Very nice

The app does a good job presenting standard ear training like intervals, chords, etc. But what I really like most is that this is one of the only apps I know of that has so many melodic exercises using actual examples from songs and pieces, not just randomly generated patterns from various scales. This really helps the ear learn sounds and patterns in typical contexts and has helped me a lot with my transcribing even unrelated tunes. I particularly like all of the Bach and the Charlie Parker tunes. Something like this would be a great way to learn jazz (esp. bebop) licks and internalize bebop language. I hope more of these can continue to be added.

Thanks so much for using Chet and for the kind and helpful review. We'd love to hear about any specific content (e.g. composers) that you'd be particularly interested in seeing on the app.

Piano teacher recommends, but fix melodic minor please!

I’m a classically trained piano teacher, I love using this app to improve my own ear and I plan to recommend it to students. I especially appreciate the algorithm which picks up on your weaker points, and gives you opportunities for dialed-in practice where it can tell you’re struggling with a specific concept.

Would give five stars if not for an error in how the app handles melodic minor scales. It plays the descending scale identically to the ascending and it expects you to do the same. ...The correct way to play a descending melodic minor scale is to flatten the 6th and 7th so you’re just playing a natural minor, but the app will ding your score if you actually play it properly - it wants to train you to play the sharp 6 and 7 on the way down as well as up, which is incorrect!

Devs, please let me know if you see this and fix the issue in your otherwise incredible/fun/useful app, and I will add the 5th star posthaste :)

Hey Chai!

Thanks for reaching out. So glad to hear the app is serving you well :)

Currently, the app handles melodic minor in the way most jazz musicians would use it. Some people even call it 'jazz melodic minor' when the descending version is the same as the ascending.

We're going to put some thought into all of this, and try working on a classical version of the melodic minor/harmonic game.

Thanks again!


Hi Chai,

The latest version of Chet now supports classical melodic minor!

Under beginner in the Scales collection, we have two new games, "Harmonic/Melodic Descending (Classical)" and "Harmonic/Melodic Minor [Ascending and Descending] (Classical)". Harmonic/Minor Ascending is the same game for jazz and classical.

Thank you for your suggestion!

My new one-stop shop for ear training!

I teach private music lessons to a diverse client base, and this is going to be my new #1 ear training app recommendation. I just love how it breaks down different options and makes targeted drills easy to find for each learner. I’m sure I will be able to help many different people solve their ear training problems to advance toward their goals with this awesome app. And it works elegantly and looks great. Don’t change a thing!
