This is surprisingly awful, in nearly every dimension. The melodies are approximately random within a given scale, the harmonies are aimless, and the instruments are the cheesiest I've heard in over a decade. There have been <i>numerous</i> algorithmic and automatic and learning composers over the years that are better than this, at least from an aesthetic perspective, or at least on par.<p>It's a hard problem, but I honestly expected something much more interesting from Wolfram. At the very least someone making something like this ought to make an effort to understand the current state of the art in the field.
