## What is Music Theory & Ear Training?

Learn music theory from absolute zero, then train your ear until you can HEAR it - intervals, chords, progressions and keys. One app takes you from "what is a note?" all the way to working out real music by ear.

THE FULL COURSE — 1,496 INTERACTIVE LESSONS
A complete music theory course in bite-size steps: 12 levels, 173 units, zero knowledge assumed.
• Notes, scales, keys, intervals, chords, harmony, rhythm, jazz and more
• Every lesson PLAYS OUT LOUD - tap the piano keys and hear every example
• Real notation, step by step: treble clef, bass clef, rhythms, key signatures
• Interactive diagrams you can touch: the circle of fifths, chord builders, rhythm grids
• Learning piano or guitar? Lessons show real chord shapes and fretboard maps too

EAR TRAINER — A GUIDED JOURNEY
Not random drills: a 24-chapter path across the night sky, from your first notes to full transcription.
• Hear where notes want to resolve, name intervals, recognise chords and cadences
• Learn to PREDICT the next chord - the skill behind playing by ear
• Every answer comes with a why, so you understand what you heard
• Collect stars, keep your streak, unlock the next chapter

PLAY IT BACK — THE REAL SKILL
• Transcribe: hear a looping riff and tap it back, note by note
• Play It Back: hear a note, play it on your REAL instrument - the mic checks your pitch (guitar, piano or voice)
• Slow it down, loop it, reveal it - work like a real musician

A COACH THAT KNOWS YOUR WEAK SPOTS
The adaptive coach tracks every skill separately and builds each session around what YOU find hard, with spaced repetition so nothing fades away.

STAY MOTIVATED
• Daily streaks, XP, levels and a weekly leaderboard
• One streak across everything - lessons and ear training both count
• Unlock new instrument sounds as you level up

WORKS FOR ANY MUSICIAN
Piano and guitar built in everywhere. Singers, producers and other instrumentalists welcome - theory is theory, and the ear training works for everyone.

FREE, NO ADS
The whole course and every trainer, free. No ads, no lesson paywalls. An optional account backs up your progress and puts you on the leaderboard.

Whether you're picking up your first instrument, writing your own songs, prepping for a theory exam, or you've played for years and want to finally play by ear - start at your level and build for a few minutes a day.


## Version history (last 5 releases)

### 1.0.39 — 2026-08-05

A full content pass over the whole course. Every lesson was re-checked note by note - quiz answers, keyboard and fretboard diagrams, audio demos and song references - and hundreds of corrections were made across all 12 levels. Highlights: mode lessons now show the note that actually defines the mode, key-change exercises accept the right tonic, several answer keys that contradicted their own explanation were corrected, and wrong-note demos were re-recorded. Ear-training tunes were also corrected.

### 1.0.38 — 2026-08-04

Bug fixes and stability improvements: lesson crash fixed, offline start-up fixed, audio polish.

### 1.0.37 — 2026-07-28

Bug fixes and improvements.

### 1.0.36 — 2026-07-18

Weekly leagues: earn XP to join a room of 10 and climb 200 leagues. Smarter transcription practice that repeats only what you miss. Premium introduced with a generous free tier - 3 new lessons every day, and everything you've completed stays free forever.

### 1.0.34 — 2026-07-15

Fixed: answers in the unit mastery quizzes (the sword icon at the end of each lesson cluster) could not be tapped after finishing a lesson. They now register correctly.

Also: if you've been learning with us for a while, you may see a short prompt asking you to rate the app. It only appears after a good session, and you can dismiss it for good.
