Royal music throughout the ages. Tom Service asks: what makes it sound royal, and why? And is there really such a thing as a royal sound world?

Royal music doesn’t have to be heraldic, ranging from the pomp and ceremony of Elgar; to the intimacy of lutenists like Dowland writing in the court of Christian IV in Denmark; to the secret music of the Kyoto imperial court, performed exclusively for royal ears. Composers over the centuries and millennia have written for kings, queens, princes and princesses, at times simultaneously praising and even criticising monarchies from within and without.
