Chords


Chromatic Tetrachord Covers

I recently revisisted this post and decided to smarten up some of the presentation. The idea is to take a common seventh chord and find all the ways to divide up the remaining 8 notes that aren't in it between another common seventh chord and some weird combination of the leftovers.

A few ii-V-I subs for the weekend

I've been messing about with various chord subs and voicings lately. Here are a few things I've been playing. They're mostly based on Coltrane changes, but they're not exactly that. I've written them out with voicings so even if you don't like the sub ideas themselves there might still be something to steal.

Vertical Polytonality

Here's something I picked up from Yusef Lateef's Repository: stacking chords where each voice is from a different scale. Interesting results -- check it out.

Some Modal Ideas on Nefertiti

I've been working on the Wayne Shorter tune "Nefertiti" lately, and have a few ideas for scale superimpositions that sound quite interesting. What I'm presenting here isn't somethng finished; consider it ephemera from the woodshed. I find this quite a useful way to practice a tune with tricky harmony and you might, too.

Minor-Major 7 Arpeggios on Dominant Chords

This is a quick note on a John Stowell video, giving a summary of the idea he describes and then extending it a bit. It's pretty much the same general approach I advocate in my Arpeggio and Scale Resources. Commenters on the video express some confusion about the presentation so I thought it might be helpful to boil it down to a summary and then couldn't resist adding my own twist.

Melodic Minor Quartal Boxes

A while ago I posted some general information about harmonizing chords in fourths. In this post I want to follow up on that, focusing on melodic minor modes in fourths as a way to create surprising voicings and give your chords some harmonic motion.

Meet 3-3, the "Harmonic Minor Trichord"

In a previous post we made a quick survey of the possible trichords according to Forte's classification. Trichord 3-3 (C-Db-E) and 3-3I (C-D#-E) is, I claim, the most interesting of all. This is because it's the only one that isn't found in the major scale except (a) the cluster of two semitones and (b) the augmented triad.

Diatonic Stacks of Seveths

Following up on a previous post grappling with stacks of semitones, here's a quick set of related fingerings. The first two are stacks of sevenths, then we do stacks of ninths, and finally a "bonus" set made by putting a second on top of a ninth.

Unusual Extensions on Major and Minor Seventh Chords

This post collects up some chords I've found by deliberately adding "wrong" (i.e. unexpected) extensions to common seventh chords. The results are often very strange and beautiful, and are sometimes heard in jazz settings such as big band arrangements where you can get away with very crunchy harmonies.

Chord Scales from the Maj Add b13

In my last post I talked about some ideas for using Add 11 chords, and this time I thought it'd be fun to attack another under-appreciated added note: the flat 13.
