Diminished Harmony Secrets: Expand Your Diminished Harmony Vocabulary Infinitely

About this masterclass
Jake Reichbart teaches a methodical system for generating a virtually limitless supply of diminished-scale voicings for dominant 7th chords. Most players know the trick of moving a diminished chord up the neck in minor thirds as a 7♭9 substitute — this lesson goes far beyond that, showing how to organize the half-whole diminished scale into hundreds of usable chord shapes.
What's covered
- Why the half-whole diminished scale has no avoid notes against a dominant 7th: it yields the 1, ♭9, ♯9, 3, ♯11, 5, 13, and ♭7
- The scale's symmetry — how moving any note by a minor third lands on another scale tone
- Building an initial four-note voicing on the top four strings (demonstrated over an A7 root)
- Moving that voicing in minor thirds, including the often-neglected "in-between" voicings, to create a complete series of eight scale-chords
- Inverting the voicing to produce three additional fingerings, then running those through the same minor-third cycle
- How to break out of the box afterward: three- and two-note versions, other string groups, rootless voicings
Because any combination of these eight notes works against the root, the only limit is your own taste. Regardless of your level, you will come away from this lesson with new chord voicings you can use right away. A download is included with the full class.

"Very useful"
Thanks, Jake! I enjoyed this lesson and put the ideas to work right away!
"Excellent information"
This is a really interesting class showing possibilities with diminished chords. Jake gives a well presented and organized class. It gives me some very interesting and modern sounding chords and a system I can use to come up with my own application of his concept. I'll be working on this concept for daily. Just what I was looking for to expand my harmonic sound.
