Here we discuss using the diminished triad in 4-part or 4-voice (soprano, alto, tenor, bass) writing. Since the diminished triad has only 3 different notes, but there are 4 different voice parts, one of them will need to be doubled. Diminished triads frequently appear in 1st inversion (where the 3rd is in the bass). The "rule" for this scenario is as follows:

• When the Root or 3rd is in the Soprano, double the 3rd (in the bass)
• When the 5th is in the Soprano, double the 5th (in the Soprano)

It's really less complicated than it at first sounds! Watch the video and you'll see :)

Although the video refers to specific examples found in a standard harmony text, what is presented here may be applied universally.
