What is a chord inversion and how does it help music become powerful and exciting???

It describes the relationship of the lowest notes to the other notes in the chord. For instance, a C-major triad contains the tones C, E, and G; its inversion is determined by which of these tones is the lowest note (or bass note) in the chord.
