A choral singer inhaled some helium and hit the high C in Allegri’s Miserere

How do you get over the problem of your boy sopranos' voices breaking? A massive helium balloon. Here's how it sounds in Allegri's Miserere.

Choirboys have a pretty tough life. For years, they’re praised and admired for their beautifully angelic high Cs – but then puberty kicks in, and it all goes to pot.

The Choir of King’s College, Cambridge has found a solution for this inconvenience. Instead of finding a soprano to hit the top notes, they have discovered that a balloon of helium does the job just as well.

In this performance of Allegri’s ‘Miserere’, a male university student is able to hit a C6 – a soprano C, to you and me – simply by inhaling a gulp of helium from a giant balloon.

Allegri’s ‘Miserere’ was famously transcribed and brought into the public domain by Mozart in 1770. The young composer, then aged just 14, supposedly heard the piece once at a concert, went back home and wrote down the whole thing note for note.

In all seriousness, this video was filmed as an April Fool’s prank in 2014, and has since racked up well over three million views on YouTube.

Well played, guys.
