We are all familiar with the mannered walk, the impeccable attire, the courteous doff of the hat. But what is it, in particular, that embodies this interpretation of Poirot?
In an absorbing interview, given at the launch of a new series, David Suchet contended that personality is embodied not in appearance, but in the sound we make . . . hence 'personality', which stems from its Latin root, 'per sona'. We are 'our sound', and it is this unique, instantly recognisable sound which carries within it our inner essence. By this understanding, it is not the physical image, but the clipped tones, distinctive accent and modulated delivery that constitute the essence of an unforgetable Hercule Poirot.

Nor is it just the sound of the voice. I'm sure you've noticed how film-makers use their knowledge of sound to skilfully manipulate our feelings.
A person walks into shot and immediately you know you are encountering one of the 'bad guys'. How do you know this? It's the music that tells you. To make certain that you are not led astray by any fanciful notions of your own, the music anticipates every turn of the plot with appropriate under-scoring, and never fails to pull out the sweeping strings for an orchestrated happy ending. Words are superfluous . . . the background music is a wholly reliable narrator.

Music, it would seem, is the universal language. Voiced by every aspect of creation, it is found everywhere. I hadn't realised, had you, that there is no region of the world where music is not an inseparable aspect of human existence?

Could it be recognition of the communication and unity achieved by sound that has given rise to the recent popularity of choral singing?

Whether it be the tone of the voice or the music of the spheres, sound both unites and informs. It is common to all of us . . . and, as we now know, it is one of many mysteries effectively solved by the little grey cells of Hercule Poirot!
