should I practice against major chords, minor chords, diminished, dominant,etc…?
I have no idea what exercise or book you are referring to so can not answer this question. My recommendations is you follow the suggestions for practice exercises in the books. These exercises have been developed from over 30 years of teaching and have proven to work very well with students that apply themselves daily. Over time you will work with all types of tonality and musical situations in order to apply your contextual ear training skills to different situations. The important thing is to first know the sound of each note against a key center. As this gains in strength your abilities in the various musical situations will become clearer.
