Quick Theory

Quick Theory teaches real music theory the way a friendly teacher would: one small idea at a time, with your hands on the answers. TYPE THE MUSIC No instrument needed. You answer with a letter keyboard โ€” A to G, sharps and flats โ€” and quick taps. The piano on screen is your teacher's piano: it plays and shows, you listen and spell. EIGHT COURSES THAT ADD UP โ€ข Introduction to Music Theory โ€” the twelve notes through scales, keys, intervals, chords and progressions โ€ข Introduction to Music Theory, Part Two โ€” minor for real, pentatonics and blues, inversions, sevenths and cadences โ€ข Reading Rhythm โ€” note values, time signatures, and counting that sticks โ€ข Ear Training, Part One โ€” from "up, down or same" to hearing a melody's shape and finding home โ€ข Chords by Ear โ€” scale degrees, chord colors, bass lines and cadences โ€ข Advanced Chord Construction โ€” build any chord in any key, decode any symbol on a chart โ€ข Guitar Theory, Part One โ€” the fretboard map, CAGED, barre chords, and your first improv map โ€ข Songwriting โ€” verses, choruses, hooks, prosody, and finishing the song EAR TRAINING DRILLS Six configurable drills that build the ear behind the theory: Interval Recognition, Melodic Dictation, Chord Progressions, Chord Qualities, Scale Degrees, and Meter Detection. Set the range, the speed, and the answer surface โ€” solfรจge or piano โ€” and practice exactly what you're weak at. A TOOLKIT THAT COMES WITH IT Look anything up: Chords, Scales & Progressions, Circle of Fifths, Scale Fingerings, Alternate Tunings. Practice with a Tuner & Pitch Pipe, Metronome, Slow Downer, Piano, Sight Reading, Random Note, and Jam Along โ€” a band that loops while you play over it. Write with Lyric Studio, Melody Helper, Riff Recorder, and Tab Studio, a full guitar tab writer that plays back and exports. MISTAKES ARE PART OF THE PLAN Wrong answers get real explanations โ€” not just "incorrect." Miss the same idea twice and the app changes how it asks. Genuinely stuck? The lesson steps aside, tomorrow it invites you back, and nothing guilt-trips you in between. SPELLING COUNTS A-sharp and B-flat share a piano key but mean different things. Quick Theory is the rare app that teaches you why, gently, at exactly the moment it matters. MADE TO RESPECT YOU No account. No ads. No tracking. Lessons and tools work offline, and your progress, songs, lyrics and recordings sync through your own private iCloud โ€” only you can reach them. Speed Rounds review what you've learned, a Weak Spots quiz targets what you keep missing, and a lenient streak celebrates showing up and forgives a missed day. Whether you sing, play, produce, or just want to finally understand what "the key of F major" means, Quick Theory gets you there a few minutes at a time.
