✦ AI summary

Players praise the game as a useful, affordable ear training tool that effectively helps musicians learn chord recognition and structure, particularly beneficial for beginners and those learning instruments like ukulele. However, common criticisms include occasional incorrect answers, limited difficulty progression that becomes too easy for intermediate players, and tedious mechanics like full tier resets from single mistakes, with some feeling the price isn't justified and wishing for more advanced features like chord progressions and interval recognition to extend its usefulness.

It is a fun educational game for those who play musical instruments. In a casual/puzzle mode you can test and train your ears to recognize chords.

This helps me build chords without looking up charts on ukulele. It's especially useful because ukulele has a lot of inverted notes in chords which the game has practice for. You listen to the key of the music in the background to figure out what key you're in then you cut the string that causes dissonance in the chord. The difficulty goes from absolute beginner to challenging even if you study music theory. If you're good at music theory there isn't a lot of competition in the leaderboards, if you're still learning music this is a great learning tool.

Boring and wrong. This is my 3rd try for this game. Just failed a question where Eminor was implied but still had the the major 3 as a option.

I wouldn't say this is worth 9 dollars.

For £6 this game is very worthwhile, for me. I do hope the dev continues to develop this game. In its current form, it is probably best suited to those who've just started on the musical path in some form. I found the first few tiers (basic major and minor chords) very easy, but it helped to reinforce my shaky knowledge of chord structure. For me, things got much more challenging when it started introducing seven strings, with 7th chord inversions. With 8 strings, I found it tedious when you get most of the tier correct but then have to restart the tier because of one mistake. Still, it seems a good-value ear training program, suited to budding musicians.

Pretty good game. Only downside is that it isn't hard at all. So the ammount of ear training you can achieve is limited. I would've the devs add chord progressions, chord inversions (that you must identify) and borrowed chords to make it more interesting and useful. I guess there are apps for mobile that do that, but a game on steam - with achievements and all that jazz - that had these features would be really great. And if anyone decides to do that, add interval recognition, melodic dictation, rythmic dictation and dodecaphonic series dictation to make it a very thorough ear training game. Overal, if you're a beginner this will be a good start to getting your ears trained. Just make sure to pair it with interval recognition training to accelerate your ear development.
