In the top-right corner of the EarSketch page, click on Start Coding.
Press the black Start button.
After the tour, create an account for yourself.
Find the curriculum in the right pane of the EarSketch window… it should say “Welcome” at the top. Click on Welcome, read the text, then click on the right arrow in the top-right of the window. Continue to follow the instructions through Unit 1, Chapter 4. By then, you should have created a pretty cool audio loop!
