FROM THE STUDIO
“Most apps teach you to press the right thing at the right time. Atlas teaches you the instrument.”

Questions about Atlas
- What is Atlas?
- Atlas is a free set of interactive labs that show the maths and physics inside every instrument. You move a real mechanism, such as a string, a slide or a drum rhythm, then watch it and hear it respond.
- Who is Atlas for?
- Atlas is built for school classrooms and curious students, from primary school to older students who enjoy the theorem machines. It covers piano, guitar, drums, voice, trumpet, trombone, bass and banjo.
- Is Atlas free?
- Yes. Atlas is free for everyone, with no account, no score and no gate.
- Does Atlas work on a phone or a Mac?
- Atlas runs in a web browser, so there is nothing to install. Turn the sound on to hear each demonstration.
- Who made Atlas?
- Atlas was made by Jason Zac at Nathaniel School of Music in Bangalore, India.
