“Research has shown that some people, termed ‘amusic’, can neither produce nor perceive music. It isn’t a problem of the ears – they can understand other sounds perfectly well – but when it comes to music, all tunes sound the same. It’s no surprise, then, that music, which tends to move in small steps, is literally ‘lost’ on them. Though most amusia sufferers find listening to music pointless, some even find it annoying and unpleasant.”
