In 1924, Beatrice Harrison broadcast a miracle to the world: a wild nightingale singing with her cello. Over a million people tuned in to hear the nightingale that night, and the BBC went on to broadcast their duet worldwide every spring until 1942. This transformed the public interest in nightingales – a species already in decline. If Beatrice’s duets with the nightingales touched a chord with the world, her own life proved to be as musical, free-spirited and inspiring. From her early years as a musical prodigy to recording with the most important composers of the day or playing for the wounded in the Second World War, Beatrice’s warmth and love for sharing music are as endearing now as they were to her original audiences.
