Artificial intelligence is finding its way into the world of music, literature and art, raising never-before-considered questions about a creator's role.
A team led by Shigeki Sagayama, professor of mathematical engineering and information physics at Tokyo's Meiji University, has created software that can compose a melody to accompany any given lyric.
Available for use online, the automatic composition software, named Orpheus, has produced hundreds of thousands of pieces of music since its launch in 2007.
