Does someone's personality come out in their writing?

This is something I've been wondering for a while. If you look at the question of what a personality actually is, it seems a remarkably complex thing. Surely it would be difficult to identify someone's personality uniquely through something as limited as the words of a few sentences? or perhaps a few musical phrases? or a few brush strokes?

However, I think that you can spot the hallmarks of someone's personality in their writing. People who read the drivel I write tend to notice my turn of phrase and, when I'm writing informally, the timing and cadences of how I speak. I overuse ellipsis and hyphens in my informal writing in order to create the impression of my timing (or maybe they're a sign of the disorder in my mind).

Likewise, I'm convinced I can spot the hand of certain favourite composers in their writing. In my case, I'm talking about the composers of musicals, since I've gone musicals mad. I suppose, I'm spotting tunes that seem to share similar small phrases with other tunes from the same composer. Andrew Lloyd Webber is a good example. Indeed, I can recognise individual orchestra chords from the man as being typical of his touch.

So, if you read this blog and form a judgement of the man behind the words, you're probably judging some aspects of the real me. Be gentle with me.
