The three chord trick and the blues
Why is the ‘Three-Chord Trick’: the very foundation of Western popular music from blues and rock ‘n’ roll to punk and heavy metal?
Despite the seemingly limited musical boundaries of three major triads, the I, IV and V chords allow songwriters a full range of permutations for the very strongest of voice-leading as well as the most powerful root movements in music – fourths and fifths.
‘In Spite Of All The Danger’ illustrates how the band began composing within the confines of I, IV and V, grasping the simple functions of each of these elements. It uses these three chords in the key of E, E is the I chord, A is the IV and (the no-longer-elusive) B7 is the V7 chord.

How does the song In Spite Of All The Danger illustrate how the Three-Chord Trick fulfils the important principles of most tonal music?
First, the need for movement away from the tonic I chord to create a sense of harmonic development. The IV chord, or subdominant, is built on the fourth degree of the major scale and represents a typical destination for the song to progress to before making its way back to I. The progress to the IV chord can be direct from the tonic, as in the case of bar 5 here – or indeed any typical blues.

Second, the blues creates a climax, a point of maximum tension which is then resolved, or ‘un-wound’, by means of a resolution back to the tonic, completing a sense of returning home after the journey. As we know this is a role typically played by the V chord (as here), with the B7 in bar 8 being followed by E. But as well as the ‘perfect’ V-I move, we can also see an alternative resolution, IV-I (albeit only as a brief turnaround gesture in bar 7), an important move found in many different contexts,
The first thing to notice is the presence of a flattened seventh on all the triads – not just the V as we would expect from major scale theory. This is characteristic of the blues (and many other Three-Chord Tricks, even if they do necessarily have an intrinsically bluesy flavour). The purpose of the flat 7 in each chord here is to complement the blues-based melodies whose chief source is the minor pentatonic scale that consists of the tones 1-flat 3-4-5-flat 7. The presence of the flat 7 in the I and IV chords is the first such exception to ‘the rules’ of major scale harmony. The tonic minor pentatonic scale can also be seen to contain the flat 7 of each of the I, IV and V chords, thereby explaining their presence in terms of a self-contained ‘blues theory’.
For You Blue
Bar 1 Bar 2 Bar 3 Bar 4
/ D7 / G7 / D7 / D7 /

Bar 5 Bar 6 Bar 7 Bar 8 / G7 / G7 / D7 / D7 / sweet and lovely girl its true Bar 9 Bar 10 Bar 11 Bar 12 / A7 / G7 / D7 / A7 / love you girl I do V7 IV7 I7 V7
It is mainly as a result of the influence of Afro-American blues, which adopts this scale wholeheartedly, that popular music is so difficult to pigeonhole in terms of Western diatonic theory. The presence of the 7 in the I and IV chords is the first such exception to ‘the rules’ of major scale harmony. Watch how, in ‘For You Blue’ the tonic minor pentatonic scale can also be seen to contain the 7 of each of the I, IV and V chords, thereby explaining their presence in terms of a self-contained ‘blues theory’.

Can the rules of 12 bar blues be broken?
Certainly, the rules of the 12-bar format where I, IV and V appear in certain prescribed sequences have always been broken. Songs of 8-, 11-, 13-, 16- and 24-bar sequences were regularly being explored by Delta bluesman as far back as Robert Johnson, Charlie Patton and Son House.
In music, an eight-bar blues is a common blues chord progression. Music writers have described it as “the second most common blues form”

The power of I – the one-chord trick
Songs do not necessarily have to revolve around even as many as three chords to create interest. ‘Tomorrow Never Knows’, the closing track on Revolver and sometimes regarded as The Beatles’ most progressive outing, is paradoxically structured around a single, simply embellished G chord, around which hypnotic modal melodies work their textural magic.

