Welcome to the jubal product page!
Jubal is an app written for iOS devices that will help budding improvisors to learn the art of “hearing” and “playing”. Jubal creates exercises for you on the fly, and you play what jubal dictates. As you do, you get better and better at playing by ear. This is a foundational step toward playing what you hear in your own head.
