Unit review questions
1. This conventional compound-meter plan has 2 complete bars of 12/8, with eighth-note subdivisions grouped in threes. How many dotted-quarter beats fill the whole plan?
Need a hint?
  • In the supplied compound meters, eighth-note subdivisions group in threes.
  • The exercise explicitly uses the conventional compound grouping.
2. Supplied major-scale semitone pattern from root 53 has offsets 0,2,4,5,7,9,11,12. Fill the missing pitch-number in [53, 55, 57, 58, '?', 62, 64, 65].
Need a hint?
  • The supplied Western major-scale pattern uses semitone offsets zero, two, four, five, seven, nine, eleven and twelve from the tonic.
  • Numeric pitch construction does not automatically determine correct letter spelling or a performed scale.
3. In a supplied tonal phrase, A is the named tonic and E the dominant. The brief asks to end on its tonic after dominant tension. Which final pair follows that plan?
Need a hint?
  • A supplied tonal brief can name a dominant tension and require a final return to its declared tonic.
  • This is a particular Western tonal exercise, not a universal musical requirement.
4. A safe drawn gesture motif lasts 4 counts. PartB repeats partA’s order starting 3 counts later. Which schedule is a canon under that brief?
Need a hint?
  • A movement canon schedules a repeated motif after a stated delay.
  • A paper timeline or small seated hand score can complete the plan.

Use the skills in a new task

Complete this four-part arts evidence sheet. 1. This conventional compound-meter plan has 3 complete bars of 9/8, with eighth-note subdivisions grouped in threes. How many dotted-quarter beats fill the whole plan? Supplied candidates: (A) 10 beats (B) 11 beats (C) 8 beats (D) 9 beats. Then Draw a nine-eighth-note bar grouped into three sets of three, and label its dotted-quarter beat groups. Criteria: All nine subdivisions remain present and the bar contains three stated compound beats. 2. Supplied major-scale semitone pattern from root 55 has offsets 0,2,4,5,7,9,11,12. Fill the missing pitch-number in [55, 57, 59, 60, 62, 64, '?', 67]. Supplied candidates: (A) 65 pitch-number (B) 66 pitch-number (C) 67 pitch-number (D) 68 pitch-number. Then Build a numeric major scale from root sixty and annotate the two one-semitone neighboring gaps. Criteria: The offsets are applied consistently, and the gaps between degrees three/four and seven/eight are one semitone. 3. In a supplied tonal phrase, B-flat is the declared tonic and F its dominant. The brief requires a final dominant-to-tonic return. Which final pair follows that stated plan? Supplied candidates: (A) B-flat → B-flat (B) B-flat → F (C) F → B-flat (D) F → F. Then Write a three-section tonal map opening on a named tonic, moving to its supplied dominant and returning to the tonic. Criteria: The opening and final tonic agree, and the middle section is the declared dominant rather than a substituted unrelated label. 4. A safe drawn gesture motif lasts 6 counts. PartB repeats partA’s order starting 2 counts later. Which schedule is a canon under that brief? Supplied candidates: (A) B starts at count-time 2 and finishes at 8 (B) B starts at 0 and finishes at 6 (C) B starts at 2 and reverses every event (D) B starts at 2 but omits the last event. Then Score a four-count drawn hand motif at time zero and a complete repeat beginning at time two. Criteria: The second motif retains all four counts in order and ends at time six.

Work on paper or in your own document. Explain the choices you made.

  • Answer each supplied changed-input analysis with its visible evidence, rule or calculation.
  • Include the original artifact required for each lesson; paper/text equivalents are acceptable.
  • Apply the stated criteria and document one concrete revision.
  • Describe planning/analysis accurately; do not claim unobserved musical, acting or dance execution.
Compare with a model response

1. 9 beats. Each bar contains 9 eighth-note subdivisions grouped into 3 dotted-quarter beats. Across 3 complete bars, 3×3=9 beats are required. The grouping convention and complete-bar assumption are supplied; other accent plans need their own interpretation. An original artifact is acceptable when All nine subdivisions remain present and the bar contains three stated compound beats. 2. 66 pitch-number. The missing position uses offset 11 from the supplied pattern. Add it to root 55 to obtain 66. This models one Western major scale; other traditions can organize pitch differently. An original artifact is acceptable when The offsets are applied consistently, and the gaps between degrees three/four and seven/eight are one semitone. 3. F → B-flat. The declared relationship requires the dominant F before tonic B-flat. F→B-flat therefore completes this particular written brief. Another ending could serve a different artistic plan, but harmonic labels alone do not establish perceived or performed resolution. An original artifact is acceptable when The opening and final tonic agree, and the middle section is the declared dominant rather than a substituted unrelated label. 4. B starts at count-time 2 and finishes at 8. An exact delayed imitation retains the motif’s event order and duration. Starting at 2 shifts its end to 2+6=8. A mirror, reversal or shortened phrase is a different transformation; diagrams can represent both parts without physical travel. An original artifact is acceptable when The second motif retains all four counts in order and ends at time six.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
