A triad in root position would have which inversion?

A triad in root position is the most basic form of a triad where the root of the chord is the lowest note. This means that the notes are arranged in such a way that the root is on the bottom, followed by the third and then the fifth of the chord.

Inversions of a triad occur when the order of the notes is changed. In the case of a root position triad, no alterations are made to the positions of the notes; the root remains the lowest note. Thus, it is accurately described as being in root position.

Understanding this concept is foundational in music theory, as recognizing the triad's position helps in both composing and analyzing music. The other options refer to different inversions which rearrange the notes differently. The first inversion has the third as the lowest note, the second inversion has the fifth as the lowest note, and the concept of a third inversion does not apply to triads, as it would relate more to seventh chords. Therefore, identifying the triad as being in root position is essential and correctly captures its fundamental arrangement.
