## What is Music Theory App?

Music theory lessons as a book you can hear, with a notes teacher, a sight-reading coach and an ear trainer built in. Learn to read music, play piano notes by name, hear every chord, and keep it with music theory games.

Music theory as a book you can hear. One idea per page, and every idea is played: tap the keys, watch the staff, hear the chord, then try it yourself.

BEGINNER
Notes on the keyboard and the staff. Rhythm: beat, note values, bars, counting, dots, ties, sixteenths and 6/8. Scales, key signatures, minor keys and the circle of fifths. Intervals, triads, inversions, the chords in a key and Roman numerals.

INTERMEDIATE
The four loops under most songs, playing in time, and your first eight-bar loop, saved on your device. Seventh chords, chord symbols and colour chords. Modes, pentatonics and the blues. The full progression library and minor-key loops. Cadences, dominants, secondary dominants, modulation and mixture. Writing a melody, embellishing tones, phrase structure. Playing in a band: basslines, groove, the singer's key. Song forms and a complete song sketch.

ADVANCED
Counterpoint, four-part writing, figured bass, six-four chords, sequences, chorales, Neapolitan and augmented sixths, chromatic mediants, analysis, species counterpoint, invention and fugue.

TRAINING
Melody dictation: 120 lessons from two notes in C to any key. Interval trainer with a song for every interval. Sight reading: 120 lessons in time with a click. Rhythm reading: 120 lessons up to tuplets and 7/8. Drills on notes, intervals, chords, scales and progressions, on the staff, on the keyboard and by ear.

TOOLS
Metronome and tuning fork.

No account, no ads, no tracking. Your progress and your loops stay on your device.
