Sir Roger Norrington, the trail-blazing pioneer of the early music movement, died last week aged 91.
 

He had one of the biggest impacts on classical music of any conductor of his generation.
 

When he first began evangelising for "authentic" performances of baroque music in the 1960s — rearranging orchestras on stage, thinning the strings down to the numbers composers wrote for and all playing on gut strings without vibrato — many of his musical colleagues and critics were outraged.
 

But Norrington persevered with forensic scholarship and an evangelistic fervour, taking his almost pathological aversion to vibrato into the realm of modern-instrument orchestras.
 

Norrington leaves a legacy as a pioneer for a movement that combines music and historical research. Mairi Nicolson pays tribute to his career.
