Think you are tone-deaf or lacking in musical talent?
Explaining its doodle, Google wrote, "Made in partnership with the Google Magenta and Google PAIR teams, the Doodle is an interactive experience encouraging players to compose a two measure melody of their choice".
Bach was born on March 21, 1685, in a small town of Eisenach in central Germany. The doodle then uses machine learning to harmonize the custom melody into Bach's signature music style with the press of a button. Or, if you're lucky enough to find the easter egg in the Doodle, you may end up with an '80s rock style hybrid.
Machine learning happens when engineers teach a computer to come up with its own answers by showing it examples from a data set.
To develop the doodle, the teams created a machine-learning model that was trained on 306 of Bach's chorale harmonisation. Today's doodle is one such, and it's even more special if you are a Bach fan! They then fed that model 306 Bach chorale harmonizations, which are ideal for training since they always feature four voices that have their own melodic line.
The German musician knew how to fix the complex inner mechanisms of pipe organs, which is shown in today's Google doodle. Google PAIR (People + AI Research) then used Google's TensorFlow.js to allow the AI to run on web browsers directly rather than offloading it to a remote server. His father not only knew how to play multiple instruments but also worked as a director of the musicians in town.
Google has also developed a way for musicians to play with Coconet: an interface called Coucou. Publishing of a number of works followed and, by 1900, all of his known works were published and this era is famously known as the "Bach revival". However, more than 1,000 that survived in manuscript form are now published and performed all over the world.
