Week 4 — Quiz (auto-graded) · Major

Course: MUS 156 Music Theory I · Kenosis College
Instructor: Professor Hemsworth
Unit: Learning Unit 4 of 16 (Week 4) · two sessions per week
Objectives tested: SLO 2 (keys, scales, signatures, the circle) · SLO 7 (name what you hear — here, name what you can build)
Points: 10 (10 × 1) · Group: Quizzes (lowest 2 of 14 dropped) · Due: the end of Week 4 · 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-04.json, which also holds this unit's 15 exam-pool items (idents k3lu04x01–x15) — those test the same concepts with different stems, feed the midterm, 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	The W W H W W W H pattern	SLO 2
2	Multiple choice	Spelling a sharp-side scale (D major)	SLO 2
3	Multiple choice	The spelling law (every letter once)	SLO 7
4	Multiple choice	Order of sharps	SLO 2
5	Multiple choice	Writing a flat signature (A♭ major)	SLO 2
6	Multiple choice	Key from signature (sharp side)	SLO 2
7	Multiple choice	Circle of fifths, flat direction	SLO 2
8	True / False	Enharmonic keys ≠ the same key	SLO 7
9	Multiple choice	Scale degrees ^1–^7	SLO 2
10	Matching	Movable-do solfège	SLO 7

No trick questions; every distractor targets a misconception named in the Week 4 outline (accidentals-are-random, scrambled orders, the F♯-equals-G♭ collapse, first-sharp-instead-of-last, signature-tells-the-first-note).

Questions, key, and feedback

Q1 (MC). Between which degree pairs does a major scale tuck its two half steps?

• A. ^1–^2 and ^5–^6
• B. ^3–^4 and ^6–^7
• C. ^2–^3 and ^7–^8
• D. ^3–^4 and ^7–^8 ✅

Feedback: W-W-H-W-W-W-H: the pattern narrows only from mi to fa and from ti back home to do.

Q2 (MC). Written out in full from E3, the E major scale reads —

• A. E3 F♯3 G♯3 A3 B3 C♯4 D4 E4
• B. E3 F♯3 G♯3 A3 B3 C♯4 D♯4 E4 ✅
• C. E3 G♭3 G♯3 A3 B3 C♯4 D♯4 E4
• D. E3 F♯3 G♯3 A♯3 B3 C♯4 D♯4 E4

Feedback: Lay the whole-and-half-step pattern on E and four sharps appear: F♯, G♯, C♯, and D♯.

Q3 (MC). A classmate proposes the scale A3 B3 C♯4 D4 E4 F♯4 A♭4 A4. Without touching a keyboard, you can toss it out because —

• A. scales built on A can never include flats
• B. an ascending scale may not restate its opening letter at the top
• C. one letter shows up twice while a different letter is skipped ✅
• D. every major scale is required to start from a white key

Feedback: Scale spelling walks the alphabet once per letter — writing A♭ where G♯ belongs doubles one letter and orphans another.

Q4 (MC). When a signature finally holds all seven sharps, which sharp was the last one added?

• A. B♯ ✅
• B. F♯
• C. E♯
• D. A♯

Feedback: Sharps enter as F-C-G-D-A-E-B, so B♯ is the seventh and final arrival, completing C♯ major.

Q5 (MC). The signature of D♭ major displays —

• A. B♭, E♭, A♭, D♭, and G♭ — five flats ✅
• B. B♭, E♭, A♭, and D♭ — four flats
• C. F♯, C♯, G♯, D♯, and A♯ — five sharps
• D. A♭, D♭, G♭, C♭, and F♭ — five flats

Feedback: D♭ major spends the first five flats of the order, its signature closing on G♭.

Q6 (MC). A signature of exactly two flats belongs to which major key?

• A. E♭ major
• B. F major
• C. B♭ major ✅
• D. D major

Feedback: Two flats — B♭ and E♭ — mark B♭ major; a handy shortcut is that the next-to-last flat names the key.

Q7 (MC). From A major, take one step in the flat direction around the circle of fifths. You land on —

• A. E major
• B. D major ✅
• C. G major
• D. B♭ major

Feedback: Flatward travel strips one sharp per stop: A major's three sharps thin to D major's two.

Q8 (True/False). C♯ major and D♭ major are merely two printings of a single key.

• True
• False ✅

Feedback: They share every sound and not one spelling — seven sharps versus five flats make them distinct written keys.

Q9 (MC). Inside D major, scale degree ^6 is the note —

• A. A
• B. G
• C. C♯
• D. B ✅

Feedback: Count up from the tonic D: E is ^2, F♯ ^3, G ^4, A ^5, and B sits sixth.

Q10 (Matching). Give each scale degree its movable-do syllable.

Answer bank: fa · la · re · ti · mi · do · sol

• ^4 → fa ✅
• ^6 → la ✅
• ^2 → re ✅
• ^7 → ti ✅
• ^3 → mi ✅

Feedback: Movable do pins do to the tonic of the moment; the ladder above it always runs re-mi-fa-sol-la-ti.

10	^4 → fa · ^6 → la · ^2 → re · ^7 → ti · ^3 → mi

Quality gate (machine-checked): exactly one correct option per single-answer item; the multiple-choice key sequence D B C A A C B D 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 k3lu04q01–k3lu04q10 in _build/banks/lu-04.json, each tagged with its ledger concept_ids and objective. The same bank holds k3lu04x01–k3lu04x15: fifteen exam-pool items on the same Week 4 concepts with fully different stems (zero text overlap — the leakage gate checks). The midterm draws from the pool, never from the live quiz.
