Week 10 — Quiz (auto-graded) · Seventh Chords

Course: MUS 156 Music Theory I · Kenosis College
Instructor: Professor Hemsworth
Unit: Learning Unit 10 of 16 (Week 10) · two sessions per week
Objectives tested: SLO 4 (spell and identify seventh chords in every quality and inversion, from notation and from chord symbols) · SLO 7 (name what you hear — here, name what a chart hands you)
Points: 10 (10 × 1) · Group: Quizzes (lowest 2 of 14 dropped) · Due: the end of Week 10 · online, 15-minute timer, 1 attempt, closed to AI.

This is the human-readable quiz with its vetted answer key and feedback. The import-ready QTI is rendered by the build system from _build/banks/lu-10.json, which also holds this unit's 15 exam-pool items (idents k3lu10x01–x15) — those test the same concepts with different stems, feed the final, and never appear on this quiz. Every item below is answerable from text alone; no images required.

Blueprint

The table below maps each item to its type, concept, and objective.

#	Type	Concept(s)	Objective
1	Multiple choice	Dominant seventh — spelling from the symbol	SLO 4
2	Multiple choice	Chord symbols — the plain-7 rule	SLO 4
3	Multiple choice	Minor seventh chord — spelling	SLO 4
4	Multiple choice	Half-diminished vs. fully diminished	SLO 4
5	True / False	Diatonic sevenths — the viiø7 rule	SLO 4
6	Multiple choice	Figures — third in the bass	SLO 4
7	Multiple choice	Slash chords — what the slash means	SLO 4
8	Multiple choice	Slash chords — which member is the bass	SLO 4
9	Multiple choice	Identify the quality from spelled notes	SLO 7
10	Matching	The five qualities — symbol ↔ recipe	SLO 4

No trick questions; every distractor targets a misconception named in the Week 10 outline (7-means-major-seventh, viio7-in-major, ø-and-°-as-fonts, slash-as-division, inversion-changes-identity).

Questions, key, and feedback

Q1 (MC). The chart reads D7. Under your hands go —

• A. D F♯ A C♯
• B. D F♯ A C ✅
• C. D F A C
• D. D F♯ A B

Feedback: Dominant-type symbol: the major triad D–F♯–A capped by the minor seventh C natural.

Q2 (MC). B♭7, F7, D♭7 — when a chord symbol shows the bare digit 7, the distance from root up to seventh is always —

• A. a minor seventh ✅
• B. a major seventh
• C. a diminished seventh
• D. whatever seventh the key signature would give

Feedback: The naked 7 means minor seventh in any key; a major seventh must be requested by name as maj7.

Q3 (MC). Write out the four notes of Gm7.

• A. G B D F
• B. G B♭ D F ✅
• C. G B♭ D♭ F
• D. G B♭ D F♯

Feedback: Minor triad G–B♭–D plus the minor seventh F — no leading tone anywhere in sight.

Q4 (MC). Em7♭5 and E°7 agree on E, G, and B♭; only the top note separates them. Which statement gets it right?

• A. both hold D — two symbols for one chord
• B. Em7♭5 holds D♭, while E°7 holds D
• C. Em7♭5 holds D, while E°7 holds D♭ ✅
• D. both hold D♭ — two symbols for one chord

Feedback: Half-diminished keeps the minor seventh D; fully diminished squeezes it down to D♭ — one half step apart.

Q5 (True/False). Build a seventh chord on the leading tone of E♭ major without leaving the key: the chord you get is a fully diminished seventh.

• True
• False ✅

Feedback: Inside any major key, ^7 carries viiø7 — half-diminished; the fully diminished version needs harmonic minor.

Q6 (MC). A seventh chord sounds with its chordal third as the lowest voice. Write the figure —

• A. 7
• B. 4/2
• C. 6/5 ✅
• D. 4/3

Feedback: First inversion of a seventh chord takes 6/5 — the six and the five measured up from that bass third.

Q7 (MC). On a slide the symbol G/B appears. The letter after the slash instructs you to —

• A. swap between G and B chords, one each measure
• B. treat the key as having moved to B
• C. sound only the two pitches G and B
• D. voice a G major triad with B underneath ✅

Feedback: Left of the slash names the chord, right of it names the bass: G major over its own third, B.

Q8 (MC). C7/G asks for which member of the chord in the bass?

• A. the fifth ✅
• B. the root
• C. the seventh
• D. the third

Feedback: Inside C7, the note G serves as the fifth — a slash bass is identified by its role, not just its letter.

Q9 (MC). Four notes on the staff: G, B, D, F♯. The symbol that names the stack is —

• A. G7
• B. Gmaj7 ✅
• C. Gm7
• D. Gm7♭5

Feedback: F♯ sits a major seventh above G over a major triad — that combination is what maj7 promises.

Q10 (Matching). Connect each symbol on A with the construction it stands for.

Answer bank: a major triad capped by a major seventh · a major triad capped by a minor seventh · a minor triad capped by a minor seventh · a diminished triad capped by a minor seventh · a diminished triad capped by a diminished seventh

• Amaj7 → a major triad capped by a major seventh ✅
• A7 → a major triad capped by a minor seventh ✅
• Am7 → a minor triad capped by a minor seventh ✅
• Am7♭5 → a diminished triad capped by a minor seventh ✅
• A°7 → a diminished triad capped by a diminished seventh ✅

Feedback: Five spellings, one root: the triad and the seventh each choose their own quality.

Answer key (quick reference)

The table below lists each item's correct response.

Q	Answer
1	B
2	A
3	B
4	C
5	False
6	C
7	D
8	A
9	B
10	Amaj7 → a major triad capped by a major seventh · A7 → a major triad capped by a minor seventh · Am7 → a minor triad capped by a minor seventh · Am7♭5 → a diminished triad capped by a minor seventh · A°7 → a diminished triad capped by a diminished seventh

Quality gate (machine-checked): exactly one correct option per single-answer item; the multiple-choice key sequence B A B C C D A B carries no run longer than two and no positional lean; option lengths balanced within each item; every spelling claim verified against the course theory reference by the correctness gate; no item tests material from a later unit; no stem or scenario reuses the tutorial, practice, chapter, studio, assignment, or exam-pool surfaces (leakage-checked mechanically at build time).

Item-bank note (instructor-facing)

The ten quiz items above carry idents k3lu10q01–k3lu10q10 in _build/banks/lu-10.json, each tagged with its ledger concept_ids and objective. The same bank holds k3lu10x01–k3lu10x15: fifteen exam-pool items on the same fourteen Week 10 concepts with fully different stems (zero text overlap — the leakage gate checks). The final draws from the pool, never from the live quiz.
