Who knew we should laugh before we go on stage?
Absolutely! Research using visualisation of the larynx during laughing has shown that it helps to release false vocal fold narrowing, so you get a wider space in the throat.
That’s as long as you don’t wheeze when you laugh like Muttley the Dog in the Wacky Races cartoon. If you’re a Muttley-style laugher, use the silent H exercise (No. 3 in our This Is A Voice book) instead.
