Sony develops algorithm based AI music

A future chart-topping song may soon come from an algorithm. Sony Computer Science Laboratory (CSL) in Paris is developing a system of algorithms which can create songs that cater to the user's taste, based on styles adapted from existing music. The starting point of the song creation is a database of sheet music of more than 13,000 existing songs, from which the user can choose any number of titles with a sound or feel they would like the new song to incorporate. The algorithm analyses the songs' characteristics, and statistical properties related to rhythm, pitch and harmony. It will learn, for instance, which notes "go well" with a given chord, what chord is probable after a given chord, or which notes usually follow after a given note.
