1st inversion

Definition

In music theory, 1st inversion refers to when the third of a triad (chord) becomes its lowest note. 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 shortest friend stands in between your two taller friends, it's like having a triad in 1st inversion - with its third (shortest friend) at its lowest position.
