About this masterclass
Jazz guitarist Roni Ben-Hur takes a deep look at the diminished chord — a chord that always wants to take you somewhere — and shows how to move it beyond its basic passing-chord role into a colorful harmonic device for comping and chord-melody playing.
What's covered
- The structure of the diminished chord as a cycle of minor thirds — why every note can be the root, and why there are really only three diminished chords
- Using the diminished as a leading chord, demonstrated through standards like "What's New" and "Spring Is Here"
- The relationship between diminished chords and dominant 7th chords, and converting between them with a half-step technique
- Instant chord inversions and substitutions on the fretboard that fall out of the minor-third cycle
- Adding colors and tensions beyond the plain diminished sound, including flat 9 extensions and borrowed notes
- The exceptions — when not to use diminished substitutions over IV and II dominants
Roni notes that a thorough explanation of diminished theory also appears in his book Talk Jazz, but the class builds from a clear introduction into more advanced material. A practical course for intermediate players who want to add depth to their chord progressions and apply these voicings tastefully in real tunes. Includes a Soundslice example on using the diminished with one borrowed note.

Great lesson on diminished, very detailed. Maybe sometimes a bit too repetitious. It would be even better if there was a backing track. But overall an indepth analysis of the use of the functional diminished chord.
