'Darling is one of Britain’s finest maths writers, [and shows] how inextricably numbers are intertwined with artistic creativity... fascinating.' —Financial Times

'It comes as no surprise that many scientists were also musicians. A Perfect Harmony serves to solidify just how interlinked the fields are... Darling’s observant musical odyssey across time reinforces that “music and maths are endlessly entwined… nourishing one another” and have done so for millennia. After all, at its simplest music is melody and rhythm, and rhythm cannot exist without maths.' —New Statesman

'This deftly written book about the powerful intersections between music, maths and science... he packs in plenty of intriguing facts and anecdotes on a whistlestop tour of musical history... an engaging, accessible guide to a fascinating subject.' —BBC Music Magazine, ????

'Darling is not only a talented science writer with an expansive back-catalogue to his name but he is also an accomplished musician, and his enthusiasm for all things musical spills off the page... if there’s a writer who can genuinely and credibly inhabit both sides of the arts–science cultural divide, it’s Darling... Engaging and entertaining.' —Physics World
