It must be an almost insuperable challenge to write a ghost story these days. A really good ghost story must somehow trick the reader, leading step by step from quotidian rationality into the deep caves of the psyche, finally inducing a scurrying back in desperation, a clinging to the comforts of reason and habit. M. R. James and Arthur Machen were masters of the genre, and let us not forget Algernon Blackwood, who is inclined to be underestimated these days. Modern tales of the supernatural seem to depend more or less on explicitly horrible events, violent scenes and unpleasant descriptions after the manner of much of Stephen King; good for making graphic, blockbuster movies for the masses but in my view they are not truly frightening at all.
Can the spirit of the ghost story exist in music ? Curiously, I was discussing this with our late friend, David April, in emails a few years ago. He asserted that the music of Frank Bridge, in particular, seemed to him replete with evil. I replied that, while not going that far, I agreed that much of his piano music reminded me of a seaside town out of season with mad Uncle Charlie locked in the attic. It is recorded that both Machen and James actually believed in the external existence of the supernatural, which they considered invariably evil and took pains to discount benign ghosts altogether.
So what can the modern, scientific but also artistic mind take from all this ? Probably a good deal when we consider the undoubted presence of Jung's shadow deep in every psyche. We ignore these manifestations lurking in the deep recesses of our minds at our peril but, brought to the conscious surface of an otherwise healthy mind, they lose their power to do serious harm and may indeed lead to greater self-understanding.
So after this circumlocution, Andrew, I say carry on playing these eldritch and numinous creations for us.
