Ddim Ab D F

Same chord, different bottom note

The notes never change, only their order. With F or Ab at the bottom, Ddim sounds lighter and lets the melody note on top change.

Tense and unstable: it wants to move to the next chord.

Ddim on each string set

Start with the top three strings: the shapes are small and the top note is clear. Then move the same idea to the lower sets.

How to move between the shapes

On the G-B-e strings, the shapes go up the neck in this order: 2nd inversion (fret 3) → root position (fret 7) → 1st inversion (fret 10). The top notes along the way are F, Ab, D.

One area of the neck, near fret 8, already holds four Ddim shapes: G-B-e strings 7-6-4; D-G-B strings 6-7-6; A-D-G strings 8-6-7; E-A-D strings 10-8-6.

Frets from the low E string to the high E string; x = string not played.

Make Ddim triads automatic

  1. Start with the G-B-e strings only: three shapes, one minute each.
  2. Climb the neck through the three shapes and come back down without stopping.
  3. Stay near fret 8 and find Ddim on two different string sets.
  4. Then test yourself: random chord names, find the closest Ddim shape each time.

Small daily sessions work best: shapes stick by repetition.

Common questions

How do you play Ddim triads on the top strings?

On the G, B and high E strings: 2nd inversion 1-3-1; Root position 7-6-4; 1st inversion 10-9-10. Play only those three strings.

Why learn triad inversions on guitar?

They let you play Ddim in any area of the neck with three fingers, so chord changes stay close and the top note can follow a melody.

What does a Ddim triad sound like?

Tense and unstable: it wants to move to the next chord.

Can I practise Ddim with a game that listens to my guitar?

Yes. ChordRunner hears your guitar through the microphone and checks the chord in any shape or inversion. A USB MIDI keyboard works too.

Your instrument is the controller.

ChordRunner is a browser game that teaches piano and guitar chords: a chord appears on screen, you play it on a real instrument, and your runner jumps. MIDI keyboard or microphone, both work.
