Study guide: Dotted Values, Pitch Distance, Retrograde, and Objectives
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.
Ideas to explain in your own words
- In the supplied Western notation model, one dot adds half the undotted note’s duration. Calculate the base plus its half in the stated quarter-note beat unit. The calculation depends on the given beat unit and a single dot. It does not measure actual performed length, and other notation conventions require their stated context.
- Supplied equal-step pitch numbers rise by one semitone per unit. Subtract the lower position from the higher to calculate their distance without confusing it with letter spelling. The numeric model describes pitch distance. It does not by itself identify a written interval’s generic number or quality, which also depend on note-letter spelling.
- 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. 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.
- An objective names what a fictional character wants. A playable action is something the character can do toward that objective while confronting the supplied obstacle. An emotion label alone does not specify an action. Keep the response grounded in the fictional scene; planning or reading it does not verify an acted performance.

A worked review example
Add Half the Base Duration: In this Western-duration model, one dot adds half the original duration. A note lasts 4 quarter-note beat units before its dot. What is its dotted duration? Supplied candidates: (A) 2 beats (B) 4 beats (C) 6 beats (D) 8 beats. Model reasoning: The added duration is half of 4, or 2. Base plus addition gives 4+2=6 quarter-note beat units. The base-only choice omits the dot, doubled duration adds too much, and dot-only duration omits the original note. This checks written duration, not performed timing. Subtract Ordered Pitch Positions: In a supplied twelve-equal-step pitch-number model, pitches are 48 and 50; one number step is one semitone. What is the upward distance? Supplied candidates: (A) 1 semitone (B) 2 semitones (C) 3 semitones (D) 4 semitones. Model reasoning: The interval distance is the pitch-number difference: 50−48=2 semitones. This chromatic distance differs from a generic letter-name interval and says nothing about the performer’s loudness or instrument. Reverse a Motif’s Event Order: 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. Model reasoning: 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. Choose an Action from Want and Obstacle: Original scene: a character wants to borrow a pencil, but the other character is busy. Which playable action directly addresses both objective and obstacle? Supplied candidates: (A) Ask for a pencil and offer to return it after the task (B) Claim the character has no goal (C) Ignore both the need and obstacle (D) Specify only a costume color with no action. Model reasoning: The proposed action moves toward borrow a pencil while responding to the obstacle that the other character is busy. A playable action can be represented in speech, gesture or a written scene; an emotion label or costume choice alone does not define what the character does.
Make a practice plan
- Inspect the supplied descriptions, notation or timeline before making an interpretation.
- Solve each independent case, then explain the specific evidence behind a correction.
- Produce the original paper/text artifacts and retain one criterion-based revision.
- Attempt the unit review and exam with their new inputs; performance remains optional and separately observed.
