Questions: Scale Degree Tendencies and Tonal Gravity

Question 1

A melody sits on fa (scale degree 4) and then leaps upward to sol (scale degree 5). Why would a musician trained in tonal conventions find this unusual?

• A. Because fa is a stable tone that doesn't need to move at all
• B. Because fa has a downward tendency toward mi — moving upward works against the expected gravitational pull
• C. Because leaps from scale degree 4 are forbidden in tonal voice-leading
• D. Because sol is less stable than fa, so the leap creates unnecessary tension

Answer: (B)

Fa (scale degree 4) is a tendency tone with a strong downward pull toward mi (scale degree 3), separated by just a half step. Moving fa upward to sol contradicts this gravitational tendency, which is why composers use such motion deliberately for expressive effect — it creates a sense of the melody 'fighting' against the tonal pull. Options A and C are wrong because fa is unstable and leaps are not forbidden. Option D is wrong because sol is part of the stable tonic triad.

Question 2

Why does ti (scale degree 7) create stronger resolution pressure than re (scale degree 2)?

• A. Ti is higher in the scale, and higher notes always carry more tension
• B. Ti is part of the dominant chord, which is always tense by definition
• C. Ti lies just a half step below do, making the distance to its resolution point extremely small
• D. Re has no stable neighbor to resolve toward, so it doesn't feel the pull

Answer: (C)

The strength of a tendency tone's pull is closely related to proximity — specifically, half-step distance. Ti sits just one semitone below do, making the pull toward resolution unusually strong. Re is a whole step from both do (below) and mi (above), so its tendency is much weaker. Option A is false — scale position alone doesn't determine tension. Option B conflates chord membership with tendency, and Option D is wrong because re does have tendencies, just weaker ones.

Question 3

Scale degree 5 (sol) is an unstable tone that tends to resolve downward to scale degree 4 (fa).

• T. True
• F. False

Answer: False

Sol is part of the tonic triad (do-mi-sol) and is one of the most stable scale degrees — it sounds nearly as settled as do itself. It has no strong tendency to move anywhere and can serve as a comfortable resting point in a melody. The unstable tendency tones are degrees 2, 4, 6, and especially 7. The statement reverses the logic: fa (4) tends to resolve DOWN to mi (3), not the other way around.

Question 4

The tendency of scale degree 7 (ti) to resolve upward to do is stronger in tonal music than in modal contexts.

• T. True
• F. False

Answer: True

The strong upward pull of ti depends on its role as the leading tone — a pitch just a half step below the tonic in major keys and harmonic minor. Modal scales (like Dorian or Mixolydian) often use a lowered seventh degree, which is a whole step below the tonic. Without the half-step proximity, the gravitational pull is much weaker. This is explicitly noted in the Common Misconceptions section: scale degree tendencies are context-dependent, and the leading-tone pull is specifically a feature of tonal (not modal) harmony.

Question 5

Why do musicians who have internalized scale degree tendencies follow harmonic progressions by ear more quickly than those who only know them theoretically?

Model answer: Because scale degree tendencies let the ear predict where melody and harmony are going before conscious analysis kicks in. When a melody lands on ti, a musician with internalized tendencies already 'leans' toward the anticipated resolution to do — the inner ear is tracking tonal logic automatically. This works because scale degrees telegraph harmonic function: ti signals dominant harmony, fa suggests subdominant or V7. Theoretical knowledge requires effortful analysis; internalized tendencies operate below conscious awareness, freeing attention for higher-level listening.

The key distinction is between declarative knowledge ('ti resolves up to do') and procedural, automatic hearing. Ear training builds the latter. The explainer makes this point directly: 'when you hear a note land on ti in a melody, something in your ear leans forward in anticipation of resolution.' This automatic tracking is why musicians who have practiced singing through tendency tones can follow complex harmonic progressions in real time — the scale degrees are already doing analytical work for them.
