Google released on Thursday its first ever artificial intelligence-powered doodle to honor the German composer Johann Sebastian Bach's birthday, The Verge reported. 

“With the help of artificial intelligence, the interactive Doodle allows users to generate harmonies for any melody they input in the style of the famous 18th century composer. Google used machine learning to analyze the harmonies of more than 300 Bach compositions, replicating the patterns it found to fit the user’s suggested melody,” the source noted.

The developers used the composer’s chorales with missing notes and asked artificial intelligence to restore them.
