Harmonia

Overview

Harmonia is a music-theory learning and teaching service built around written-score analysis and course assessment. It suits teachers who want student composing work, assignments, and grading in one online workspace; independent learners can use its free practice plan. Its strongest case is guided study with immediate notation feedback, rather than a general-purpose music-learning app.

Key features

Score analysis and assessment

Harmonia’s analysis engine reads written music in real time and flags issues such as parallel fifths, poor spacing, and unresolved sevenths. Students get feedback while composing, and tests can be graded automatically. That combination can help instructors give students timely, specific direction while reducing routine grading; it is most relevant to notation-based theory work, not practice that does not involve written scores.

Graded feedback is sent to Harmonia’s cloud server for teacher review. Teachers can play back notation and embed audio or video files and links in lessons, connecting score work with listening materials.

Course tools and teaching content

The dashboard brings together courses, assignments, tests, grades, due dates, timed practices, and class statistics. Teachers also get a library of hundreds of lessons and exercises, assignment generators for AP-congruent and advanced college material, and score generators. MusicXML imports let teachers bring scores into course materials. Teacher accounts include all 371 Bach chorales, rather than the 10 available otherwise.

Interactive exercises, advanced notation and harmony tools, MIDI support, and progress tracking round out the learning environment. The feature set is substantial for theory instruction, though its course dashboard and teacher resources matter less to someone looking only for occasional self-study.

Pricing

Free practice costs 0.00 USD per free and provides independent practice with advanced analysis and feedback features. It is the natural starting point for learners studying on their own, but it does not include the stated course homework assignments and worksheets of Classroom Connect.

Classroom Connect is billed once per student, with course homework assignments and worksheets for the selected course duration:

• Up to 4 weeks: 20.95 USD per once
• Up to 6 weeks: 22.95 USD per once
• Up to 8 weeks: 24.95 USD per once
• Up to 12 weeks: 28.95 USD per once
• Up to 16 weeks: 34.95 USD per once
• Up to 21 weeks: 44.95 USD per once
• Up to 42 weeks: 74.95 USD per once
• Up to 52 weeks: 84.95 USD per once

Choosing a longer course means a higher one-time charge per student, so instructors should match the duration to the course rather than assume a recurring subscription. Testing Only uses single-exam pricing determined at the end of the testing period; rolling exams are calculated annually and charged every 3 months. That option may fit exam-focused use, but its custom pricing makes the cost harder to plan in advance. A free trial is offered.

Platforms

Harmonia supports web, Windows, macOS, iOS, and Android. Its browser version works in Chrome, Firefox, Edge, and Safari, including Chrome on Chromebooks, giving students options across common desktop and mobile platforms.

Who it's for

Harmonia is best suited to music teachers working with basic, AP, IB, or college-level theory, especially when they want score analysis, assignment management, and assessment together. Students benefit most when a teacher uses its courses and feedback workflow. Independent learners can use Free practice, but those seeking only a focused ear-training or rhythm app may find the teaching-oriented feature set unnecessary.

Pros and cons

• Pros: Real-time feedback identifies concrete notation and harmony problems, helping students correct work as they compose.
• Pros: Automatic grading, class statistics, and course management bring assessment and administration into the same dashboard.
• Pros: Hundreds of lessons and exercises, score generators, MusicXML import, and the full Bach chorale collection give teachers substantial material to build courses.
• Cons: Classroom Connect charges per student, and the cost rises with course length; this is a material consideration for longer classes.
• Cons: Free practice is for independent use, while course homework and worksheets are tied to paid Classroom Connect.
• Cons: Testing Only pricing is determined after the testing period, which makes advance budgeting less straightforward.

Verdict

Harmonia is a strong fit for teachers who want written-score analysis, student feedback, course materials, and grading in one service. Its free independent practice gives learners a way to use the analysis tools without committing to a course, while Classroom Connect prices scale with both student count and course duration. Look elsewhere if you need a narrower self-study tool or want a predictable free course rather than teacher-led coursework.
