Phil Hebblethwaite examines five classical musical hoaxes and controversies, from the early twentieth century to the modern day. These are origin stories that have fooled and perplexed some of the greatest experts. In an age of misinformation, when faking it has never been more prevalent, the series unravels the stories of some of the most brazen and confounding composer controversies. What is the appeal of engineering a hoax? And why do we fall for them so easily? It’s a journey that raises questions about scholarship, authenticity and our faith in expert opinion.

In the first essay, Phil tells the story of Fritz Kreisler - the virtuoso violinist who passed his own works off as compositions by forgotten Baroque composers. It took 30 years before the hoax was revealed. How did Kreisler manage to fool so many people for so long?
