Brian, the 'device' is an intellectual process not a software one although I suppose it might be possible to write a piece of software to do it. It's something I came upon in a book when doing another project and the writer outlined his way of analysing melodies in such a way as to reduce the intervals to a numeric pattern. He was then able to compare these patterns. I'll try to locate the book and the method as soon as possible - time permitting.

I'm intrigued. Any progress on finding the book?
