## What is 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 — A to G, sharps and flats — 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
• Introduction to Music Theory — the twelve notes through scales, keys, intervals, chords and progressions
• Introduction to Music Theory, Part Two — minor for real, pentatonics and blues, inversions, sevenths and cadences
• Reading Rhythm — note values, time signatures, and counting that sticks
• Ear Training, Part One — from "up, down or same" to hearing a melody's shape and finding home
• Chords by Ear — scale degrees, chord colors, bass lines and cadences
• Advanced Chord Construction — build any chord in any key, decode any symbol on a chart
• Guitar Theory, Part One — the fretboard map, CAGED, barre chords, and your first improv map
• Songwriting — 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 — solfège or piano — 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 — 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 — 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 — 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.

## Version history (last 2 releases)

### 1.3 — 2026-08-18

Ear Training — a whole new section

Six drills, each fully configurable, from the Ear Training card on Home:
• Interval Recognition — 12 intervals, ascending, descending or harmonic, with range and speed dials
• Melodic Dictation — 2 to 15 notes, answered on solfège or piano, with cadence and tonic toggles
• Chord Progressions — build what you hear from a palette that includes borrowed chords
• Chord Qualities — the full 31-quality catalog, harmonic, arpeggiated or mixed
• Scale Degrees — a cadence, then the mystery note, in major or minor
• Meter Detection — simple, compound and odd meters, on drum grooves and melodies

Tab Studio

A guitar tab writer in Songwriting Tools: write and edit tab, hear it back, and export to PDF, text tab or audio.

Better idea capture

Riff Recorder never loses a take — a rehearsal buffer catches what you played before you hit record. One-tap tags, a 10-second undo on delete, and new capture widgets to start a take from your Home Screen.
