We have talked about how power chords can create ambiguity in the harmony because you cannot exactly tell if the chord is major or minor. In addition, transforming a diminished triad into a power chord creates a chromatic in the key pitch collection as well as ambiguity in the leading tone.
Besides blurring the lines of major and minor, reducing to power chords can help enforce root movements. Now that the listener cannot rely on whether a major chord moved to a minor chord, vice-verse, or whatever – they have to pay attention to the root movement.
Chords that are a P5 or P4 apart will now have more power in transition. The listener will notice the sol – do pitch movement, even if the chords are not V – I, because the key is not exactly distinguishable due to the power chord harmonization.
This can work to your advantage, or work against it. So, pay attention to where and how you use power chords – especially when you are bouncing between triadic harmony and power chords.
