Kat, I agree wholeheartedly that my example was not music and when I first played it back, my first thoughts were of some modern classical pieces that I have heard. I hadn't realised that some of it had literally been churned out a computer but in a way, I am pleased to know that some of the crap (IMO) that I have heard might not have been produced by a human being.

Assuming that we all can agree that some sequences of notes simply are not music: What makes one sequence acceptable to our ears and another complete and utter nonsense?

How much of this is down to what we are used to hearing? Chineese music for example sounds completely alien to me but it must be enjoyed by the people living there.
