In this article, you’ll learn how to construct the G sharp diminished triad as well as how to play it on piano and guitar.
We’ve also included sections on inversions for those that want a deeper understanding. Lastly, listen to some examples of popular songs that featured this triad.
Root, Flat 3rd and Flat 5th
The G sharp dim triad is formed of the 1st, flat 3rd and flat 5th of the G sharp major scale.
- G# – root note
- B – Minor 3rd above the root
- D – diminished 5th above the root
Here is the triad written on the stave in the treble and bass clef.
Before you read on make sure that you have a basic understanding of intervals. Intervals are vital for understanding how triads are built. Check out our guide to major, minor and perfect intervals for more on this.
G# dim Triad on Piano
Below you can see how to play this triad on the keyboard or piano. This pattern of notes could also be played starting on any G sharp note.
However, the order of the notes must be the same:
- G# – root note (lowest note)
- B – min 3rd (middle note)
- D – dim 5th (highest note)
This is called ‘root position’.
G# dim Triad on Guitar
There are two simple positions that you can use to play a G# diminished chord on guitar. Both positions can also be slide up or down the neck to play different diminished triads.
1st Inversion
A 1st inversion is where we take a triad but we start on the second note, which in this case is B natural. We still keep the D above, but then the G# (or root) become the highest note.
- B – min 3rd (lowest note)
- D – dim 5th (middle note)
- G# – root note (highest note)
This way of rearranging a triad gives us a different sound as the relative pitches of the three notes has changed.
1st inversion on Piano
On the piano we can play the 1st inversion of a G# diminished chord by starting on a B. They play the D above and the G sharp above this.
1st Inversion of Guitar
Below are the most common shapes for playing a G# dim chord in the 1st inversion. Remember that we can only use certain shapes are the pitches of the three notes are important.
2nd Inversion
A 2nd inversion is where we take a triad but we start on the third note, which in this case is D. We still keep the G sharp above this as we did from the 1st inversion. Then the B becomes the highest note in the chord.
- D – dim 5th (lowest note)
- G# – root note (middle note)
- B – min 3rd (highest note)
We could construct a 2nd inversion starting on any D note in any octave. The only thing that must stay the same is that the we use the G sharp above and the B above that. Below you can see this triad on the staff.
2nd inversion on Piano
On the piano we can play the 2nd inversion of a G# diminished triad by starting on a D. They play the G# above and the B above this.
2nd Inversion of Guitar
Below are the most common shapes for playing a G sharp diminished chord in the 2nd inversion. Remember that we can only use certain shapes are the pitches of the three notes are important.
