Adapting a Student Composition for an Intermediate Ensemble
Kiri is music director of a 24-player intermediate school ensemble. A Year 12 composer, Jonah, has written a five-minute work, Tidal, for full symphonic band, but the ensemble has only two flutes, one clarinet, three saxophones, two trumpets, one trombone, piano, bass guitar and drum kit. The score is in 4/4 at crotchet = 132, with a 7/8 bar at rehearsal mark F and a 5/4 bar at H. Jonah's MIDI demo runs at 144, and he says the piece must feel 'urgent'. The brass parts go up to written high C for trumpet and F above middle C for trombone; the clarinet has a long altissimo passage. There is one 100-minute rehearsal before a concert, and the programme also includes two other works. Jonah is resistant to cuts and wants the original metre changes kept. Kiri must decide what to adapt, what to rehearse first, and how to explain fidelity to Jonah.
1. What should Kiri adapt in Jonah's score, and what must she preserve?
Read the worked answer
Kiri should preserve the piece's identity markers: the 7/8 bar at F, the 5/4 bar at H, the driving quaver pulse, and the harmonic shape of the main theme. She can adapt orchestration and difficulty without erasing those features. The trumpet high C and trombone F above middle C should be redistributed to saxophones or piano, or taken down an octave if the line still works; the clarinet altissimo passage can be simplified or reassigned if it is not reliable. The missing full-band doublings mean she must decide which lines are structural and which are colour. Piano and bass guitar can cover missing inner parts, but the piano should not become a crutch that doubles everything. The 7/8 and 5/4 bars must be kept because Jonah hears them as formal events, but Kiri can write cue marks and simplify the accompanying figures so the ensemble can lock the metre. The tempo should be chosen after trying 132 and 144; the MIDI demo is not a reliable performance tempo. Fidelity means preserving the musical argument, not every written note.
2. How should Kiri sequence the single 100-minute rehearsal?
Read the worked answer
She should spend the first 15 minutes on the metre changes at F and H, because those are the highest-risk ensemble moments and they affect everything around them. She can rehearse those bars slowly, with the drummer marking the pulse and the bass guitar playing roots, then connect them to four bars before and after. The next 30 minutes should go to the main thematic passages and balance, especially where the piano or saxophones are covering missing parts. The middle section can be read through once to identify accidents, but Kiri should resist stopping for every wrong note. The final 30 minutes should be a run of the whole work, followed by targeted fixes only at transitions. The last 10 minutes should be a quiet run of endings and starts, since the programme has two other works. She should also tell the ensemble where she will simplify in performance if needed. The sequencing principle is risk-first, then continuity, then stamina; a single rehearsal cannot fix everything, so it must protect the moments where the piece could collapse.
3. How should Kiri explain the changes to Jonah without damaging his intent?
Read the worked answer
Kiri should frame the changes as instrumentation and reliability decisions, not as judgements that Jonah's music is too hard. She can show him the specific bars and ask which lines he considers essential: 'Is the trumpet high C the peak of the phrase, or can the saxophone take it?' That gives him authority over the musical identity while she controls practical feasibility. She should be honest that the ensemble has one rehearsal and that a failed altissimo or brass extreme would damage the performance more than an octave displacement. She should preserve the metre changes exactly as he wrote them, since that is a clear non-negotiable for him, and offer cuts only in doubling or accompaniment, not in the main thematic material. If a cut is unavoidable, she should propose it as an option and explain the concert context. The goal is a shared hierarchy: what must be heard, what can be reassigned, and what can be simplified. That is more respectful than saying 'the ensemble cannot play it' and more useful than promising fidelity she cannot deliver.
