Harmonia

Overview

Harmonia is a music-theory learning and teaching service built around written notation, composition feedback, and managed coursework. It suits teachers and students working through basic, AP, IB, or college-level instruction, as well as independent learners who want score analysis while they practice. Its strongest case is connecting real-time feedback to a teacher’s course; it is less compelling for someone seeking only stand-alone drills.

Key features

Composition feedback and assessment

Harmonia’s analysis engine reads written music as students compose and flags issues including parallel fifths, poor spacing, and unresolved sevenths. That specificity can help students catch theory problems in context, rather than only answering isolated questions. Tests can be graded automatically, and graded feedback goes to Harmonia’s cloud server for teacher review, linking practice to instructor oversight.

Coursework and teaching materials

The dashboard brings courses, assignments, tests, grades, due dates, timed practice, and class statistics together. Teachers also get a library of hundreds of lessons and exercises and assignment generators for AP-congruent and advanced college material. They can build course materials with score generators or import MusicXML scores. Teacher accounts include all 371 Bach chorales, rather than the 10 available otherwise, giving instructors a substantial source of score material.

Notation playback and the ability to embed audio or video files and links in lessons support teaching with more than written examples. Interactive exercises, advanced notation and harmony tools, MIDI support, and progress tracking round out the learning environment.

Platforms and support

Harmonia supports Android, iOS, macOS, web, and Windows. Its browser version runs in Chrome, Firefox, Edge, and Safari, including Chrome on Chromebooks. Student and teacher pages direct users to support documentation or [email protected]. Users are responsible for keeping passwords confidential and reporting unauthorized access or other security breaches to Illiac Software.

Pricing

Independent practice is free through the Free practice plan, which includes advanced analyzing and feedback features. It is the natural starting point for self-directed learners, but it does not include the course homework assignments and worksheets provided by Classroom Connect.

Classroom Connect is sold once per student, with homework assignments and worksheets for a fixed course period. The options are 20.95 USD per once for up to 4 weeks, 22.95 USD per once for up to 6 weeks, 24.95 USD per once for up to 8 weeks, 28.95 USD per once for up to 12 weeks, 34.95 USD per once for up to 16 weeks, 44.95 USD per once for up to 21 weeks, 74.95 USD per once for up to 42 weeks, and 84.95 USD per once for up to 52 weeks. These are one-time per-student prices, not recurring subscriptions; choose the period that matches the course rather than paying for unused duration.

Testing Only uses custom pricing: single-exam pricing is determined at the testing-period end, while rolling exams are calculated annually and charged every 3 months.

Who it's for

Harmonia is best for music teachers who want to combine score-based instruction, assignments, grading, and class oversight, and for students whose coursework benefits from immediate feedback while composing. Independent learners can use the free practice plan without enrolling in a managed course. Teachers needing course materials can make use of the larger Bach chorale collection and assignment tools; learners looking only for ear training or self-contained theory exercises may find a more focused alternative a better fit.

Pros and cons

Pros

• Feedback on real composition: The analysis engine identifies concrete notation issues as students work, making theory guidance relevant to the score in progress.
• Teacher oversight in the same workflow: Automatic test grading, cloud feedback review, class statistics, and due-date management connect student work with course administration.
• Useful teaching resources: Hundreds of lessons and exercises, assignment generators, MusicXML import, score generators, and all 371 Bach chorales support course preparation.
• Free independent practice: The no-cost plan includes advanced analyzing and feedback, so learners can use the core practice tools without a course fee.

Cons

• Course access costs per student: Classroom Connect requires a separate one-time purchase for each student, which can add up for larger classes.
• Course periods are fixed: The available terms run from up to 4 to 52 weeks, so instructors need to select a duration that fits their course.
• Testing Only pricing is less predictable: Single-exam charges are determined at the testing-period end, and rolling exams are billed every 3 months.

Verdict

Choose Harmonia if you teach or study music theory through written scores and want composition feedback, structured coursework, and assessment in one environment. The free practice plan makes independent analysis accessible, while the paid course terms give teachers a clear per-student route to assignments and worksheets. Look elsewhere if your priority is a narrower self-study tool or you need course pricing that does not depend on each student and course length.
