Before MySong from Microsoft Research, people without musical talent had to resort to consuming music and not bothering the rest of us with their amateur stylings. No longer. All you have to be able to do is sing a short tune (provided you can sing somewhat on key) and this MySong software will dynamically generate a piano accompaniment just for you.
As you can see in the video, it actually sounds pretty good, and you can adjust the sliders to make the piano part happier, sadder, jazzier, or not quite so jazzy. The bad news is that this is just a Microsoft Research project, not an actual package you can buy. Maybe in a few years? [IStartedSomething via Geekologie via Dvice]
