musictheory.net review: excellent free drills with surprisingly good teacher tools
Animated theory lessons, note and interval drills, ear training and permanent links to customised exercises are free and ad-free on the web. Progress reports help teachers check a task, but this is no replacement for playing music.

Pros and cons
What we liked
- All web lessons and drills free and ad-free without an account
- Exercises cover written notation, keyboard, fretboard and ear training
- Teacher customiser produces permanent exercise links and challenge limits
- Progress reports and verification codes work without a server-stored student profile
What we didn’t
- The visual design is deliberately spare rather than game-like
- Recognition exercises do not measure fluent performance on a real instrument
- Offline practice and some enhanced features live in optional paid iOS apps
musictheory.net offers animated explanations and a remarkably wide set of free exercises: staff and keyboard note identification, intervals, scales, chords, fretboard work and ear training. The web version is ad-free and does not ask for a student account.
Practice one thing at a time
The lessons begin with the staff and note lengths, then move through keys, intervals and harmony. The exercise catalogue is more useful than a single all-purpose quiz because the teacher can choose exactly what to recognise: a note on a stave, a keyboard key, a chord by ear or an interval on a fretboard.
The site is intentionally plain. There are no characters or streak animations to disguise repetition. For a student who wants a precise drill that is a strength; for someone who needs rewards to persist it may be a limitation.
The teacher feature is easy to overlook
The Exercise Customizer creates a permanent URL with settings and an optional question or time limit. The FAQ explains a signed Progress Report with a verification code that reconstructs the result locally; the site says codes are not stored on its servers. It recommends initials or another identifier instead of full student names.
- Set a narrow note range for a learner who is still finding a clef.
- Use Challenge Mode for a bounded homework task rather than an endless exercise.
- Ask for a played example after a successful identification drill to connect screen answers with music.
