History of Jazz: Musical Elements and Theory

Foundational Musical Elements

• Melody
      - Defined as the linear aspect of music (what we sing). (Or horizontal aspect of music)
      - It represents the horizontal dimension of musical construction.

• Harmony
      - Defined as the vertical aspect of music, typically functioning in the background.
      - Chords: Represented as harmonies or "changes."

• Rhythm
      - Defined as a pattern of events organized in time.
      - Beat: A steady, recurring pulse.
      - Measure (Meter or ‘Bar’): Formed by the grouping of pulses.
      - Rhythm encompasses the beat and the specific patterns of sound and silence occurring within each beat. (Not just the beat, but what happens during the beat)
      - Swing: A specialized rhythmic concept introduced by jazz music. Achieving swing in a rhythm section requires significant coordination and work.

Musical Form and Structure

• Form Overview
      - Form is the structure and organization of melodic and/or harmonic materials.
      - Intro: The introduction of a piece.
      - Chorus: One complete cycle through the entire song structure.
      - Ending/Tag/Coda: Subsequent terms for the conclusion of a musical piece.

• 12 Bar Blues Form
      - Typically structured into $3$ groups of $4$ measures.
      - The basic outline utilizes Roman Numerals $I$, $IV$, and $V$. These refer to major triads built on scale degrees $1$, $4$, and $5$ of any major scale.
      - In a standard Blues progression, it is common to add $7ths$ to all $I$, $IV$, and $V$ chords.

• A-A-B-A Song Form
      - Frequently totals $32$ measures in length.
      - Structured as four sections of $8$ measures each ($8+8+8+8$).

Recorded Performance Case Studies

• Horace Silver Quintet: "Song for My Father" ($1968$)
      - Structure: $24$-Measure $A-A-B$ Form.
      - Each section ($A$, $A$, and $B$) is exactly $8$ measures in length.

• Billy Strayhorn / Duke Ellington: "Take the A Train" ($1943$)
      - Performed by Ellington’s Band.
      - Structural Breakdown:
          - $4$ Bar Intro.
          - $32$ Measures total (structured as $8+8+8+8$).
          - Uses a $4$ beat bar.
          - Includes an $8$ Bar Break.

Scales and Musical Keys

• Terminology
      - A scale is synonymous with a Key.

• Diatonic Scale (7-Note Step-wise Scale)
      - Structure ($C$ Major Example):
          - Note/Position $1$: $C$ | Solfege: DO | Name: Tonic
          - Note/Position $2$: $D$ | Solfege: RE | Name: Supertonic
          - Note/Position $3$: $E$ | Solfege: MI | Name: Mediant
          - Note/Position $4$: $F$ | Solfege: FA | Name: Subdominant
          - Note/Position $5$: $G$ | Solfege: SO | Name: Dominant
          - Note/Position $6$: $A$ | Solfege: LA | Name: Submediant
          - Note/Position $7$: $B$ | Solfege: TI | Name: Leading Tone

• Pentatonic Scale (5-Note Scale)
      - Components ($C$ Example): $C-D-E-G-A-C$
      - Step Structure: $W+H, W, H, H, W+H, W$

• C Blues Scale
      - Specific notes included in the scale: C, E\flat, F, F#, G, B\flat, C

Rhythm and Syncopation Techniques

• Syncopation Details
      - Definition: The emphasis of a weak beat, the emphasis of a weak part of a beat, or the complete omission of a strong beat.
      - Methods of producing syncopation include:
          - Rests (as shown in Example $2$).
          - Short Notes (as shown in Example $3$).
          - Ties (as shown in Example $5$).

• Swing Drumming
      - Uses the "four on the floor" basic swing beat for a drum set, focusing on specific accented patterns to create the swing feel.
