Reverse a Motif’s Event Order

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: An original safe movement motif is point → circle → pause. Its retrograde reverses event order, retaining each event. Which score is the retrograde? Supplied candidates: (A) circle → pause → point (B) pause → circle → point (C) point → circle → pause (D) point → circle → pause → repeat.
• Independent check: An original safe movement motif is reach → pause → lower. Its retrograde reverses event order, retaining each event. Which score is the retrograde? Supplied candidates: (A) lower → pause → reach (B) pause → lower → reach (C) reach → pause → lower (D) reach → pause → lower → repeat.

Learn the idea

Move from labels to transformations and reasons. Calculate dotted durations, compare semitone positions, reverse an ordered movement motif and connect a fictional character’s goal and obstacle to a playable action. Retrograde reverses the order of the stated events. Keep each event itself intact while moving the final one first and the initial one last in the new score.

Reason through the supplied case: Reverse the three positions: last becomes first, middle stays middle, and first becomes last. The resulting motif is pause → circle → point. It can be represented with drawings or small comfortable hand gestures; retrograde does not require risky backward travel.

Reversal differs from mirroring a gesture’s direction or making it faster. Represent the events with paper arrows or small comfortable hand gestures rather than large physical movements.

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 three distinct small hand shapes, then place the exact three events in reverse order beneath them.
5. Check your artifact against these explicit criteria: Every original event occurs once in each score, and the second score reverses their positions.

Take it further

New-input analysis: An original safe movement motif is near → far → hold. Its retrograde reverses event order, retaining each event. Which score is the retrograde? Supplied candidates: (A) far → hold → near (B) hold → far → near (C) near → far → hold (D) near → far → hold → repeat. Expected relationship: hold → far → near. Reverse the three positions: last becomes first, middle stays middle, and first becomes last. The resulting motif is hold → far → near. It can be represented with drawings or small comfortable hand gestures; retrograde does not require risky backward travel. Create your own artifact: Score three distinct small hand shapes, then place the exact three events in reverse order beneath them. Completion criteria: Every original event occurs once in each score, and the second score reverses their positions.
