Delay a Complete Movement Motif

Supplied materials

• Paper and a pencil, typed notes or a browser scratch area. Color names can replace colored supplies; drawn figures and timelines can replace performance.
• Complete teaching inputs: A safe drawn gesture motif lasts 3 counts. PartB repeats partA’s order starting 1 count later. Which schedule is a canon under that brief? Supplied candidates: (A) B starts at count-time 1 and finishes at 4 (B) B starts at 0 and finishes at 3 (C) B starts at 1 and reverses every event (D) B starts at 1 but omits the last event.
• Independent check: A safe drawn gesture motif lasts 4 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 6 (B) B starts at 0 and finishes at 4 (C) B starts at 2 and reverses every event (D) B starts at 2 but omits the last event.

Learn the idea

Inspect the relationships underlying a score. Group eighth-note subdivisions, construct the supplied major-scale pattern, apply a declared tonal return and schedule a delayed movement motif with complete duration accounting. A movement canon schedules a repeated motif after a stated delay. Preserve the motif’s ordered events and full duration while shifting the second line’s starting time.

Reason through the supplied case: An exact delayed imitation retains the motif’s event order and duration. Starting at 1 shifts its end to 1+3=4. A mirror, reversal or shortened phrase is a different transformation; diagrams can represent both parts without physical travel.

A paper timeline or small seated hand score can complete the plan. No running, balancing or full-body repetition is required, and text checks do not verify synchronized execution.

1. Read the complete teaching inputs and mark the feature, rule or constraint being tested.
2. Compare the model decision with one rejected candidate; state the visible evidence or calculation that distinguishes them.
3. Solve the independent check and the three changed-input practice cases before reading feedback.
4. Score a four-count drawn hand motif at time zero and a complete repeat beginning at time two.
5. Check your artifact against these explicit criteria: The second motif retains all four counts in order and ends at time six.

Take it further

New-input analysis: 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. Expected relationship: 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. Create your own artifact: Score a four-count drawn hand motif at time zero and a complete repeat beginning at time two. Completion criteria: The second motif retains all four counts in order and ends at time six.
