A triad is a group of three notes having a specific construction and relationship to one another. They are constructed on 3 consecutive lines or three consecutive spaces. Each member of the triad is separated by an interval of a third. The triad is composed of a Root, Third, and Fifth.

All triads have three positions that they can be arranged in. The root, 1st inversion, and 2nd inversion.

Root Position Triad

If the triad root is in the lowest voice then the triad is in Root Position.

1st Inversion Triad

If the third of the triad is in the lowest voice the triad is the 1st inversion.

2nd Inversion Triad

If the 5th of the triad is in the lowest voice, the triad is in the 2nd inversion.
