I have 42 level at Chordelius, I do not hear or listen to individual notes, rather the characteristic of its mood. Like 7 chords are bluesy, diminished are like 7 but lack fullness, sus4 and maj7 are very synthwavey to my ear, and so on. In fact I find Chordelius the easiest game here

I'm level 44, but I struggled to get there. I tried to hear the tonality, but then I changed to finding the individual notes, which helped me hearing the tonality over time.

So if you struggle, I think trying to hear the individual notes in the beginning is the way to recognising them by tonality.

And if you're not doing it already, try singing them out loud. It's hard at first, but after some time you'll break the code.

I'm at level 74 but I find this one of the hardest games for me. I try to listen for intervals - is there a minor third, a tritone, 2 major thirds, etc. I'm now using random instruments, so that has made it a little harder at present. Just have to stick with it!

I am 54, I mostly listen to the quality of the chord, this worked for Maj, min, dim, aug, sus 2/4, maj/min add 9 and the seven chords. For sixes, I have needed to start listening to the intervals, and in that transition I lost a lot of steam. In the end I took a six month break back at level 49 and just started playing it again. I mostly progressed because of a bit of luck, and practicing chords on Olympics.

hey try to practice daily all kinds of interval exercises plus this one. one thing that helped me a lot was stopping to watch the answers so the reflexion process is much harder since you have to choose between all the chords you've seen and not only a few. other ppl on this thread are right tho. Go on and enjoy the process

what i do (if i can't immediately identify): listen for the main quality of the chord (major, minor, or sus & perfect or altered fifth) then try to listen to the extensions. you should use the pause/review tool (bottom right) after every answer and sound out the arpeggios yourself. I also play the arpeggios on my bass after each answer.

the goal is to be able to quickly identify a chord, so you don't need to ''hear'' each individual note. if you can identify the chord you already know every note in the chord. the same way as a proficient reader doesn't sound out every syllable in their head.

again, it helps to take time after you answer to sing and play the notes. even on ones you get right. I've found using my instrument to reinforce my answers to be very helpful

I think the difficulty stops increasing at around level 120. I am at 314 and it still feels that i'm not 100% confident at this, although I'm slowly getting better at chords contest.

In the beginning, I used a combination of technical skills to identify the chords, mostly revolving around chord function in a progression and how they resolve. But with time it just becomes a really strong intuition so you immediately know what is what. If you are having problems with any specific chords I suggest to spend as much time on figuring out what is it unique about it on the fundamental level (intervals, functions, etc) otherwise your intuition will have nothing to latch on to.
