Tom Service dips a toe into the choppy waters of Historically Informed Performance Practice. HIPP is the latest term for the well-established vogue of recreating the sounds of music from past centuries. But how can we possibly know what music sounded like before it was recorded? Can HIPP ever be more than a hopeful stab in the dark? Like quinoa and farmers' markets, is it merely another facet of fashion and commercial imperative, a mirror which reflects us and our current concerns straight back at ourselves? Or is it a revitalising and constantly evolving force for good, sweeping away years of lazy and complacent tradition, revealing afresh music we thought we knew? Violinist Rachel Podger and chronicler of HIPP Nicholas Kenyon are on hand to help.
