Week 15 — Quiz (auto-graded) · Charts, Keys, and the Real World

Course: MUS 156 Music Theory I · Kenosis College
Instructor: Professor Hemsworth
Unit: Learning Unit 15 of 16 (Week 15) · two sessions per week
Objectives tested: SLO 8 (apply theory in performance) · SLO 4 · SLO 5
Points: 10 (10 × 1) · Group: Quizzes (lowest 2 of 14 dropped) · Due: the end of Week 15 — a day early this week · 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-15.json, which also holds this unit's 15 exam-pool items (idents k3lu15x01–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	Transposing for a singer — direction	SLO 8
2	Multiple choice	B♭ instruments — written from concert	SLO 8
3	Multiple choice	E♭ instruments — sounding from written	SLO 8
4	Multiple choice	F instruments — key of the part	SLO 8
5	Matching	The roadmap: D.C., D.S., Fine, To Coda	SLO 8
6	Multiple choice	Nashville numbers in a named key	SLO 5
7	True / False	Nashville numbers = Roman numerals in street clothes	SLO 5
8	Multiple choice	What a lead sheet contains	SLO 8
9	Multiple choice	Slash-chord realization (bass note)	SLO 4
10	Multiple choice	Transposition by key — the interval	SLO 8

No trick questions; every distractor targets a misconception named in the Week 15 outline (up-a-minor-third "fixes" a too-high song, the wrong written-vs-sounding direction, numbers always counted from C, D.C./D.S. interchangeable).

Questions, key, and feedback

Q1 (MC). At soundcheck your lead singer reports that tonight's ballad sits a whole step above her sweet spot. The right move is —

• A. shift the entire chart — tune and chords alike — down a major second ✅
• B. shift the entire chart up a major second so the key rings brighter
• C. lower only the vocal line a step and leave the band untouched
• D. keep the key and let her flip the top notes down an octave

Feedback: Too high means the whole chart travels down — melody and chords together, one shared interval.

Q2 (MC). You want your B♭ trumpet player to produce concert F4. Which note belongs on her part?

• A. F4
• B. E♭4
• C. G4 ✅
• D. F5

Feedback: Trumpet parts sit a major second above concert pitch: to hear F4, write G4.

Q3 (MC). An alto sax part displays written G5. Which pitch actually reaches the audience?

• A. B♭5
• B. B♭4 ✅
• C. E5
• D. G4

Feedback: The alto sax sounds a major sixth beneath its page: written G5 emerges as B♭4.

Q4 (MC). The rhythm section is grooving in concert F major. In which key is the F horn player's part written?

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

Feedback: Horn parts are written a perfect fifth above concert: concert F major becomes written C major.

Q5 (Matching). Pair each navigation mark with the instruction it gives.

Answer bank: restart from bar one · hunt backward for the sign and resume there · your stopping place on the later pass · the launch point for the jump to the tail

• D.C. → restart from bar one ✅
• D.S. → hunt backward for the sign and resume there ✅
• Fine → your stopping place on the later pass ✅
• To Coda → the launch point for the jump to the tail ✅

Feedback: D.C. to the top, D.S. to the sign, Fine to stop, To Coda to jump — the chart's four road signs.

Q6 (MC). The key is A major and the napkin chart says 1 · 4 · 6m · 5. You play —

• A. A · D · F♯ · E
• B. A · E · F♯m · D
• C. A · D · F♯m · E ✅
• D. D · G · Bm · A

Feedback: In A major the numbers 1, 4, 6m, 5 decode to A, D, F♯ minor, E.

Q7 (True/False). Nashville numbers and Roman numerals capture the same key-relative relationships — the number chart is that idea in session shorthand.

• True ✅
• False

Feedback: True — 1, 4, 5 and I, IV, V describe identical relationships; only the costume differs.

Q8 (MC). You pass out a lead sheet at rehearsal. What is actually printed on it?

• A. a single melody staff crowned with chord symbols, each musician building a part from it ✅
• B. notated parts for every instrument in the group
• C. chord letters alone, with the tune carried from memory
• D. a groove chart for the bass and drums only

Feedback: Melody plus chord symbols is the whole page — the lead sheet trusts players to realize the rest.

Q9 (MC). The chart calls for C/E. Which note belongs in the bass player's hands?

• A. C
• B. G
• C. either one — the player's call
• D. E ✅

Feedback: The letter after the slash names the bass note: C/E puts E on the bottom.

Q10 (MC). For the vocalist's sake, a chart drops from G major into E major. Each written note moves —

• A. down a major third
• B. down a minor third ✅
• C. up a minor third
• D. down a major second

Feedback: G down to E spans a minor third, and every note in the chart drops by exactly that distance.

Answer key (quick reference)

The table below lists each item's correct response.

Q	Answer
1	A
2	C
3	B
4	D
5	D.C. → restart from bar one · D.S. → hunt backward for the sign and resume there · Fine → your stopping place on the later pass · To Coda → the launch point for the jump to the tail
6	C
7	True
8	A
9	D
10	B

Quality gate (machine-checked): exactly one correct option per single-answer item; the multiple-choice key sequence A C B D C A D 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 k3lu15q01–k3lu15q10 in _build/banks/lu-15.json, each tagged with its ledger concept_ids and objective. The same bank holds k3lu15x01–k3lu15x15: fifteen exam-pool items on the same Week 15 concepts with fully different stems (zero text overlap — the leakage gate checks). The final draws from the pool, never from the live quiz.
