Music theory practice you can hear and try.
Music theory makes more sense when you can use it. Read a note, build a scale, hear a chord and check what you chose. Start with one skill below; you do not need an account.
New to reading music?
Start with Note Name Checker. Learn the spaces and lines inside the treble staff before adding ledger lines or changing clef. You can name a written note or place a given note on the staff. If you are finding your way around a keyboard, try piano note-name practice alongside it.
Build scales instead of memorizing pictures
Use Scale Builder to hear notes as you select them. A major scale follows whole step–whole step–half step–whole step–whole step–whole step–half step. On C, that gives C–D–E–F–G–A–B–C. Start the same pattern on G and F becomes F♯. The pattern matters more than whether the keys are white or black. Follow up with key-signature practice to connect those sharps and flats with major and minor keys.
Understand how chords fit together
In Build a Chord, begin with major and minor triads. C major is C–E–G; C minor lowers E to E♭. Both use a root, third and fifth. Later levels introduce inversions and seventh chords. Once those feel familiar, try Chord Progression Builder or Harmonize the Melody to put chords into context.
Ready for a different sound?
Mode Learner & Spotter compares modes on the same home note. For example, C Mixolydian changes the B of C major to B♭. Listen to that one change before trying a mixed challenge. For more demanding analysis, Advanced Harmony explores Roman numerals, inversions, suspensions and chromatic chords.
A short practice route
Try five note-reading questions, build one scale and then answer five chord questions. Repeat the skill that caused difficulty rather than moving up immediately. Musical Elements Word Match can help you connect the vocabulary with what you are doing. Teachers can set supported activities as homework using a link with their chosen settings; students return a numerical score and result code.
