Study Music Theory

Anyone can learn music theory. The hard part is learning to HEAR it — and that's what most apps skip.

Study Music Theory teaches you the whole thing, from absolute basics to jazz harmony across 1,496 free lessons, then trains your ear to recognise what you've learned: a gamified ear-training journey, a mic mode that checks the notes you play on your real instrument, and transcription drills that get you reading songs by ear. Learn it, then play it back.

Built for anyone who wants to actually understand music: self-taught musicians, songwriters, producers, singers, instrumentalists learning their first scales, and experienced players filling gaps in their theory.

━━ WHAT'S INSIDE ━━

• 1,496 lessons across 12 carefully-structured levels
• Level 1: Absolute basics — what sound is, how we write it down
• Level 2: Rhythm, time signatures, note values
• Level 3–4: Scales and intervals
• Level 5–6: Chord construction and progressions
• Level 7–8: Functional harmony and modulation
• Level 9–10: Modes, pentatonics, and blues
• Level 11–12: Jazz harmony, voice leading, reharmonization

━━ KEY FEATURES ━━

👂 A COMPLETE EAR-TRAINING JOURNEY
Not a wall of quizzes — a gamified journey across a constellation "sky map" you light up as you master each skill. Earn stars, keep your streak, and climb from rest-and-tension all the way to transcribing chord changes by ear. It trains reasoning, not guessing: every answer plays the resolution and shows you why.

🎤 PLAY IT BACK — ON YOUR REAL INSTRUMENT
Hear a note or phrase, then play it back on your real guitar, bass, piano, ukulele, or voice. Studio-grade pitch detection listens and a live tuner shows exactly how close you are. The closest thing to real musicianship in an app.

🎼 TRANSCRIBE, COACH & DRILL
Rebuild riffs by ear on a playable keyboard, get an adaptive coach that targets your weak spots, and drill chord progressions in any key — plus interval, chord-quality and scale ear tests woven through the course.

🎹 THEORY YOU CAN HEAR & TOUCH
1,496 lessons from first principles to jazz reharmonization. Tap any note, chord, scale or progression to hear it and see it on the keyboard — learn by doing, not memorizing. Pure synthesis, works instantly.

📊 QUIZZES & XP PROGRESSION
Every lesson ends with a quiz. Earn XP, level up, unlock medals. Spaced-repetition review keeps older material fresh.

🔥 DAILY STREAKS
Build a learning habit. Track your longest streak. See your progress build day by day.

📶 WORKS OFFLINE (AFTER FIRST LAUNCH)
Lessons cache automatically on first launch. After that, practice on the tube, on a plane, anywhere you want.

🎨 CLEAN, FOCUSED DESIGN
No clutter. No ads. Warm, readable typography. Dark mode. Built by a real music student, not a committee.

━━ WHO IT'S FOR ━━

• Self-taught guitarists who want to understand what they're playing
• Singers learning to read charts
• Songwriters who want to escape the three-chord trap
• Producers and beatmakers who need functional harmony
• Students prepping for ABRSM, Trinity, AP Music Theory, or grade exams
• Anyone who always meant to "learn theory properly"

━━ WHAT IT'S NOT ━━

Not an instrument tutor — it teaches the concepts, not how to play. Pair it with your preferred instrument app for the full picture.

Not a sheet-music reader. We cover notation thoroughly but don't turn you into a sight-reading machine.
