find IIx in these songs:


The IIIx chord

Whenever you change chord III, a minor chord, into a major chord you get the IIIx. This is by far the most common variation.

Let’s look at the key of C major, here we have an Em as chord III, change that to a IIIx and we get an E chord.

The main purpose of this chord is to steer more heavily towards chord VI, let’s look at why.

Am chord: A C E
Em chord: E G B, the G – A is a tone apart
E chord: E G# B, The G# – A is a semitone apart

The closer the intervals are to each other, the stronger the pull.

To learn the characteristic sound of the IIIx we need to look at our beginner and intermediate acoustic songs for it.

Chord IIIx in songs

  • One More Cup Of Coffee – The last chord of the progression is chord IIIx
  • Rewind – The pre-chorus starts with a IIIx, you will also find this in the second chord of m8
  • A Change Is Gonna Come – The IIIx appears briefly towards the end of the verse
  • Angie – The IIIx chord is the second played during the verse
  • Empire State Of Mind – The first chord of the bridge is a IIIx
  • Sunny Afternoon – All sections have chord IIIx present

There are many, many more examples of the IIIx chord among the advanced songs and master songs.


The bIIIx chord

If you change your III chord into a major chord and then flatten it a semitone you get your bIIIx chord. This chord holds extreme tension since most notes inside it is outside of the key.

Let’s look at the notes in C major:

C – D – E – F – G – A – B

The III chord is an Em (E – G – B), the bIIIx7, an Eb7 chord has the notes Eb – G – Bb – Db.

Only the G is still a part of the original key of C.

Chord bIIIx in songs

You can find it in these intermediate, advanced and master acoustic songs.

  • Beautiful – If seen as in the key of Ab, the last chord of the verse is bIIIx
  • I Can’t Stand The Rain – The third chord of the chorus is a bIIIx
  • Starman – Very briefly at the end of the verse we find a bIIIx
  • Blackbird – In the chorus, you could find a bIIIx although it is more of a key change this time
  • Take Me To The River – The bridge has a bIIIx chord
  • Tenderness – There’s a bIIIx with and without bass note variation

Perhaps a little complicated theoretically but at least it’s easy to spot when the bIIIx enters a song, extreme tension!

My favourite example of bIIIx happens in the third chord played in ‘Smells Like Teen Spirit’, so let’s hand over to Kurt and the boys for some bIIIx action!


The IVm chord

The IVm completely throws the feel of our normal IV chord out the window. The IV chord has a striving feeling, whereas the IVm has a slow down effect on almost any progression, especially when it is used after a normal IV chord.

Many songwriters secret weapon, the IVm is easily spotted by chord progression enthusiasts.

Chord IVm in songs

If you want to be able to recognise the sound of IVm you have to find her in songs, let’s take a look at these intermediate, advanced and master acoustic songs.

In my favourite IVm example, ‘Goodnight Sweetheart Goodnight’, the IVm really stands out, let’s have a listen. Can you work out when it appears?


The VIx chord

Another great trick for songwriters is to turn the usually sad chord VI into a major chord, this gives any song a surprise lift.

When extended I used to think that it’s always into a dom7 but recently I have been proven wrong (see below).

Usually, if it’s VIx, it’s just a major chord, rarely extended to dom7.

Check out these examples and see how you expect something sad to happen, but get happy!

Chord VIx in songs

  • Sunny Afternoon – When the chorus starts with VIx it really is a lift. Of course, this is also a key change, but when it first happens the sound is that of the VIx chord
  • Baby Won’t You Please Come Home – There is frequent use of the VIx throughout
  • Dream A Little Dream – The VIx appear in the verse, later a bVIIx joins the party
  • I Wish – The second chord of the bridge is a VIx. Although this is also a temporary key change, the sound of the uplifting VIx is lingering
  • Tenderness – The VIx appear in the outro

Estelle finds the VIxmaj7

In American Boy, the first chord of the verse (after the chord that slides in) is an Emaj7, this is a VIxmaj7 chord. The entire progression reads Emaj7Cmaj7Am7Fmaj7/D.

Just when you thought you’d heard it all…


The bVII chord

You have to look long and hard to find a VII chord in a song, but change it into a major chord and flatten it and all of a sudden it’s everywhere!

Perhaps the reason we so easily take to the bVIIx is because moving up a 4th from to another major chord is something we just like to hear.

So when a IV chord goes up a 4th and hits another major chord it just makes sense. In C major this would be F (IV) to Bb (bVII).

If you really want to go to town on this concept, start on IIx7 and just move up a 4th: D7 (IIx7) – G7 (V7) – C7 (I7) – F7 (IV7) – Bb7 (bVIIx7). Sounds pretty common to me!

Chord bVIIx in songs

  • Beautiful – If seen as in the key of Eb, the second chord of the verse is a bVIIx
  • I Can’t Stand The Rain – The first chord of the chorus is a bVIIx
  • Angels – Towards the end of the chorus, a bVIIx chord appears just as the lyrics read “I’m loving angels instead”
  • Stairway To Heaven – At the end of the verse if the song is seen as in the key of G
  • Take Me To The River – There is constant use of the bVIIx in this song
  • Dream A Little Dream – Find it as the last chord of the chorus
  • Tenderness – The bVIIx is here, but then again, what chord isn’t!
