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.

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!

Too Predictable

Ive enjoyed the app and it is definitely helpful and easy to use. However, i ran into a rather disappointing bug in the game. In the “intervals” games there are typically 2 options (minor, major). I’ve noticed that the answers are a predictable pattern in which the answer just alternates between major and minor every turn. If the answer to question 1 is major then 2 will be minor, 3 is major, 4 is minor and so on. It can be possible to ignore this fact but sometimes it’s just too obvious and takes away from the challenge and learning process of the game. I can imagine this should be able to be fixed.

Thanks for pointing this out! It has been fixed in Version 2020.4 which has just been released.
