AI-powered Google Doodle celebrating Johann Christian Bach lets you create custom melodies

In a first, Google celebrated renowned German musician Johann Christian Bach with an AI-powered doodle.

Made in partnership with the Google Magenta and Google PAIR teams, the doodle, powered by artificial intelligence (AI), is an interactive experience encouraging netizens to compose a two-measure melody of their choice.

With the press of a button that is located at the bottom right corner, the doodle uses machine learning to harmonise the custom melody into Bach's signature music style.

Bach was born and raised in the German town of Eisenach in a large musical family. His father played multiple instruments and worked as director of the town's musicians, while his eldest brother was also a musician.

Primarily known as an exceptional organist during his lifetime, Bach also understood how to build and repair the complex inner mechanisms of pipe organs, a feature that has been incorporated into the interactive doodle.

Bach's reputation soared following the 19th century "Bach revival," as the music world gained a new appreciation for his innovative use of four-part harmony, modulations of key, and mastery of counterpoint and fugue.
