Just why are choristers’ voices so beautiful? Science has the answer
The magical sound of choristers’ voices has filled the UK’s chapels and cathedrals for centuries. But what gives their singing voices that spine-tingling quality?
Why are choristers’ voices so distinctive?
In an attempt to quantify what makes their voices ‘shimmer’, Professor David Howard of the University of York carried out a study on children’s voices.
By placing young volunteer singers in an anechoic chamber – a room designed to prevent reflection of sound – and measuring the acoustic frequencies of their singing, he hoped to identify exactly what gives their voices an ‘angelic’ quality. Although it seems clear that how choristers are trained – and there are as many different approaches as there are choir trainers – will affect the sound, Howard found certain acoustic frequencies recurring.
‘You get this really shimmery sound’
‘In our experiments it looks as if that particular ‘ring’ is happening above the normal speech area, in the region up around 8,000Hz, where there is something appearing when you get this really shimmery sound to choristers’ voices,’ says Howard to BBC News.
The use of such research could lead to developments in choir training methods to hone the voice to produce these frequencies. Professor Howard even suggests that it could allow a computer to synthesise a beautiful choral sound.
‘Maybe you can get to the point where maybe the computer could be at the back of the choir,’ he says. ‘It’s a speculative thought, and I think we might get the acoustic right. But what we don’t know is the emotional driver – and I think that is a long long way off.’
Training, technique, acoustics and more
Of course, there are other, far more predictable factors that make choristers’ voices sound so beautiful. The key factors that help produce that harmonious and ethereal sound include:
Training and Technique
Choristers, especially those in professional or cathedral choirs, undergo rigorous vocal training. They are taught techniques like breath control, proper vowel shaping, and tone production, which ensure clarity and uniformity in their singing. These techniques enable them to sustain notes with precision and blend seamlessly with others.
Age and Vocal Quality
Children’s choirs often feature treble voices, which naturally possess a light, pure, and angelic timbre. These qualities, combined with disciplined training, produce a uniquely enchanting sound.
Choral Blending
Choristers are trained to listen attentively to each other, matching pitch, dynamics, and tone. This results in a unified sound where no single voice dominates, creating a cohesive and balanced performance.
Acoustics
Many choirs perform in spaces with excellent acoustics, like churches or concert halls. The architecture amplifies and enriches their sound, enhancing the overall listening experience.
Musical Repertoire
Choristers often sing pieces composed specifically for choral groups, designed to highlight their vocal strengths. Works by composers like Palestrina, Handel, or Britten are crafted to make the most of their resonant, layered sound.
Emotional Connection
The beauty of a chorister’s voice is not only technical but emotional. Their singing conveys deep emotion and spirituality, often moving listeners on a profound level.
Discipline and Teamwork
Choirs emphasize discipline and collective effort. This mutual dedication ensures precise performances that elevate their voices from mere sound to a transcendent experience.
