This is a hard one. One thing that helped me is to realize that Csus2(C-D-G) has the same notes as Gsus4(G-C-D). Csus2 is really the first inversion of Gsus4. This means that we have to pay attention to the relative octaves as well, when we take apart the notes. Hope this helps.

I'm still confused with those Sus chords. It is so hard! @@

the problem might be that you are flipping the notes. c-f-g- is sus 4, but f-g-c is sus 2. Hearing where the M2 is ( f-g in this case) and listening if there is a note beneath that helps me, maybe it will help you.

I use The Force and still only get it right half the time

Wasup Ray Z,

My personal suggestion would be to understand how they relate to the major chord. Although they have similar chord qualities, and are interchangeable with their closest circle of fifths neighbor, they suspend two different resolution notes (the 3rd in sus4; the root in sus2).

Once you get a grasp of where the suspended note wants to resolve to, you'll better understand how different they sound.

To my ears, the sus4 is much more subtle and embelished, way more pulling to resolution, very often used in music to add a little tension to a section's final chord. Whereas the sus2 is just interesting, very stable by itself but also a little mysterious and sparking curiosity, giving you a sense of indetermination, it doesn't really pull to resolution as the sus4 does.

These are tough, I will say on chordelius ot helped me to use the compare after you get them wrong to help you tell the difference.

What Sebastian mentioned was my problem, I was getting the notes right but not in the right order. Also, hearing the character was tough for me, but eventually a combination of listening for character/figuring out what notes were in the chord got me past those levels in chordelius.

I get them 90% of the time wrong. Cannot for the sake of my life and the life of my children to figure that one out.

I would say get familiar with the sound of a M2 and P4 against its root. The better you get at hearing those, start to add M2 and P4 against its root and major 3rd.

I break things up into smaller chunks if the whole is to difficult.

Hey, I used to get them always wrong, but after a while never anymore. Maybe you could attempt to just practice these two to tell them apart? It's mostly what happens with every interval, we all struggle with one or the other.

I just realized that one of the reasons I was getting them wrong is because I was hearing the sus2 as wanting to resolve down (for instance I was hearing Csus2 (C D G) wanting to resolve down to G/B (B D G). Every time I heard a sus2 I would mark it as sus4 because sus4's resolve down, but really, I was 'resolving' the wrong note. Maybe that helps.
