Comprehensive Guide to Music Theory Tensions, Voicings, Audio Production, and Social Debates

Fundamentals of Diatonic Tensions

• Definition and Origin:

  • Diatonic tensions are extended harmonic pitches derived directly from the notes of a major scale.

  • They correspond to the second, fourth, and sixth scale degrees of the major scale, raised by an octave:

  • Second scale degree ($2\text{nd}$) = Nine ($9$), located a major second (whole step) above the root.

  • Fourth scale degree ($4\text{th}$) = Eleven ($11$), located a perfect fourth above the root.

  • Sixth scale degree ($6\text{th}$) = Thirteen ($13$), located a major sixth above the root.

• Notation Standards:

  • Berklee Method: Tensions are explicitly enclosed in parentheses following the base chord quality (e.g., $F7(9, 13)$ or $F\text{maj7}(9)$).

  • Lead Sheet Notation: Frequently simplified to direct shorthand such as $F\text{maj9}$ or $F\text{maj13}$. Standard lead sheets deliberately omit $F\text{maj11}$ due to severe inherent harmonic dissonance.

• Major Sixth ($6\text{th}$) Chords vs. Seventh Chords:

  • Major sixth chords contain no seventh degree. The basic chord formula is $1, 3, 5, 6$.

  • Major 6 Chord Structure: $1, 3, 5, 6$ (contains a major third and a major sixth interval).

  • Minor 6 Chord Structure: $1, \flat 3, 5, 6$ (contains a minor third and a major sixth interval; both major 6 and minor 6 chords utilize a major sixth interval).

  • Harmonic Function: Sixth chords serve as a bright, resolved, and colorful alternative to tonic major seventh chords. Major seventh chords possess an inherent dissonance that can feel unresolved at the final cadence of a composition, whereas a major sixth chord offers complete tonic stability and harmonic relaxation.

  • Alternating between a major seventh and a major sixth chord creates subtle harmonic motion without altering the underlying tonic function.

Major, Minor, and Dominant Chord Tension Rules

• Avoidance of the $11\text{th}$ Tension on Major Chords:

  • The $11\text{th}$ extension is strictly avoided on major seventh chords because it creates an extreme, biting dissonance against the major third ($3\text{rd}$) of the chord.

  • The interval between the major third and the perfect fourth ($11\text{th}$) is a minor second (half step). Minor second interval collisions produce severe harmonic clash.

  • Major chords primarily utilize the $9\text{th}$ and $13\text{th}$ tensions, which provide a bright, open sound.

• Suspended Chords ($\text{sus}$):

  • Suspended chords utilize the $4\text{th}$ / $11\text{th}$ interval in place of the third, eliminating the minor second collision.

  • Standard chord symbol notation: $F7\text{sus}$ or $F7\text{sus}(9, 13)$.

  • Classic repertoire application: Herbie Hancock's composition "Maiden Voyage" heavily utilizes $\text{sus}9(13)$ chords.

• Minor Chord Tension Rules:

  • Unlike major chords, minor seventh chords readily accept the $11\text{th}$ tension.

  • On a minor chord, the interval between the minor third ($ lat 3$) and the perfect fourth ($11\text{th}$) is a whole step (major second), eliminating harsh minor-second dissonance.

• General Whole-Step Test for Available Tensions:

  • To determine if a tension is harmonically available on a chord, verify if the tension sits a whole step (major second) above the chord tone directly beneath it:

  • Nine ($9$): A whole step above the root ($1$). Available on major, minor, and dominant chords.

  • Eleven ($11$): A whole step above the minor third ($ lat 3$). Available on minor chords and half-diminished chords.

  • Thirteen ($13$): A whole step above the fifth ($5$). Available on major, minor, and dominant chords.

• Half-Diminished / Minor 7 Flat 5 ($m7\flat 5$) Chords:

  • The primary available extension is the $11\text{th}$.

  • The $9\text{th}$ is generally avoided, and the $13\text{th}$ is omitted due to intervallic clash.

Chromatic Tensions and Dominant Chord Function

• Role and Nature of Dominant Chords:

  • Dominant chords function to create instability, tension, and forward harmonic momentum.

  • Adding chromatic alterations (non-diatonic pitch modifications) intensifies the harmonic drive toward resolution.

