Learn the Bdim Triads on The Bass Strings.

Bdim Triads on The Bass Strings.

This is a continuation from following free lesson blogs:
Minor Triads On The Bass Strings.
Major Triads On The Bass Strings.
Bdim Triads on Top 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 are the fingerings for the Bdim triad on the bass strings.


  1. The fingering on frets 14/12/10 is root position.(B D F)
  2. The fingering on frets 5/3/4 is 1st inversion. (D F B)
  3. 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 as 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 string set.

These free lessons are cool, but you will never experience the progress, joy, and results that my students experience in lessons when you’re learning by yourself from blogs and videos.

That is why people take lessons: way better results and progress, much more complete information, exposed to way more creative ideas than you can get from a blog or YouTube video.
There is only so much that self-study can accomplish.

If you want to see amazing results and progress in your guitar playing, buy your first lesson here and get started ASAP.
