What position/inversion is represented by a triad's 6?

When a triad is in its 6th position, it indicates that it is in second inversion. In music theory, triads consist of three notes: the root, the third, and the fifth. These notes can be arranged in different positions depending on which note is the lowest in pitch.

In root position, the root of the triad is the lowest note. In first inversion, the third of the triad becomes the lowest note, which then creates the interval of a 6th above the bass note. In second inversion, which is represented by the number 6, the fifth of the triad is the lowest note, resulting in a 6th interval from the bass note up to the root of the triad.

Therefore, when the triad is in second inversion, it means that the fifth of the triad is in the bass while the other two notes are positioned above it. This configuration has specific harmonic implications, often used in chord progressions to create a specific movement, especially in the context of resolving to a more stable chord.
