Kyoto Live Series: The Missing Ones

If you are in Kyoto in November…

Experience the thrill, shock and novelty of improvised music with The Missing Ones, in Kyoto, Japan.

We kick off the Kyoto Live Series with our first show at UrBANGUILD, on 11/8; free entry, shows at 7:30pm and 9pm.

The Missing Ones are Dan Cosley on guitar, Dave Moss on bass, and Patrick Golden on drums. The UrBANGUILD and Zac Baran shows will feature Andy Couzens on synths and electronics, and Video art by [sic]).

Two New Books!

Three & Four-Note Chord Compendiums: Permutation-Based Harmony Workbooks for Guitarists

I’m excited to announce the publication of two new books, both available worldwide on Amazon.com!

Three & Four-Note Chord Compendiums: Permutation-Based Harmony Workbooks for Guitarists

The Four-Note Chord Compendium is the first mathematically-complete book on four-part guitar harmony ever published. 

Nearly 400 pages in length, it contains 5,535 unique chord forms for analysis and exploration: every possible combination of four notes on the instrument.

Also included: suggestions for fingerings, practice approach, and harmonic analysis.

An all-encompassing encyclopedic text, and an essential part of every guitarist’s reference library, this permutation-based workbook will enable you to:

  • Explore all of the possibilities for four-part harmony on the guitar
  • Develop a personal harmonic language through the discovery of unique chord voicings and harmonies
  • Improve analytical skills
  • Expand your harmonic palette exponentially
  • Reinforce your current knowledge base by the comprehensive review of four-note chords and arpeggios

Price: $29.99

The Three-Note Chord Compendium is the first mathematically-complete book on three-part guitar harmony ever published. 

Over 150 pages in length, it contains 1,820 unique chord forms for analysis and exploration: every possible combination of three notes on the instrument.

Also included: suggestions for fingerings, practice approach, and harmonic analysis.

An all-encompassing encyclopedic text, and an essential part of every guitarist’s reference library, this permutation-based workbook will enable you to:

New Publication

I’m very excited to announce the publication of my new book on drop chord voicings!

THE DROP VOICING BOOK FOR GUITAR: A Complete Guide to Drop 2, Drop 3, Drop 2&3 and Drop 2&4 Chord Voicings & Inversions

“A superb piece of work, which deserves ample success and lasting impact.” – Ricardo Iznaola 

THE DROP VOICING BOOK FOR GUITAR is a comprehensive text covering the logic behind “drop” voicings and their application to harmonic progressions and voice-leading. This ground-breaking resource investigates/includes:

  • How “drop” voicings are formed, and their application to the guitar
  • Four types of drop voicings on nine string sets
  • The art of spacing or voicing chords
  • Six “core” 6th & 7th chord qualities 
  • How to derive voicings from elemental forms
  • How to move beyond mere memorization and recitation of shapes and voice-lead harmonic textures spontaneously
  • Nine comprehensive studies on the Autumn Leaves chord progression 
  • Reductive techniques to tailor density & register to ensemble/context
  • Using chordal knowledge to improvise harmonically-specific melodies
  • Harmonizing melodies: “chord-melody” playing
  • Extended tertian harmony
  • Substitution & superimposition theory and techniques
  • Alteration techniques to create an enormous palette of additional chord qualities
  • Free audio downloads
  • TAB, standard notation, diagrams, and comprehensive charts for practice and reference

Complete Tetrachord Combinations: Major, Melodic Minor, Harmonic Minor, & Harmonic Major Scale Harmony

This post explores all of the possible tetrachords (four-note combinations) in Major, Melodic Minor, Harmonic Minor, & Harmonic Major Harmony.

(Download the accompanying PDF at the bottom of the post.)

These exhaustive lists may appear too information-packed to be useful. (There are 840 combinations per scale.)

I suggest dipping into them occasionally to more deeply explore the vertical (chords) and horizontal (melody) aspects of their all-important parent scales.

You’ll find every standard approach to chord voicing contained herein, as well as many uncommon sonorities.

Some structures may be impossible to play as chords unless one or more of the tones are raised an octave.

Experiment with the lists, and you’ll discover many new things about these commonly-used harmonic palettes (scales).

Below are a few examples of how the lists can be used to create chords and arpeggios (taking some liberties with octave placement and contour):

Bebop Scales & Harmonization

This post explores voice-leading major & minor 6th & 7th chords, dominant♭5, dominant♭9 & fully-diminished 7th chords, and more, through Bebop Major, Bebop Minor, Bebop Dominant, & Bebop Dominant♭5 scales, along with one & two octave scale fingerings, chord alterations & substitutions.

Triads with Doublings and Suspended 4ths (Harmonized Scale: “D” Harmonic Minor)

The following examples show various four-note triadic constructions with doublings and suspensions moved through a “D” Harmonic Minor scale.

The first chord is a commonly played triad with a duplicated root. The intervals, stacked vertically, are as follows: 5th, 4th, & 3rd. The intervallic construction is maintained and moved through the harmonized scale:

Next, the 3d is suspended (replaced with a diatonic fourth) and the resulting 5th, 4th & 4th construction is moved through the scale:

The second voicing type is a triad with a duplicated 3rd. The intervals, stacked vertically, are as follows: 3rd, 4th, & 3rd. The intervallic structure is maintained and moved through the harmonized scale:

Next, the upper 3d is suspended (replaced with a diatonic fourth) and the resulting 3rd, 4th & 4th construction is moved through the scale:

The third construction is a triad with a duplicated 5th. The intervals, stacked vertically, are as follows: 4th, 3rd, & 3rd. The intervallic structure is maintained and moved through the harmonized scale:

Next, the 3d is suspended (replaced with a diatonic fourth) and the resulting 4th, 4th & 2nd construction is moved through the scale:

Try finding additional four-note triads with duplicate notes or “doublings.” Here are two other possible starting chords:

Also, try transferring these voicings onto other string sets. Here is one of the previous chords transposed down an octave and placed on string set 5432:

Finally, experiment with various scales. Harmonic Minor is particularly useful, however, as it contains Major, Minor, Diminished, and Augmented triads.
