I enjoyed your article 'I don’t stutter at all if I’m singing' about Chris Charlesworth.

Mr Charlesworth touches upon a phenomenon that has existed since there have been records of man: people who stammer can sing fluently.

Some experts suggest that since speech is a left-brain function, and stuttering is a right-brain function, there is no correlation at all between singing and speaking because they are functions from different sides of the brain.

While this argument sounds plausible, there is absolutely no empirical evidence to explain why people who stammer sing fluently.

Mr Charlesworth is in good company because many famous singers have found fluency through singing, such as Carly Simon, Paul Young and Gareth Gates.

The Stuttering Foundation (www.stammeringhelp.org) has a list of famous people who stammer, including many singers. This website also provides many free resources for people who stammer.

In addition, their list includes many famous British people such as Emily Blunt, Lewis Carroll, W Somerset Maugham, Jane Seymour, Gareth Gates, Kim Philby, Indiana Gregg, Philip Larkin, Andrew Lloyd Webber, Charles Darwin, Winston Churchill, and some others.
