The Chorale That Collapses and the Twenty Minutes That Do Nothing
You direct the 47-member wind ensemble at a comprehensive high school; it meets three days a week for 50 minutes and performs at a district festival in four weeks. The program is a grade 5 march, a slow chorale transcription, and a contemporary overture. Recordings you make of rehearsals show the same pattern: the chorale's middle section (mm. 37–56) loses pitch center and rhythmic alignment every time; the clarinet section's tuning drifts sharp in the last ten minutes; you spend the final 20 minutes of nearly every rehearsal running the march from the top with no measurable improvement; six percussionists sit idle for roughly 25 minutes; and three students arrive late twice a week because their bus from a magnet program arrives at 8:05 for an 8:00 downbeat. Students watch you only at entrances and stop counting during rests.
1. Diagnose why the chorale's middle section fails. What are the three most plausible causes, and what would you listen for in the next rehearsal to choose among them?

Three plausible causes
- Tuning drift from breath support and dynamic: in a slow, sustained section, students play under-supported, pitch sags, and the ensemble chases it. The tell is a downward drift that worsens toward the end of long notes.
- Rhythmic subdivision failure: the printed rhythms are simple, but students are counting in half notes and losing the eighth-note pulse. The tell is that it collapses at the same bar every time-a reading problem, not a listening problem.
- Balance and voicing: inner voices overplay, the third of the chord is buried, and the sonority reads as out of tune. The tell is that it improves the moment one section tacet.
What to listen for next rehearsal
- Record mm. 37–56 and check whether pitch drifts progressively (support) or is unstable from the first chord (voicing).
- Have the ensemble play the passage on a single pitch or against a metronome subdivision. If it holds, the problem is rhythmic.
- Build each chord bottom-up, one section at a time; note which entrance disturbs the sonority.
- Ask two students to sing their parts. If they cannot sing it, they cannot play it in tune.
Why not simply repeat it: repetition without a hypothesis teaches the ensemble to rehearse failure. Naming the cause first is what makes the next ten minutes productive.
2. Rewrite the 50-minute rehearsal frame for the next two weeks. Justify the sequence and time allocations, and state what you stop doing.

Two-week rehearsal frame (50 minutes)
- 0–5: enter, set up, warm-up on the chorale's hardest interval rather than a generic scale.
- 5–12: section tuning against a drone; clarinets tune last and re-check at minute 40, since their drift appears late.
- 12–22: chorale, slow and fragmented-mm. 37–56 only, built bottom-up, singing first.
- 22–32: march in eight-bar chunks, one stated goal per repetition, no top-to-bottom runs.
- 32–42: overture or rotating sectionals.
- 42–48: run one transition between pieces, not one whole piece.
- 48–50: state the next rehearsal's target aloud; students write one sentence in a log.
What I stop doing: the 20-minute top-to-bottom march runs. They consume 40% of rehearsal time for no measurable gain, and they train students to stop listening. I replace them with two eight-bar repetitions that each have a criterion.
Sequencing rationale: the hardest cognitive work goes early, when attention is highest; tuning is placed where the drift actually occurs; and the closing run is a transition, which is where most performance failures happen.
Evidence: the recorder stays on, and one 60-second clip goes to the class page each week, so students hear the same evidence I do rather than taking my word for it.
3. How do you put the idle percussionists and the late-arriving students to instructional use without lowering expectations?
Read the worked answer
Percussion: from idle to essential
The six percussionists are idle 25 minutes because the score asks for them only at climaxes and because I have effectively treated waiting as their job. Two fixes:
- Rotate a rhythm section into the chorale work: suspended cymbal, timpani, and bass drum reinforce the harmonic rhythm and give the section a listening task-match the ensemble's decay, not its attack.
- Give them a written analysis task during wind-only segments: mark form, cues, and their entrances on a score excerpt, then check it at minute 45. Idle hands are acceptable; idle attention is not.
Late arrivals (three students, 8:05 for an 8:00 downbeat)
- Move the highest-stakes whole-ensemble work to 8:10–8:40 for four weeks; use 8:00–8:10 for section warm-ups and individual practice that late students can join without disrupting the ensemble.
- Do not re-teach the first ten minutes for them, and do not penalize them for a district bus schedule they do not control. Write to the magnet program's coordinator requesting a 7:45 bus and document the request.
- Give the three a first-five checklist (warm-up, tuning note, log entry) so their entry is routine.
Principle: the fix belongs to the schedule and the rehearsal design, not to the students' compliance.
