The keyboard can be played using your computer keyboard (hint: tap the numerical keys to reach the black notes) or triggered using your mouse. Click and drag the knobs to change the keyboard sounds and hit record (on up to four tracks) when you are ready to save your composition.

“Celebrate synthesiser pioneer Robert Moog’s 78th birthday by tweaking [k]nobs and playing some melodies on today’s Doodle!” posted Google Australia on its Google+ page announcing the Doodle.

American visionary Robert Moog is hailed as one of the founders of electronic music and is credited with inventing the Moog synthesiser.

“With his passion for high-tech toolmaking in the service of creativity, Bob Moog is something of a patron saint of the nerdy arts and a hero to many of us here,” said Joey Hurst, Software Engineer at Google. “So for the next 24 hours on our homepage, you’ll find an interactive, playable logo inspired by the instruments with which Moog brought musical performance into the electronic age.”
