Comparing A natural minor (A-B-C-D-E-F-G-A) to A major (A-B-C#-D-E-F#-G#-A), which scale degrees have been lowered in natural minor?
AThe 3rd, 6th, and 7th scale degrees
BOnly the 6th and 7th scale degrees
COnly the 3rd scale degree
DThe 2nd, 6th, and 7th scale degrees
Natural minor lowers three scale degrees from parallel major: the 3rd (C instead of C#), the 6th (F instead of F#), and the 7th (G instead of G#). The most common misconception is that only the 6th and 7th are lowered — possibly because those are the changes that distinguish natural minor from harmonic minor (which raises the 7th back up). But the lowered 3rd is the most perceptually important change: it is the first thing a listener hears when a minor scale or chord sounds 'darker' than its major counterpart.
Question 2 Multiple Choice
D natural minor has the same key signature (same set of pitches) as which major scale?
AF major — D natural minor starts on the 6th degree of F major
BD major — parallel scales share the same tonic
CB♭ major — because B♭ major contains a flattened note like D minor
DA major — because A is the relative minor of C major, and D is nearby
To find the relative major of any minor key, go up three semitones (a minor third) from the minor tonic: D + 3 semitones = F. F major and D natural minor share the same seven pitches and the same key signature (one flat: B♭). Confusing relative and parallel relationships is the classic error here: D major is the *parallel* major (same tonic, different key signature), not the *relative* major. The relative major/minor pair shares a key signature; the parallel pair shares only a tonic note.
Question 3 True / False
A natural minor and C major contain exactly the same seven pitches, differing only in which note is treated as the tonic.
TTrue
FFalse
Answer: True
This is the defining relationship between a relative major and minor pair. C major (C-D-E-F-G-A-B) and A natural minor (A-B-C-D-E-F-G) use identical pitch content — all white keys on the piano. What makes them sound different is not the notes themselves but which note functions as 'home': the tonic that phrases gravitate toward and resolve to. In C major, C is home; in A natural minor, A is home. The shift in tonal center completely transforms the character of the same seven pitches.
Question 4 True / False
The 7th scale degree in natural minor functions as a leading tone, with a strong pull toward the tonic just as in major scales.
TTrue
FFalse
Answer: False
In natural minor, the 7th degree is a whole step below the tonic (a *subtonic*), not a half step. The leading tone in major is a half step below the tonic, creating strong upward pull toward resolution. In A natural minor, the 7th is G (a whole step below A), which has a much weaker tendency to resolve upward. This weakened cadential pull is why composers who wanted strong resolution in a minor key raised the 7th by a half step, creating the harmonic minor scale. Understanding the subtonic versus leading-tone distinction is essential for understanding why so many minor-mode compositions use harmonic rather than natural minor.
Question 5 Short Answer
Why do composers sometimes use harmonic minor instead of natural minor, and what specific feature of the natural minor scale motivates this choice?
Think about your answer, then reveal below.
Model answer: Composers use harmonic minor when they want a strong leading tone — a note a half step below the tonic that pulls strongly upward to resolve. Natural minor's 7th scale degree is a whole step below the tonic (a subtonic), which creates a much weaker sense of resolution at cadence points. By raising the 7th degree a half step (in A minor: raising G to G#), harmonic minor restores the leading-tone pull of major, making final cadences more conclusive and dramatic. The trade-off is that this raised 7th creates an augmented second between the 6th and 7th degrees, giving harmonic minor its distinctive exotic sound.
The subtonic-versus-leading-tone distinction is one of the most musically consequential differences between scale types. It explains why natural minor sounds more open-ended and modal, while harmonic minor sounds more harmonically driven and 'classical.' Most tonal music from the Baroque and Classical periods that uses minor keys relies on harmonic or melodic minor rather than natural minor precisely for this reason — the need for a conclusive dominant-to-tonic resolution requires the leading tone.
