My favorite ear training app
Best ear training app out there. You can play in piano and guitar mode which I find really helpful as a multi-instrumentalist. Excellent in-context musical examples from real songs recorded by great musicians. Can't recommend more highly!

Brilliant
This is a simply great app - it’s very motivating to do a few minutes of practice a day and see your stats and skills improve. The whole experience is a lot more polished and deep than you might expect from a free app. Bravo!

What is Chet?

Chet is an ear training and music theory app for musicians of all levels. You can compete with other musicians to achieve high scores or play at your own pace in a wide variety of games.

What are the two sections of Chet and how do they work?

Chet has two sections: Learn and Practice.

In Learn, Chet guides you through a learning path called Foundations. To move ahead you need to earn at least one star per game. If any part of the path feels too easy, you can skip units by passing one of the 'Jump Ahead' tests.

In Practice, you can work on your own on topics like intervals, scales, and tunes, in timed or untimed games. Timed games give you around 60 or 90 seconds to answer as many questions as you can.

Each collection in Practice also starts with a fluency game, a timed test of your overall skill. Each mistake gives you a strike, and the game ends after three strikes or when time runs out.

Where should I start on Chet?

If you are a beginner, or have little or no experience with ear training and music theory, we recommend starting in Learn. Once you’ve made some progress, try some beginner games in Practice.

If you are an intermediate player, with a fair amount of ear training and music theory experience, we recommend starting in Practice. If you prefer guided practice, start in Learn and pass a 'Jump Ahead' test to skip to Unit 3 or 4. To test your overall fluency, try the fluency game at the top of each collection.

If you are an advanced or professional musician, we also recommend starting in Practice and trying the fluency games.

What is ear training and why should I focus on it?

Ear training is the practice of identifying musical concepts, like melodies, scales, and chords, solely through listening. Musicians train their ears because it strengthens the connection they have with their instruments. A musician with a trained ear can easily play back a melody that they hear. They can also improvise over a chord progression they've never heard before, or imagine a melody inside their head and play it on their instrument. By working on ear training, you will vastly improve your skills not only on your instrument, but also in music theory, composition, and improvisation.

What are the different collections in Practice?

The collections in Practice are:

Tonal: Melodies based on the major and minor scales
Scale Degrees: Identifying single notes in different keys
Tunes: Famous melodies from real music, performed by world-class artists
Scales: Ordered sequences of notes
Arpeggios & Chords: Three or more notes played one at a time or together
Intervals: The distance between two notes
Progressions: Multiple chords played in succession
Atonal: Random sequences of notes
Theory In Context: Applying music theory to real music
