SONY CSL Research Laboratory created two entire songs composed with Artificial Intelligence, using Flow Machines.
How it works:
1) We set up a database called LSDB. It contains about 13000 leadsheet from a lot of different styles and composers (mainly jazz and pop about also a lot of Brazilian, Broadway and other music styles).
2) The human composer (in this case Benoît Carré, but we are experimenting with other musicians as well) selected a style and generated a leadsheet (melody + harmony) with a system calledFlowComposer. For Daddy’s Car, Carré selected as style “the Beatles” and for Mr. Shadow he selected a style that we call “American songwriters” (which contains songs by composers like Cole Porter, Gershwin, Duke Ellington, etc).
3) With yet another system called Rechord the human musician matched some audio chunks from audio recordings of other songs to the generated leadsheets.
4) Then the human musician finished the production and mixing.
