A songwriter trying to create a strong cadence uses the progression V–IV–I instead of IV–V–I. Why does the first feel weaker as a final cadence, even though it uses the same three chords?
AV–IV–I is weaker because the IV chord is higher in the scale than V, creating an awkward descent
BV–IV–I moves from high tension back through departure before arriving home, which interrupts rather than intensifies the pull toward resolution
CIV–V–I is stronger simply because it's more commonly used in Western music
DThe dominant (V) always sounds better when it comes last, just before the tonic
Harmonic function is directional: IV moves away from home (departure), V intensifies the need to return (tension), and I is arrival. In IV–V–I, the functions build logically: departure → intensification → resolution. In V–IV–I, the dominant creates tension but then the progression moves to subdominant — which is a 'departure' function — before arriving home. This releases some tension prematurely, weakening the final resolution. The functions are the same, but their order determines whether they accumulate or dissipate.
Question 2 Multiple Choice
What is voice leading, and why does it matter even when every chord in a progression is harmonically correct?
AVoice leading is the process of choosing which chord roots to use — it determines harmonic function
BVoice leading refers to the smooth or stepwise motion of individual notes between chords; it determines whether a progression sounds polished or clunky even when the chord symbols are right
CVoice leading is the assignment of chords to specific instruments or vocal parts
DVoice leading means the melody notes always belong to the current chord
Two progressions can use identical chord symbols (e.g., I–IV–V–I) but sound very different depending on how individual voices move between chords. Good voice leading means each part moves by step or holds a common tone, avoiding large leaps. A progression with correct harmonic function but poor voice leading will sound clunky — notes jumping around unnecessarily, parallel fifths creating acoustic roughness. The harmony provides the functional logic; voice leading provides the smooth surface that makes it convincing.
Question 3 True / False
The tension that makes the dominant (V) chord want to resolve to tonic comes partly from the leading tone — the note a half step below the tonic that creates a strong pull upward.
TTrue
FFalse
Answer: True
In a major key, the dominant seventh chord (V7) contains the leading tone (scale degree 7), which is a half step below the tonic. This creates strong voice-leading pressure toward resolution: the leading tone 'wants' to rise a half step to the tonic, while the seventh of the chord 'wants' to fall a step to the third of I. This double resolution impulse is why the V–I cadence is so satisfying and why the dominant has the strongest directional pull of any chord function.
Question 4 True / False
The dominant chord (V) is expected to typically appear immediately before tonic (I) — it cannot be followed by any other chord without destroying the progression's functionality.
TTrue
FFalse
Answer: False
This is one of the common misconceptions the topic explicitly addresses. V can resolve deceptively to other chords (such as vi in a deceptive cadence), and IV can lead directly to I in a plagal cadence without V at all. Conventions exist and are musically meaningful, but they describe tendencies and defaults, not inviolable rules. Composers exploit these tendencies for expressive effect — a deceptive cadence (V–vi) creates surprise precisely because it withholds the expected resolution.
Question 5 Short Answer
Why does the progression I–IV–V–I feel more satisfying than I–V–I, and what functional role does the IV chord specifically contribute?
Think about your answer, then reveal below.
Model answer: The IV (subdominant) adds a sense of departure and expansion before the tension of V. I–V–I is the skeleton of tonal motion, but it jumps directly to tension without first moving away from home. Adding IV between I and V creates a three-part journey: establish home (I), move away (IV), intensify the need to return (V), arrive (I). The IV chord also introduces a different quality of motion — it's restless but not as sharply tense as V — which makes the eventual V and then I feel more earned.
Think of IV as providing 'narrative arc' to the progression. A story that goes 'home → away → adventure → home' is richer than one that goes 'home → back home again.' The subdominant is the 'moving away' function; it prepares the dominant rather than competing with it. This is why the blues progression (I–I–I–I / IV–IV–I–I / V–IV–I–I) works: the IV adds expansiveness in measures 5-6, and the V in measure 9 feels like a climax precisely because the departure and return have been given space.
