# Bach Google Doodle

Bach Google Doodle was Google's first AI-powered interactive doodle, launched March 21st, 2019 for J.S. Bach's 334th birthday. Players drew a short melody and a machine learning model harmonized it in the style of a Bach chorale, sparking a wave of playful compositions shared on Twitter.

## Overview
Bach Google Doodle was Google's first AI-powered interactive doodle, built with Google Magenta and Google PAIR to mark the 334th birthday of composer Johann Sebastian Bach[1]. On the doodle, users drew two measures of melody onto a staff, hit harmonize, and a machine learning model filled in alto, tenor and bass lines around the tune to produce a four-part chorale in Bach's style[1].

The model was trained on 306 Bach chorales so its output leaned on the same voice-leading patterns as the real composer's church music[1]. The finished piece could be played back or downloaded in four-part counterpoint, which is what turned the doodle from a one-off tribute into a Twitter game people shared for days[1].

## How It Spread
Once the doodle was live, users flooded Twitter under the hashtag #BachDoodle with their AI-harmonized compositions. Classic FM rounded up standout entries on March 22nd, 2019, highlighting a Bach-style rework of Undertale video game music, a Bach chorale built on a Webern tone row, and a Baroque arrangement of Queen's Bohemian Rhapsody[1].

The same weekend, the @GoogleDoodles account teased an Easter egg hidden inside the doodle: clicking a small guitar amp in the background switched the engine into a rock setting that layered electric guitar and drums over the AI-generated counterpoint[3]. That extra mode gave Twitter a second round of clips to trade, with users posting metal takes on their earlier chorale attempts[3].

Even after the two-day run ended, the Bach Doodle was cited in follow-up coverage as an early consumer-friendly demo of Google Magenta's music AI work, and stayed a common reference point when Google shipped later interactive doodles[1].

## How to Use
To play, users draw a short soprano melody across the two-measure staff and press the harmonize button, and the model fills in the three lower voices in a Bach chorale style[1]. Common tricks include sticking to notes that outline a clear key so the harmony sounds cleaner, downloading the MIDI to share the composition on Twitter, or clicking the guitar amp hidden in the background to switch the same harmony into a rock arrangement[3].
