Bdim Triads on The Bass Strings.
For the new shapes we are covering today, you are basically using the shapes as covered in this blog, Minor Triads On The Bass Strings, and you lower the 5th of the chord down a half step to make it diminished.
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 the bass strings.
- The fingering on frets 14/12/10 is root position.(B D F)
- The fingering on frets 5/3/4 is 1st inversion. (D F B)
- The fingering on frets 8/9/7 is 2nd inversion. (F B D)
Learn the Bdim fingerings on the A, D and G strings first.
Play them up and down the guitar neck 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)
Then start this process over again on the lowest 3 strings.
Good news: this won’t take too long, because all shapes are exactly the same as on the previous (A, D and G) string set.
You already know the shapes, you just have to get their locations memorized on this last stringset.
