As TechCrunch notes, the company is most likely diversifying to ensure its survival and income growth in the future. It also has an English Test app for language certification and a Math app that uses colorful animations and interactive exercises to help people learn multiplication, division, fractions, geometry and measurements.

If and when Duolingo's Music app comes out, it will join the company's growing list of learning applications that include its ABC app, which teaches kids how to read and write. They also have to take the lead on curriculum development, which signifies that the app is still in its very early stages. The job ad is for an 'expert in music education who combines both theoretical knowledge of relevant learning science research and hands-on teaching experience.' Whoever gets the job will be in charge of making sure that the app is 'well-grounded in learning science.' They have to translate 'research findings into concrete ideas' that can be used for 'learning by doing' activities that Duolingo is known for.

According to a job posting (seen by TechCrunch), Duolingo has a small team that's currently working to build an app for teaching music. It has ventured into other subject matters over the years, though, and now it looks like the company is also hoping to be the one people turn to when they want to learn about music. You most likely know Duolingo as an app you can fire up when you want to learn a new language or at least familiarize yourself with the local tongue of a place you're visiting.