While harmonic stability is a strong tradition of Indian music like in Tomorrow Never Knows’, the same is also true of blues and rock ‘n’ roll. Indeed, the effect of a single chord throughout a song is an old blues tradition dating back at least as far as Charlie Patton’s 1929 recordings; while such droning blues harmony can still be heard in the ‘crossover’ blues sounds of R.L. Burnside.
The power of I – the one-chord trick
The British rock scene of the sixties was perhaps most directly introduced to this harmonically static sound through bands like the Yardbirds, with their renditions of songs like Willie Dixon’s ‘Smokestack Lightning’, featuring a repeated riff in E.
The power of I – the one-chord trick
And while one-chord songs are exceptions in pop music, many three-chord songs also make the important premise of establishing a prolonged tonic.
As McCartney remembers, one of the perennial Cavern crowd-pleasers was The Beatles’ cover of ‘Searchin”, a Three-Chord Trick, but one that hangs on the I chord for what seems like an eternity, as if stubbornly intent on going nowhere. Just listen to The Beatles’ version on Anthology 1 which, like the Coasters’ original, hangs on the tonic A chord for 16 bars before finally giving way to a IV chord.

That’s not to say that such ‘harmonically challenged’ songs have no ability to arouse interest. Indeed, such a device can be used effectively to create precisely this false sense of security. Take such influential early skiffle numbers as ‘Rock Island Line’, one of John Lennon’s earliest influences.
the revolutionary sixties version saw Lonnie Donegan strumming a lone G chord – unaccompanied for over a minute – before picking up steam and exploding into life with D and C chords. Such songs were perhaps unusual influences for The Beatles, whose original songwriting would soon be defined by relentless harmonic movement. Yet, as a principle to exploit in a pop song, an extended I chord would even find its way into several Beatles songs.

The power of I – the one-chord trick
in the context of a more conventional pop song, ‘Paperback Writer’ can clearly be seen to be built essentially around a similarly prolonged, scene-setting I chord that only makes a brief excursion to IV after a full 8 bars.
The power of I – the one-chord trick
Several other Beatles songs in a harder, blues-rock vein display this same, similarly stubborn, opening emphasis.
‘Everybody’s Got Something To Hide Except For Me And My Monkey’, for example, features a ten-bar, driving E tonality for both a four-bar intro and the first six bars of the verse.
The power of I – the one-chord trick
‘Ticket To Ride’ is most certainly not a Three Chord Trick, but this same ten-bar establishment of the tonic occurs here too.
This time a fourbar intro on A major is followed by another six bars in the verse before the first harmonic change. In terms of subtle semantics, it’s no accident that the lyrics “going away” prompts the shift from our stable tonic ‘home’.
The above examples are intended to familiarise the reader with the idea of establishing a tonal centre in a pop song and showing how a sense of anticipation is built up for the first impending chord change. The Beatles’ sense of harmony may, for once, be taking a back seat here, but the static premise nevertheless provides a backdrop for other musical highlights – in the case of ‘Ticket To Ride’, the guitar motif that lends interest by adding a 9th ‘colour’ tone, not forgetting the song’s famous lilting, syncopated drum beat.

What are colour tones and how are they used to dress up the I chord?
On the subject of ‘colour’ tones, the I triad, just like the V chord in the last chapter) can be dressed up in a variety of ways beyond the extension of the flattened 7th in a blues context. And The Beatles experimented liberally with everything from major 6ths, 7ths and 9ths, through to 6/9s, 7#9s, ‘11ths’ as well as ‘sus’ and ‘add’ chords, to vary the quality of the major I chord.
What is The Chuck Berry rhythm?
the rock ‘n’ roll guitar pattern popularised most famously by Chuck Berry. This involves first reducing each of the I, IV and V triads to a two-note diad consisting of a basic root-and-fifth perfect interval, omitting the third degree altogether. From there, a brief extension from the fifth to the sixth degree (and sometimes on to 7) can be made. This was standard R’n’B guitar practice in the early fifties and can be heard on early Beatles covers.
How is the G5 used in Yesterday?
fuller ‘5’ chords whereby the root and fifth (without the extra embellishments) are doubled in higher octaves in open positions on the guitar. This structure would create an important sound in rock, most notably in the chord shapes of Pete Townshend. It is also responsible for the droning, modal sounds in several Beatles ballads. Listen to the start of ‘Yesterday’ to sample McCartney’s ‘no thirds’ G5 shape

Similarly the D-shaped equivalent on the guitar would create an important folk-sound on Beatles songs like ‘You’ve Got To Hide Your Love Away’, ‘Norwegian Wood’, ‘If I Needed Someone’
