Neo Soul Chord Progressions: Advanced Harmony Techniques

This section covers two interconnected concepts for creating tension in blues playing. First, altered dominant chords (A7 with sharp 5, flat 9, etc.) contain notes outside the key that create extra tension when resolving to the four chord. Second, tritone substitution allows substituting one dominant chord for another a tritone away (A7 and Eb7 share the same third and seventh). This explains why blues players often slide a half step into the four chord—it creates a gravitational pull that resolves naturally. These concepts can be superimposed over simple blues backing tracks to create sophisticated tension.

Tritone substitution replaces a dominant seven chord with another dominant seven chord a tritone away. This works because both chords share the same third and seventh notes (inverted), preserving the chord's fundamental character while introducing chromatic tension. The technique applies to any dominant chord resolving to a tonic. In the 2-5-1 progression, substituting G7 with D♭7 creates a chromatic walk-down effect. Secondary dominance expands possibilities by adding V chords before each chord, generating multiple substitution opportunities. In circle-of-fifths progressions like 3-6-2-5-1, converting chords to secondary dominants enables sophisticated chromatic voice leading through strategic tritone substitutions.

Tritone substitution replaces a dominant chord with another dominant chord a tritone away. For Bb7 to Eb, substitute E7 to A. This changes note functions: the 13th becomes sharp 9, flat 9 becomes sharp 5, and 3 becomes 7, creating an altered dominant sound. The same technique applies to minor keys (G7 to C minor becomes C#7 with flat 9 and flat 5). This creates rich, colorful sounds that can resolve to minor or major chords, expanding harmonic possibilities.

Tritone substitution is a jazz harmony technique that creates surprising sounds by substituting dominant chords with chords a tritone away. It only works for dominant chords that resolve. G7 and Db7 share the same third (Bb) and seventh (F), making them substitutable. In a 2-5-1 progression, G7 can be replaced with Db7, creating more tension. Multiple dominants in progressions can each receive substitution. The Db7 substitute in C major requires Db Lydian dominant, equivalent to Ab melodic minor and G altered. Four useful arpeggios: third of chord, third of substitute, fifth-based arpeggio, and seventh-based arpeggio. Common altered voicings derive from Db7: Db7 with 9th equals G7 with flat 9 on 5/13. Starting with tritone substitution material is more effective than using the altered scale directly. Practice by applying tritone substitution in song contexts like 'Stella by Starlight' bridges. Tritone substitution and altered dominance are both part of melodic minor harmony, making it a foundational tool for jazz improvisation.

This section explores two advanced improvisation concepts. First, chromatic passing tones are extra notes inserted into scale runs to create harmonic flavor and ensure proper resolution to target chord tones on downbeats. Second, altered dominant chords (like A7 altered) contain tensions including flat nine, sharp nine, and flat seven. The instructor explains that finding the starting point for such licks is challenging as they may not begin on downbeats. The key element that sells any lick is the resolution - how phrases resolve to chord tones on downbeats, such as chromatically resolving to the third of the target chord.

This segment demonstrates modal interchange—the borrowing of chords from parallel modes—and shows how this technique creates harmonic color and tension. The video illustrates how borrowed chords expand harmonic vocabulary beyond diatonic possibilities.

Modal interchange involves borrowing chords from parallel modes to create unexpected harmonic colors. The instructor demonstrates using a Bb major chord (borrowed from the parallel minor key) to add dramatic, epic quality to the piece, showing how this technique expands harmonic vocabulary beyond the diatonic scale.

Modal interchange, also known as borrowed chords or modal mixture, is a harmonic technique where non-diatonic chords are borrowed from a parallel key (a key that shares the same tonic note but has different notes, such as C major and C minor) to add harmonic variety to a chord progression; this technique involves temporarily moving away from the key center before resolving back to the original key, with common examples including borrowing the ii chord (D half-diminished) or iv chord (F minor) from the parallel minor scale in a major key context.

This segment demonstrates modal interchange, the practice of borrowing chords from parallel modes to expand harmonic vocabulary. The video shows how musicians create unexpected harmonic colors by temporarily shifting between major and minor tonalities, illustrating advanced techniques for enhancing musical expressiveness.

The video demonstrates modal interchange, where chords from parallel modes are borrowed to create harmonic interest. This technique involves temporarily shifting to a related mode to introduce new harmonic colors. The performer shows understanding of how borrowing chords from parallel modes can enrich harmonic vocabulary while maintaining tonal coherence.

