Improve the Quality and Speed of Learning

Feedback is one of the most important ways we learn new skills

Students don't need to wait for days to find out their grade - they can find out in seconds with Harmonia. You can allow students to submit assignments multiple times, redo part writing automatically transposed to different keys, or incremental grading that allows them to grade only what they've completed as they progress through an assignment.

Create Your Own Worksheets

Or use anything from our library

Whether your own, or ours, or a practice, homework, or exam, all Harmonia documents are completely interactive, intelligently analyzed, and automatically graded.

Configure Your Course

Detailed settings accommodate your class syllabus

Have a proficiency based course? Want to allow late submissions? From due dates, allowing multiple submissions, uploading the student's file automatically, and grading rubrics, you can configure your course any way you like.

Automatic Grading

Let Harmonia collect homework and grade for you

Grading takes milliseconds, not days, and student worksheets can be automatically uploaded and stored for you. Now you can focus on what you do best — delve into the music literature, apply theory in meaningful ways, and teach music, and not just part writing rules.

Statistics and Gradebook

See how students are doing at a glance

Simple statistics tools let you see the grade distribution, the mean, standard deviation, and more. View the entire spreadsheet online, or download your gradebook as a CSV (comma separated values) file that you can import into your favorite software.
