Andrew Green mines the BBC archive for great moments from masterclasses of the past and tracks down students who are now well known in their own right. In the last of three programmes, string players remember their conversations about vibrato techniques and the operatic nature of Mozart's instrumental music.
Great moments from the archive include 1960s masterclasses with Paul Torteiier and Henryk Szeryng and 1970s masterciasses with Yehudi Menuhin , from which violinists
John Holloway and Marcia Crayford recall his inspirational teaching.