Developing comping skills requires progressive rhythmic development: starting with quarter notes, advancing to half notes, whole notes, and off-beats, then incorporating eighth notes including doubled eighth notes. Doubled eighth notes require special articulation—hitting the first note stronger while making the second lighter and shorter. The instructor emphasizes holding off on the second eighth note almost until the next beat occurs to achieve authentic swing feel. Listening to favorite blues recordings and singing along with comping rhythms helps internalize the groove. This systematic approach builds rhythmic flexibility and musical intuition essential for effective jazz accompaniment.

Syncopation is the rhythmic technique of juxtaposing upbeats and downbeats to create swing. To practice, play simple eighth note lines over a blues progression and selectively accent the upbeat notes (the 'and' of each beat) rather than the downbeats. This creates a swinging feel regardless of what notes are played. Practice by playing continuous eighth note lines while selectively accenting different upbeat positions. This technique is fundamental to jazz rhythm and should be practiced selectively rather than constantly to avoid sounding corny.

This segment explores two interconnected concepts: (1) Maintaining consistent groove in neo-soul by playing the same amount of rhythmic displacement every time, which is essential for entrainment—the body's physical ability to feel rhythm; (2) The importance of developing musical ideas beyond simple repeated riffs. The segment emphasizes that intermediate improvisers should be able to sing what they play, as this test reveals whether they truly understand their musical choices rather than merely letting fingers fly. For progressive music, taking simple ideas and mutating them creatively (as bands like Styx and Lockjaw do) creates more interesting musical statements than simply repeating patterns.

Neo Soul music uses distinctive chord voicings including Bb minor 11, Ab add 2 over C, and Db major chords. These chords create a warm, soulful sound characteristic of the genre. The instructor emphasizes that swing 16th notes are the fundamental rhythmic foundation for playing funky jazz music. These rhythms must be internalized and accessible at all times during performance. The instructor recommends setting a metronome and practicing by saying the rhythms aloud to develop this essential rhythmic foundation.

Comping is the art of accompanying in jazz drumming, primarily using snare and bass drums. The foundational exercise involves playing swing time with two and four on the hi-hat, then placing notes on the snare drum. Starting with single notes on downbeats (1, 2, 3, 4), the pattern shifts across each beat. The same concept applies to upbeats (the 'ands' between main beats). Once the eighth note grid is established, the next step is playing two notes per measure at random positions, developing rhythmic vocabulary and flexibility. This progression from simple to complex patterns builds the essential vocabulary needed for authentic jazz comping.

This video presents a complete chord-scale dictionary for jazz improvisation, establishing that successful improvisation depends on matching scales to chord qualities. The fundamental principle is identifying which notes compose a chord and selecting scales that contain those same notes. Major chords use major/Lydian scales; minor chords use Dorian/melodic minor scales; dominant chords use Mixolydian/Lydian dominant/altered scales; half-diminished chords use Locrian/Locrian sharp two scales. Each chord type has specific scale relationships based on its extensions and tensions, providing a systematic approach to selecting appropriate scales for improvisation.

Russell treats chords and scales as interchangeable concepts—chords are incomplete voicings of scales, and scales are melodic realizations of chords. To find a chord's parent scale, walk up the ladder of perfect fifths from the chord's root. Major chords use Lydian from their own root; dominant 7ths use Lydian from the note a whole step below (since dominants are born on the 2nd); minor 7ths use Lydian from their 3rd; half-diminished 7ths use Lydian from their #4. Extended chords requiring the Consonant Nucleus include augmented dominant 7ths (on b6 of Lydian Augmented), diminished 7ths (on Lydian Diminished), and augmented major 7ths (on Lydian Augmented). The parent scale is the most natural choice maximizing ingoing tendency, but any scale on the same root works, offering flexibility beyond rigid chord-scale pairings.

Every chord has multiple corresponding scales that can be used for improvisation, and the choice of scale determines the musical flavor or mood—minor chords can use Aeolian (darker/melancholy), Dorian (more uplifting), Phrygian, Melodic Minor, or Harmonic Minor scales, while dominant seventh chords can use Mixolydian, Altered Dominant, or Diminished scales; understanding these relationships allows guitarists to create specific emotional colors in their playing by selecting appropriate scales based on the desired sound.

Once musicians understand which notes belong to each chord, they can build more complex melodic lines by connecting chord notes from different chords. This approach allows musicians to play more notes while maintaining harmonic coherence. By starting with one chord note, then moving to another chord note, and continuing to connect notes from different chords, musicians can create attractive, flowing solos that are always related to the underlying harmony.

Guitar improvisation improves when players understand the connection between chords and scales, specifically by recognizing that major chord tones are often located within the minor pentatonic scale at the fingertips, allowing for tasteful integration of major and minor pentatonic notes without complex fretboard movements.
