Many people, of course, poo-poo the air guitar. They say it’s nothing but a load of overgrown schoolboys jumping around a stage, thrusting their groins at the audience and wiggling their fingers in an orgy of faux-frottage that puts even Miley Cyrus’s twerkish masturbations in the shade. But they are wrong.

For researchers from Cambridge, Oxford, King’s College London and Royal Holloway have studied student musicians at the Guildhall School of Music and the Royal College of Music and concluded that leaping and gyrating around the place, playing the air guitar could be a genuinely inspirational activity. It’s the fact that they’re not actually working at their real instruments that frees musicians’ imaginations. And, the boffins added, singing in the shower gets their creative juices flowing, too.
