Week 3 — Quiz (auto-graded) · Dividing the Beat

Course: MUS 156 Music Theory I · Kenosis College
Instructor: Professor Hemsworth
Unit: Learning Unit 3 of 16 (Week 3) · two sessions per week
Objectives tested: SLO 1 (read and notate meter and beat division) · SLO 7 (name what you hear — here, name the split you can feel)
Points: 10 (10 × 1) · Group: Quizzes (lowest 2 of 14 dropped) · Due: the end of Week 3 · 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-03.json, which also holds this unit's 15 exam-pool items (idents k3lu03x01–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	Compound division defined	SLO 1
2	Multiple choice	6/8 classification	SLO 1
3	Multiple choice	Beats = top ÷ 3 (9/8)	SLO 1
4	Multiple choice	The dotted beat unit (12/8)	SLO 1
5	Matching	Meters → classifications	SLO 1
6	Multiple choice	Compound division counting	SLO 7
7	Multiple choice	Compound subdivision counting	SLO 7
8	Multiple choice	Triplet duration	SLO 1
9	True / False	6/8 ≠ 3/4	SLO 7
10	Multiple choice	Syncopation	SLO 7

No trick questions; every distractor targets a misconception named in the Week 3 outline (top-number-equals-beats, eighth-note-gets-the-beat, 6/8-equals-3/4, triplets-speed-up, six-counting at tempo).

Questions, key, and feedback

Q1 (MC). Inside a compound meter, every beat behaves how?

• A. the bar always carries three beats exactly
• B. the tempo runs quicker than in simple meters
• C. it splits into three equal parts instead of two ✅
• D. every note in the bar wears a dot

Feedback: Compound is about the beat's interior, not its speed: each beat opens into three even divisions.

Q2 (MC). In the meter families, 12/8 belongs under —

• A. compound quadruple ✅
• B. compound duple
• C. simple quadruple
• D. compound triple

Feedback: Twelve eighths bundle into four dotted-quarter beats of three eighths each — four beats dividing in three.

Q3 (MC). One bar of 6/8 contains how many felt beats?

• A. six
• B. two ✅
• C. three
• D. four

Feedback: Divide the top number by three in compound signatures: 6/8 is two dotted-quarter beats, not six little ones.

Q4 (MC). The felt beat of 6/8 is carried by which value?

• A. the eighth note
• B. the plain, undotted quarter note
• C. the dotted eighth note
• D. the dotted quarter note ✅

Feedback: Three eighths bundle into one felt beat, and three eighths of time equal a dotted quarter — compound meters put a dotted note on the beat.

Q5 (Matching). Match every signature below to its family label.

Answer bank: compound triple · compound quadruple · compound duple · simple quadruple · simple duple

• 9/8 → compound triple ✅
• 12/8 → compound quadruple ✅
• 6/8 → compound duple ✅
• 4/4 → simple quadruple ✅
• 2/4 → simple duple ✅

Feedback: For 6, 9, or 12 over 8, divide the top by three to find the beat count; smaller top numbers name the beat count directly.

Q6 (MC). Rolling through a 12/8 bar, the third beat and its division are spoken —

• A. 3 e & a
• B. 3 la li ✅
• C. 3 & a
• D. 3 ta la

Feedback: Compound beats speak their number and then la-li for the two remaining divisions — the e-&-a set stays in simple meter.

Q7 (MC). One compound beat — the second of the bar — is carved into six sixteenths. You speak it —

• A. 2 e & a
• B. 2 ta li ta la ta
• C. 2 & a
• D. 2 ta la ta li ta ✅

Feedback: Compound subdivision interleaves ta between the division syllables: number, ta, la, ta, li, ta.

Q8 (MC). In 3/4, a fiddler tucks an eighth-note triplet into beat 2. How much time does that three-note group claim?

• A. exactly one beat — the space two plain eighths would fill ✅
• B. a beat and a half, since the extra note stretches it
• C. a shade under one beat, because triplets compress
• D. as much time as the fiddler fancies

Feedback: A triplet borrows the exact duration of two ordinary notes of its kind and splits that time three ways.

Q9 (True/False). A waltz bar of 3/4 and a jig bar of 6/8 hold identical total time, so a performer may treat the two meters as interchangeable.

• True
• False ✅

Feedback: Equal totals, opposite groupings: 3/4 pulses three-times-two, 6/8 pulses two-times-three — the accent pattern is the meter.

Q10 (MC). In a reggae-flavored groove, the guitar skips every numbered beat and chops only on the off-beat halves. That deliberate off-beat emphasis is —

• A. an anacrusis
• B. swing feel
• C. syncopation ✅
• D. compound division

Feedback: Syncopation shifts weight onto moments the meter marks as weak — attacks between the beats while the beats go silent.

Answer key (quick reference)

The table below lists each item's correct response.

Q	Answer
1	C
2	A
3	B
4	D
5	9/8 → compound triple · 12/8 → compound quadruple · 6/8 → compound duple · 4/4 → simple quadruple · 2/4 → simple duple
6	B
7	D
8	A
9	False
10	C

Quality gate (machine-checked): exactly one correct option per single-answer item; the multiple-choice key sequence C A B D B D A C 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 k3lu03q01–k3lu03q10 in _build/banks/lu-03.json, each tagged with its ledger concept_ids and objective. The same bank holds k3lu03x01–k3lu03x15: fifteen exam-pool items on the same eight Week 3 concepts with fully different stems (zero text overlap — the leakage gate checks). The midterm draws from the pool, never from the live quiz.
