Primeira música pop composta por inteligência artifical

O Sony CSL Research Laboratory publicou duas músicas totalmente compostas por inteligência artificial através do software Flow Machines.

O software consegue compor músicas dentro do género que lhe é “ensinado”. Para isso, é-lhe fornecida uma grande quantidade de músicas com estilo semelhante. Depois de composta a música, o compositor Benoît Carré trata dos arranjos e produção.

A primeira música, Daddy’s Car, foi escrita ao estilo dos Beatles:

 

A segunda música, The Ballad of Mr Shadow, teve por base o estilo musical de compositores como Irving Berlin, Duke Ellington, George Gershwin and Cole Porter:

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 called FlowComposer. 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.
