In a triad, what is the term for the 5th inversion?

In music theory, when discussing triads, each inversion refers to a specific rearrangement of the notes in relation to the bass note. In a triad, there are three primary positions based on which note is the lowest:

1. Root Position – This is when the root of the triad is the lowest note.

2. 1st Inversion – In this case, the third of the triad is the lowest note.

3. 2nd Inversion – Here, the fifth of the triad becomes the lowest note.

As for inversions, there are only three for a triad (root position, first inversion, and second inversion). The concept of a "5th inversion" typically does not apply to triads because they only have these three distinct positions. Therefore, labeling the root position as the 5th inversion is incorrect in a traditional context, as there isn't a 5th inversion for a triad.

The information provided suggests that the answer provided, labeling it as root position, may have misrepresented how inversions are numbered. The accurate identification is that root position is indeed the foundational state of a triad and is not an inversion but the original arrangement of the notes.
