The Ensemble That Cannot Hear Itself
A five-piece VET ensemble (two guitars, bass, drums, keyboard) is preparing a 15-minute set for assessment. In the rehearsal room they sound balanced, but a recording made on a phone reveals the bass is inaudible and the drums dominate. The room is small and carpeted; the assessment venue is a large hall with hard floors and high ceilings. The guitarist turns up his amp whenever he cannot hear himself, and the keyboardist has started playing louder to compete. The drummer says he is playing at the same volume as always. Assessment is in four weeks, and the group has never rehearsed anywhere but the small room.
1. Explain why the ensemble sounds different in the recording and will sound different again in the hall, and why the guitarist's response makes things worse.

Room acoustics and instrument projection. In a small carpeted room, high frequencies are absorbed by soft surfaces, and instruments are close together, so players hear each other through a mix of direct sound and their own instrument's proximity. A phone recording captures a different perspective, typically from one point, and reveals the actual balance: bass frequencies that the players felt through the floor and body are underrepresented on the recording, while drums, being the loudest acoustic source, dominate.
The hall will change everything again. Hard floors and high ceilings produce strong reflections and longer reverberation. Low frequencies build up and can become boomy, while reflections can make it harder to hear individual parts. The balance they have achieved in a dead room will not transfer.
The volume spiral. Turning up an amp to hear oneself raises the overall level, which prompts others to raise theirs. This is a loudness war that increases stage volume without improving clarity, and it risks hearing damage. The correct response is to reduce the loudest source (drums) and use arrangement and EQ rather than raw volume.
2. Propose concrete steps the ensemble should take in the four weeks to ensure a balanced, audible performance in the hall.

Rehearse in the assessment venue. Book at least two rehearsals in the hall, or a similar large hard-surfaced space, so the group hears the real acoustic. Adjust positions and amp settings there, not in the carpeted room.
Control the drum volume first. The drummer should play with appropriate dynamics for the room and, if needed, use lighter sticks or brushes for quieter numbers. Since drums are acoustic and set the floor for everyone else, reducing them lets the others come down.
Set levels by listening, not by feel. Have one person stand out front during a run-through and report the balance. Use the recording as a reference but trust the live front-of-house perspective for the hall.
Use arrangement to create space. Vary which instruments play in which sections so parts do not compete for the same frequency range. The bass should be audible through note choice and amp EQ (boost low-mids, cut mud) rather than sheer volume.
Protect hearing. Agree on a sensible stage volume and consider earplugs, especially with drums in a reflective hall.
