Tonalia: Music Theory by Ear
Chord Progression Ear Training
Only for iPhone
Free · In‑App Purchases
iPhone
Hear harmony before you name it. Five minute lessons in intervals, chords, modes and voice leading, and a piano that plays every answer.
Learn music theory by ear, five minutes at a time.
Tonalia teaches harmony the way musicians use it. You hear a chord, a cadence or a progression, then you name it, build it or find where it goes next. Every exercise plays. Nothing on screen is a dead label.
LEARN
Six sections and 78 skills, in short lessons of twelve questions.
• One key: intervals, triads, the diatonic chords, cadences and sevenths. Free forever.
• Minor and mixture: the three minors, secondary dominants and borrowed chords.
• Modes: the seven modes of major, plus the melodic and harmonic minor modes.
• Extensions: ninths, elevenths, thirteenths, alterations, shell voicings and tritone substitution.
• Voice leading and modulation: move one voice at a time, find pivot chords, plan a route between keys.
• Arrangement: drop 2 voicings, register, reharmonisation and bass motion.
Eight kinds of exercise: identify by ear, build, name, function, complete, compare, route and explain. Spaced review brings back what you are about to forget, and a placement test lets you skip what you already know.
A DAILY HABIT
A streak and a daily goal of one to three lessons. XP for every answer you get right first time. Five hearts that refill on a clock, and confetti when a lesson is done. A small music note keeps you company: it hops when the app plays a sound and bounces on the beat.
EXPLORE
Four lenses on the same harmonic engine.
• Harmony: the chords around the one you are playing, grouped by what they do, with secondary, borrowed and substitute moves.
• Modes: compare modes by brightness and hear the notes that define each one.
• Extensions: which tensions sit well over a chord and which notes to avoid.
• Arrangements: four voices, and how each one moves from chord to chord.
Sketch a progression, play it back, and export it as an image.
RIGHT, NOT JUST PLAUSIBLE
Exercises are generated by a music theory engine rather than written by hand, so there are thousands of them, and every answer is worked out from the notes themselves.