• Catalog of Chromatic Tensions:

  • Flat Nine ($ lat 9$): Positioned a half step above the root (minor second above the root).

  • Sharp Nine ($ ext{#}9$): An augmented second / minor third sound above the root.

  • Sharp Eleven ($ ext{#}11$): An augmented fourth above the root.

  • Flat Thirteen ($ lat 13$): A minor sixth above the root.

  • Flat Seven ($ lat 7$): A foundational chord tone, not a tension extension.

  • Nomenclature Constraints: There is no such term as a sharp 13 ($ ext{#}13$) or flat 11 ($ lat 11$). A flat 11 is enharmonically equivalent to a major third, and a sharp 13 creates unusable dissonance on major quality chords.

  • Summary of Tension Alterations: Three forms of nines ($9, \flat 9, \text{\#}9$), two forms of elevens ($11, \text{\#}11$), and two forms of thirteens ($13, \flat 13$).

• The Sharp Nine ($ ext{#}9$) Rule:

  • A minor third played over a dominant chord structure containing a major third functions as a sharp nine ($ ext{#}9$).

  • In the key of $G$, over an $E7$ chord, playing a $G\text{ natural}$ provides the minor third sound that functions as the $ ext{#}9$, avoiding double-sharp notation ($G\text{\#}\text{\#}$).

• Dominant Resolution Patterns:

  • Dominant chords resolve down a perfect fifth ($P5$) or down a half step (substitute dominant / tritone resolution).

  • Example resolution progressions:

  • $G7 \rightarrow C$

  • $G7\flat 9 \rightarrow C6$

  • $G7\text{\#}9(\flat 13) \rightarrow C\text{maj7}$

  • $D7\flat 9 \rightarrow G\text{m7}$ (adding $ lat 9$ increases the harmonic payoff of the resolution compared to an unaltered $D7$).

Diatonic Tension Availability by Scale Degree

• Diatonic Chart for Major Scale Degrees:

  • $I\text{maj7}$ (Tonic): Available tensions are $9$ and $13$.

  • $ii\text{m7}$ (Supertonic): Available tensions are $9$ and $11$.

  • Special Constraint: The $13\text{th}$ tension is strictly avoided on $ii\text{m7}$ chords within a $ii - V - I$ progression because including the $13\text{th}$ makes the supertonic chord sound like the dominant $V7$ chord, undermining harmonic movement. Flat 13 ($ lat 13$) is likewise avoided on $ii\text{m7}$.

  • $iii\text{m7}$ (Mediant): Available tension is $11$.

  • $IV\text{maj7}$ (Subdominant): Available tensions are $9$, $\text{\#}11$, and $13$.

  • $V7$ (Dominant): Available diatonic tensions are $9$ and $13$ (along with chromatic altered tensions $ lat 9, ext{#}9, ext{#}11, lat 13$).

  • $vi\text{m7}$ (Submediant): Available tensions are $9$ and $11$.

  • $vii^\circ\text{m7}\flat 5$ (Leading Tone / Half-Diminished): Available tensions are $11$ and $\flat 13$.

• Fundamental Rule of Exclusion:

  • Tensions that reside a half step above a chord tone directly below them must be avoided to prevent harsh dissonance.

Voice Leading, Voicing Types, and Chord Construction

• Physical Performance and Distribution Rules:

  • Tensions and extended chords generally require two-hand distribution on keyboard instruments.

  • Attempting to play five-note tension chords in close position with one hand (using fingers 1 through 5) creates extreme physical strain and hand tension.

  • Standard physical arrangement: The root is played in the left hand (bass), while the remaining chord tones and tensions are voiced in the right hand.

  • The fifth ($5\text{th}$) degree of a chord is non-essential and is frequently omitted to thin out dense chord structures without altering chord identity.

• Four-Part Closed Position Rules:

  • Four-part closed voicings keep all four voices packed within a single octave range.

  • When adding tensions to a four-part closed structure:

  • The nine ($9$) replaces the root ($1$) in the upper structure (the root is maintained solely in the bass).

  • The thirteen ($13$) replaces the fifth ($5$).

  • The nine ($9$) and thirteen ($13$) operate as a standard paired team.

  • Example $F\text{maj13}$ construction: $7, 9, 3, 13$ ($E, G, A, D$).

