Simply be receptive to the sound-feeling of each chord as a whole with respect to the key center.
Learning to associate the theory and sound-feelings of chord changes with music that you've heard before is a great way to develop your aural awareness. Here are some examples of this chord change in action:
Singing out loud is a very effective way to get musical sounds into your mind’s ear. Singing is an active process that excites many sensory and memory and motor pathways in your brain. This broad-based activation leads to much faster and deeper learning than passive listening alone. Sing out loud, while associating each sound with something you already know.... notes in written music or keys on the keyboard.
Always be sensitive to how each and every note sounds and feels with respect to the key center Do.
Very Important: It is absolutely essential that you sing all of these studies out loud and at your own pace, a pace that allows you to sustain each note long enough to make an impression on your mind's ear! If you can't sing them, you don't know them!
Notice the very strong attraction that the note B (Ti) has for C (Do). For this reason, Ti is often called the leading tone. It leads the ear back home to the tonic (Do).
Notice that the note G (So) is common to both chords, so has no need to resolve.
