I'm 5 days away from a major aural test and I still can't even tell the difference between a major and a minor chord. My interval skills are great and I can identify scales quite easily. However I don't know why but its hard for me to grasp and tell the difference between the most basic chords. I do play several instruments and practice spotting the difference between the chords on them frequently. The happy/sad technique doesn't really help me and I find spotting the third a bit of confusing still. I need tips and tools to identify chords desperately! any help would be appreciated.