• Classified Voicing Categories:

  • Four-Part Closed Position: All four notes are kept as close together as physically possible within an octave band.

  • Open / Spread Voicings: Notes are distributed across wider intervals spanning multiple octaves.

  • Drop 2 Voicings: Constructed by taking a closed-position four-part chord and dropping the second note from the top down exactly one octave into the lower register.

  • This placement positions essential structural tones (such as the 3rd and 7th) near the bottom of the voicing ($1 - 3 - 7$ or $1 - 7 - 3$).

  • Guide Tone Voicings (Three-Part Voicings):

  • Uses the 3rd and 7th degrees of the chord (the "guide tones"), which supply the core harmonic identity.

  • Common configurations: $1 - 7 - 3$ or $1 - 3 - 7$, with the highest voice assigned to the $5\text{th}$ or $9\text{th}$.

Harmonic Analysis and Application Steps

• Analytical Rules for Roman Numeral Identification:

  • In a key signature with two sharps ($F\text{\#}, C\text{\#}$), the key is $D$ major.

  • Degree $I$ is $D\text{maj7}$ / $D\text{maj9}$.

  • Degree $IV$ is $G\text{maj7}$.

  • If a $G$ chord contains an $A$ ($9$) and a $C\text{\#}$ ($ ext{#}11$), the chord symbol is $G\text{maj7}(\text{\#}11)$ or $G\text{maj9}(\text{\#}11)$, which aligns with the available tensions for the subdominant degree.

• Interval Transformation Principles:

  • Second scale degrees ($2$) transform into Nines ($9$).

  • Fourth scale degrees ($4$) transform into Elevens ($11$).

  • Sixth scale degrees ($6$) transform into Thirteens ($13$).

• Melodic Use of Tensions:

  • Tensions are not restricted to chordal accompaniment; melodies frequently jump between tension degrees (e.g., moving between $9, \text{\#}9, 13,$ and $\flat 13$) to inject vivid color into a musical line.

Vocal Production and Audio Processing Chain

• Microphone Selection: Chandler RED microphone utilized for tracking vocal performances in home studio environments.

• Signal Processing Chain Order:

  1. Equalization (EQ): Simple high-pass EQ filter band cutting off low-end frequencies.

  2. De-Esser: Applied to suppress vocal sibilance.

  3. Compressor: Controls dynamic range.

  4. Pitch Correction: UAD Auto-Tune plugin for precise intonation control.

  5. Tonal Enhancement: CLA Vocals processing plugin.

  6. Reverb & Delay Effects: Valhalla Vintage Reverb paired with EchoBoy set to a slap delay pattern.

Debates on Culture, Demographics, and Traditional Family Structures

• Demographic Rates and Economic Growth Arguments:

  • Proponents of traditional family models argue that falling fertility rates below replacement levels threaten long-term economic stability.

  • Assertions emphasize that high birth rates (e.g., targeting ten children per family) are necessary to maintain workforce expansion.

  • Cumulative statistical claims cite a loss of 45 million potential workers from historical demographic deficits.

• Cultural and Societal Perspectives:

  • Critique of the Sexual Revolution asserts that it operated as an organized effort to dismantle paternal authority ($patriarchy$) and expand state control over domestic life.

  • Counterarguments focus on modern economic constraints: inflation and housing costs make single-income households difficult to sustain, forcing reliance on dual-income arrangements.

  • Discussions highlight the economic value of domestic labor performed by stay-at-home parents vs. external workforce participation, alongside social research regarding child outcomes in stable, two-parent households with involved fathers.

Animal Welfare Advocacy and Legal Reform

• International Animal Rights Campaigns:

  • Advocacy efforts target severe animal cruelty incidents, such as the publicized torture and burning of a dog named Wang Wang in China.

  • Campaign goals center on persuading national governments (e.g., China) to enact formal, enforceable national animal cruelty protection legislation.

• Direct Action Tactics:

  • Delivering formal petitions and appeal letters directly to consular offices and embassies.

  • Leveraging diplomatic summits (e.g., bilateral meetings between national leaders) to elevate animal protection issues onto executive agendas.

  • Organizing public street protests and distributing petitions through advocacy platforms such as Lady Freethinker and Change.org.
