Score Conventions Before the First Rehearsal
A student conductor is preparing a 3-minute arrangement of a pop song for a school ensemble: 6 Bb clarinets, 4 horns in F, 3 trumpets, 2 trombones, piano, bass guitar, drum kit, and 3 singers. The score is handwritten in concert pitch throughout, with no transposed parts. Rehearsal marks appear only at the start and at bar 48; bar numbers are missing from the horn parts. A clarinet part has a concert G below the staff written as a ledger-line A, which the player reads as A natural; a horn part changes from bass to treble clef with no warning. Page turns fall two bars before the final chorus in the piano and trombone parts. The first rehearsal is in five days. The student conductor has 90 minutes of rehearsal and a 10-minute run-through slot. The teacher must decide which score conventions to fix first and what to tell the players, given limited copying time.
1. Prioritise the score corrections. Explain which errors would most likely cause a rehearsal breakdown and which can be managed verbally.

Fix first the errors that cause wrong notes at the first read: the clarinet ledger-line pitch and the unnotated clef change in the horn part. A concert G below the staff is not the same as a written A; if the player reads A natural, the chord will be wrong. The clef change without warning will cause a wrong octave. Second priority: page turns before the final chorus in piano and trombone; a bad turn can derail the ending, so re-copy those two parts or agree a two-bar rest. Third: add bar numbers and rehearsal marks, because the conductor can call 'bar 48' but the horns cannot find it. Transposed parts are important, but with five days left, verbal instructions plus a correct pitch list may be more realistic than recopying all parts. The teacher should distinguish 'must fix' from 'can manage verbally'.
2. Explain the transposition decisions needed for the Bb clarinet and horn in F parts, using the specific pitches mentioned.

Bb clarinet sounds a major 2nd lower than written, so to sound concert G below the staff the written note must be a major 2nd higher: A below the staff (or the equivalent ledger-line A). The part as described is written in concert pitch but the player reads it as written, producing A natural; that is the error. The horn in F sounds a perfect 5th lower than written, so a concert pitch must be written a perfect 5th higher. For the clef change, write the new clef at least one bar before the entry and add a cautionary note name or an octave sign. If the score remains in concert pitch, label it 'concert pitch score-not for players' and provide transposed parts or a pitch guide. Do not ask players to transpose at sight in the first rehearsal.
3. Propose a rehearsal plan for the 90 minutes that accounts for the remaining score problems.

90-minute plan: 10 minutes tuning and reading the corrected pitch list; 15 minutes on the final chorus only, with piano and trombone practising the page turn and the conductor giving a clear upbeat; 20 minutes on the clarinet and horn entries that were wrong, slowly, then in context; 15 minutes on the two rehearsal-mark sections, using bar numbers; 20 minutes full run with stops only for structural errors; 10 minutes run the ending twice. Keep the 10-minute run-through slot for a complete performance, not notes. The plan prioritises the ending and the wrong-note entries because those are the highest-risk failures. Do not spend the first rehearsal copying parts; assign that before rehearsal.
