How a choir learns to tune itself
Tuning in an a cappella choir is not fixed by a keyboard. The singers adjust to each other, constantly, by ear.
Ask a group of singers what they are doing during a sustained chord and the answers are remarkably technical. They are not holding a note — they are making continuous small adjustments against what they hear around them, and a chord that sounds effortless is usually the product of four people quietly negotiating.
On blend
"You aim to disappear into the chord, not sit on top of it."
On breath
"We stagger our breathing so the line never stops."
On tuning
"A pure third is slightly lower than a piano's. You feel it lock."
On text
"If the words are clear, the music mostly takes care of itself."
Why a piano is the wrong reference
Keyboard tuning compromises every interval slightly so that all keys work equally well. Voices have no such constraint, and a chord tuned purely rings in a way an equal-tempered one does not. Singers describe the moment it happens as the chord "locking" — the beating between the notes simply stops.
What rehearsal actually consists of
- Long slow chords, listening rather than singing loudly.
- Speaking the text in rhythm before anyone sings it.
- Rehearsing in the performance space whenever it can be arranged.
- Swapping positions so everyone hears the chord from another side.
