Chapter 3 Flashcards
The minor pop chords
How could the iii minor be used in a ‘I-vi-IV-V’ ?
Theory tells us that iii minor – being part of the tonic family – should be able to substitute for the ubiquitous vi chord within both our ‘I-vi-IV-V’ and also the Doo Wop version.
Can ii and V alternate on their own?
Yes. setting up gentle tension by delaying the cadence to I.
‘My Sweet Lord’ which features four repeats of ii-V before moving on to I.
Substitution summary – What is the concept of the diatonic ‘families’ ?
a songwriter can regard chords as not just being constructed from the parent diatonic scale but as belonging to smaller ‘families’ of chords within that harmonised scale. Indeed each of I, IV and V major triads can be seen as being ‘assigned’ minor chords to which they are related through either a major/relative minor relationship or just the sharing of common tones.
The Four-Chord Cycles revisited – ‘ii-V-I-vi’
If we now start the Doo Wop chord sequence a bar late, we arrive at an important variation: ‘ii-V-I-vi’
The sequence is used in ‘The Fool On The Hill’ (‘Nobody wants to know him they can see that he’s just a fool’ –
The ‘I-iii scale walk’ in the 12-bar blues
You can walk up for the I to the iii and then back down to the ii. Then end with a ii-V-I
-Heard in blues like Stormy Monday
What is the ‘I-iii’ move?
-should be seen as a dramatic departure from the now numbing predictability of the ‘I-vi’
-Its more slick sounding and is often used in the context of an opening change in a verse.
“I read the news today oh boy”
-Many of these songs then go on to the vi. “I-iii-vi”
What chords are in “The tonic family:” ?
I, vi and iii
What chords are in The dominant family ?
V and vii
What chords are in The subdominant family: ?
IV and ii
What is the iii chord called traditionally?
The iii chord is traditionally called the mediant, as it is the harmonic point mid-way between the tonic and the all important dominant. As a result, it represents root movement of a third interval from the tonic,
What is the diatonic Cycle Of Fifths ?
I-IV-VII-iii-vi-ii-V-I
a song can literally revolve around this cycle continuously or use it as a temporary stepping stone, a musical ‘merry-go-round’, jumping on and off at will.
Remember that the Cycle Of Fifths reflects root movement – not the quality of the chord built on that root.
Why should these ‘iii-vi’ moves ‘work’ ?
because of their root movement. For the iii lies a fifth above the vi and it therefore has a natural tendency to move to it, creating ‘stops’ along the Cycle Of Fifths,
What is The ‘I-vi-I-vi’ vamp?
This works because the vi is the relative minor of the I. In C, C major and A minor both have C and E notes. The I and vi are flipsides of the same coin
The Four-Chord Cliché – ‘I-vi-IV-V’
Used almost more then any other progression. Think “All I have to do is dream”
What is Diatonic substitution ?
when crafting a song, a writer will look for a chord that is different to the one that might have been expected – but which still enables the progression to function as he initially intended.
Can the ii minor be substituted for the IV chord?
yes. In any key, the ii minor is the relative minor of the IV chord and, as a result, the potential for substitution between the two chords exists.
What is the ‘ii-for-IV’ substitution (the Doo Wop cycle) ?
The four chord cliche but the formula is now spelt I-vi-ii-V
Think “Blue Moon”
What is the diatonic walk I-ii
The use of ii as the first step along the diatonic harmonized scale from the tonic
In the same way we saw I alternate with IV, we can do the same with ii. Think “Dont let me down”
You can also continue up. “Getting Better”
What does Ending a section with a prepared Perfect cadence do?
Simply by putting a ii minor chord ahead of the V, we are ‘priming’ the dominant and thereby encouraging the listener to hear the eventual movement to I from ‘further back’ in the sequence.
ii-V-I
Perfect Cadance ending a section
the ii-V-I here creates a feeling of a progression being self-contained, with a Perfect cadence taking us to a point of rest (this time with a melody that also homes in on the restful tonic). It creates a point of resolution, both musically, and semantically in terms of John’s sobering, soul-baring admission.
What is accomplished by Ending a section with an Imperfect cadence?
ii-V………………I
This ends not with a ii-V-I resolution but with the ii-V chords on their own. The tonic does follow – but only as we start the next verse after a notable delay in which we are left ‘hanging on the dominant’. The cadence is said to be Imperfect because of this ‘hanging effect’,
Why does the diatonic cycle of 5ths work?
I-IV-VII-iii-vi-ii-V-I
The cycle invariably ‘works’ because of the ebb-and-flow of tension and resolution that is naturally built into it, with the penultimate dominant V consolidating this flow of fifths as it cadences to the tonic.
Can ii-V-I be used cyclically?
Yes. The Beatles choose a cyclical ii-V-I, this time with psychedelic minor 7th and 6th extensions, for their ethereal vamp on ‘Sun King’.
How does Golden Slumbers use the diatonic cycle of 5ths?
I-IV-VII-iii-vi-ii-V-I
look at the symmetry of the sequence as the line ‘Sleep pretty darling’ cues the run E7-Am7-Dm7-G7-C. four of the seven diatonic chords in the harmonised major scale can work their way inexorably towards the final tonic destination in
one seamless run.
