The Modulation the Rubric Didn't Anticipate
Ms. Okafor's 11th-grade composition class has a summative task with a published rubric: 24 measures, functional tonal harmony in a major key, two phrases with a clear cadence, and a written analysis of the harmonic choices. One student, Devin, submits a 26-measure piece in D major that, at measure 13, moves to B minor through a pivot on F-sharp and stays there for eight measures before returning to D. He also uses a bVII chord (C major) in measure 6, which the rubric's harmony strand does not mention. Devin's written analysis explains the modulation as depicting a loss of certainty. The rubric awards points for harmonic consistency and a clear major-key tonal center. Colleagues disagree: one says mark the harmony strand down; the other says the piece exceeds the standard.
1. Identify the conflict in the rubric's wording and recommend how to score Devin's harmony strand. Justify your reading.

The conflict is between a scope statement and a ceiling. The phrase “functional tonal harmony in a major key” sets a floor: the piece must use functional harmony and establish a major tonic. It never says “no modulation” or “no mode mixture,” and neither does the “harmonic consistency” descriptor. So the question is not whether Devin broke a rule but whether the written descriptors, read literally, describe his piece.
- The modulation is prepared by a pivot and the return to D is cadenced. That is ordinary tonal practice, not a departure from it.
- bVII is a borrowed chord with a defensible function and does not weaken the tonic.
- The only measurable risk is proportion: eight of 26 bars sit in B minor. But “clear major-key tonal center” concerns audibility of the tonic, not bar counts.
Score the strand at full credit and attach a written rationale. If the department intended a stricter ceiling, the rubric was the defect. Fix it prospectively; do not apply an unwritten rule retroactively to a student who followed the document he was given.
2. Devin asks how to revise so the piece cannot be misread as failing the rubric. Propose a revision and analyze the cost.

Two defensible options, with different costs:
Option A, tonicize rather than modulate. Keep the F-sharp pivot but replace the confirming cadence in B minor with a half cadence, so the passage functions as an extended tonicization of the relative minor. The expressive “loss of certainty” survives because the harmony still destabilizes; the piece never claims a second tonic. Cost: the eight-bar section now needs a different bass line and the climax lands earlier than Devin wants.
Option B, keep the piece, add a rubric-alignment note. Devin submits a short paragraph mapping each harmonic event to the descriptors. Cost: none musically, but it rewards compliance writing and may not satisfy a grader who reads the rubric as a ceiling.
Advise against simply shortening the B-minor section to four bars. That is a proportional fix to a problem that is really about wording, and it teaches the student that the way to pass a rubric is to shrink his ideas. The larger lesson is that rubrics are texts to be read closely, not rules to be gamed.
3. Devin's analysis advances an interpretive claim the rubric does not request. How should the analysis strand be scored, and what is the risk in either direction?

Score the analysis on its stated criteria: correct identification of harmonic events and sound justification of choices. Devin's labels are accurate - the pivot is an F-sharp chord functioning in both keys, and C major is a bVII borrowed from the parallel minor. He loses nothing on accuracy.
Risk of rewarding the narrative: if rhetorical polish substitutes for analysis, students learn that a moving story covers a mislabeled chord. Do not add points for “loss of certainty.”
Risk of penalizing it: a student is punished for exceeding the task, which is the opposite of what a composition class should signal.
The defensible move is a comment that separates the two: full credit on the harmonic labels, plus a note that the interpretive layer is welcome but unscored. If the department wants to credit interpretation, add a fourth strand next term with its own descriptors so the expectation is public before students write. Changing what counts after submission is the fairness problem, not the interpretation itself.
