Diminished triad chords (dim) | Guitar diagrams & voicing charts

Chord formulas chartIn music, a triad chord is a combination of three notes played all at once. It is built by stacking a root, a third (major or minor), and a fifth (perfect, diminished or augmented). Triads come in different varieties such as major, minor, augmented, and diminished. Here are the four main qualities :

  • Major triad : root (1) - major third (3) and perfect fifth (5).
  • Minor triad : root (1) - minor third (b3) and perfect fifth (5).
  • Diminished triad : root (1) - minor third (b3) and diminished fifth (b5).
  • Augmented triad : root (1) - major third (3) and augmented fifth (#5).

Triad symbols

  • Major triad : Generally, no quality symbol is added.
  • Minor triad :"m" or "min".
  • Diminished triad : "dim" or a degree sign "°".
  • Augmented triad : "aug" or a plus sign "+".

Diminished triad chords | Guitar diagrams, root positions and inversions.

In this lesson, we will see how to play diminished triad chords on the guitar. A diminished triad is made up of a root (1), a minor third (b3) and a diminished fifth (b5). That is to say that it is a minor triad with a lowered fifth. Here is a comparison with the locrian mode. By taking the first, minor third and the diminished fifth of this mode, we get a diminished triad.

Root positions and inversions

Before starting to learn and play the 12 diminished triad chords below, you need to know what is an inverted chord. This is simply a chord whose notes has been arranged in a different order. In other words, you will play the same notes as the root chord, but with the third or the fifth in the bass instead of the root.

Closed guitar chords are those where the positions, fit within the space of one octave. There are 12 closed guitar chords diagrams below divided into 4 categories :

  1. Triad chords with basses on the 6th string.
  2. Basses on the 5th string.
  3. Basses on the 4th string.
  4. Basses on the 3rd string.

Each category contains 1 root position and 2 inverted chords. The chart below shows you the diminished triad voicings related to the chords of each category.

Root position  R b3 b5
1st inversion (third in the bass) b3 b5 R
2nd inversion (fifth in the bass) b5 R b3
