Sometimes I think I’m a jack of many trades and master of none. But on a good day I tell myself that, as a historian, there may be some merit in this. History – of all disciplines – surely invites cross-fertilisation with others. Yet I sense that much historical research continues to be specialist and, in general, to marginalise the arts (especially ‘classical’ music), historians preferring to leave them to the experts. For its part, much arts history continues to be largely preoccupied with its own often esoteric subject matter.
