The B Diminished Triads On Strings 123 & 234

The Bdim Triads

This is a continuation of free lesson blogs:

Major Triads in C on strings 123
Major Triads in C on strings 234.
Minor Triads in C on strings 123
Minor Triads in C on strings 234

Dim triads consist of 2 minor 3rd intervals stacked on top of one another. When you stack 2 minor 3rds (3 fret distances), starting from the note B, you get the notes B, D and F.

Another way to think of this: a dim triad is a minor chord with the 5th down a half step.
The word “diminished” in a chord name, always refers to the 5th that was lowered. (The words “major” and “minor” refer to the 3rd)

Here’s the fingerings for the Bdim triad on strings 123 and on 234.


Play them up and down the guitar neck on both string sets till you have them memorized.
A fun way to practice these chords, is over a G7 1-chord groove backing track. (G7 has the same notes like a Bdim triad: G B D F)
