Johann Sebastian Bach, Baroque German musician and composer, honored this Thursday (21) with a figure on Google's homepage. The seeker decided to celebrate the artist's birthday in a special way: by developing the first Doodle with artificial intelligence.
The search giant's traditional logo has been replaced by an interactive animation that encourages users to compose their own melody. The illustration features Bach playing a pipe organ, an imposing musical instrument introduced in western churches from the X century, while the letters that form the word Google rotate above.

By pressing the Doodle play button, the user can write in the score by inserting the notes and changing the speed with the beats per minute, for example. Then, just click harmonize so that the machine learning technique, data analysis method in which systems can identify patterns and make decisions with the minimum of human intervention, to adjust the custom melody in the musical style of music.

If the user finds a special easter egg, they can listen to an 80's hybrid rock-style Bach. You can share the unique music creation with friends or save it in .MIDI format.

Developed in partnership with the Google Magenta and Google PAIR teams, Doodle is primarily possible thanks to two technologies. The first is the Coconet machine learning model, developed by expert Anna Huang and capable of performing a wide variety of musical tasks.
Coconet was trained in 306 of Bach's coral harmonizations. Their choirs always have four voices, each carrying its own melodic line, while creating rich harmonic progress when played together, the search giant noted. Already the open source library TensorFlow.js, the second technology employed in the project, allows machine learning to take place entirely within the browser, eliminating heavier servers.
Who was Johann Sebastian Bach?
Born in the small German town of Eisenach on March 21, 1685, Johann Sebastian Bach is considered one of the greatest geniuses of western music. In addition to playing, the organist also understood how to build and repair the complex internal mechanisms of tube organs, represented in interactive Doodle.
Aged 65, the musician died on July 28, 1750 and lived to see only part of his work published. Bach left behind more than a thousand manuscript works, which are now published and performed around the world.
