2nd inversion

Definition

In music theory, 2nd inversion refers to when both the third and fifth of a triad (chord) become higher than its root. This creates an interval of six between the bass note and middle note.

Analogy

Imagine you have three friends standing next to each other in height order. If they switch positions so that now your tallest friend stands in between your two shorter friends, it's like having a triad in 2nd inversion - with both its third and fifth (tallest friends) above its root.
