Automatic music composition is not a new area of research, the first technique was to create several rules for the computer to follow. This technique can give some appreciable results, but music is more complex than a series of strict rules. A lot of people think that composing music can only be achieved by humans and that a machine is not intelligent enough to create pleasing music. This may be true for now, but it may be that there is still some information about musical structure and repetition that can be learned from all the existing examples by fairly simple models and that can be used to compose more melodic songs.
