The Ensemble Balance Decision
A school chamber ensemble of six players (two violins, viola, cello, flute and clarinet) is preparing a 12-minute program for an assessment. In rehearsal, the clarinet's chalumeau register is inaudible beneath the two violins in the second movement, where all parts are marked mezzo-forte. The clarinettist responds by playing louder, which makes the tone spread and the intonation sharp. The flautist, whose part doubles the first violin an octave higher in the same passage, is also pushing. The cellist has begun playing more softly to compensate, and the ensemble's tempo has drifted slower over successive run-throughs. The assessment criteria include balance, blend, intonation and stylistic coherence. The performance is in ten days and there are three rehearsals left.
1. Identify the root cause of the balance problem and recommend how the ensemble should address it.

The root cause is not insufficient clarinet volume but an orchestration and dynamic-planning problem: the passage is marked uniformly mezzo-forte, so the accompaniment figures in the violins and the octave doubling in the flute sit at the same dynamic level as the clarinet's weakest register. Asking the clarinettist to play louder treats the symptom, and it produces the predictable side effects the ensemble is already hearing: a spread tone, sharp intonation, and a compensatory softening by the cello that further destabilises the bass.
The ensemble should rebalance by reducing the accompanying parts, not by raising the melody. The violins should play the passage at mezzo-piano with lighter bowing, the flute should either drop out of the doubling or reduce to piano, and the cello should return to the written dynamic so the bass remains firm. The clarinettist should then be able to play at mezzo-forte with a supported, focused tone. The ensemble should also agree on a hierarchy for the passage (melody, countermelody, accompaniment) and rehearse it slowly with that hierarchy stated aloud before restoring tempo.
2. Explain the connection between the balance fix and the tempo drift, and propose a rehearsal plan for the three remaining sessions.

The tempo drift is likely a consequence of the balance problem: when players cannot hear themselves or the melody, they slow down to listen harder and to coordinate, and the cellist's reduced dynamic removes the rhythmic anchor. Fixing the balance should reduce the drift, but the ensemble also needs to rehearse with a clear pulse source and a conductor cue at the passage entry so that tempo is not renegotiated every run-through.
Plan: rehearsal one, slow rehearsal of the second movement with the new dynamic hierarchy and no tempo goal, plus a recorded run-through for the ensemble to hear the balance objectively. Rehearsal two, restore tempo with a metronome for the first few repetitions, then without it, and check intonation on sustained chords. Rehearsal three, full run-through of the 12-minute program with the balance decisions locked, followed by a recording and a short self-assessment against the four criteria. This sequence fixes the cause first, then stabilises tempo, then integrates, which fits the ten-day window.
