📖 Theory Fundamentals

Harmonic Functions

  • •I (Tonic): Stability, home base, point of departure
  • •vi (Submediant): Relative minor, adds melancholy and emotional depth
  • •IV (Subdominant): Movement and tension, pulls away from home
  • •V (Dominant): Maximum yearning, demands resolution back to I
  • •Emotional Arc: Happy → Sad → Searching → Yearning → Resolution

C Major Example

  • •I: C Major (C-E-G)
  • •vi: A Minor (A-C-E)
  • •IV: F Major (F-A-C)
  • •V: G Major (G-B-D)
  • •Progression: C - Am - F - G

🔄 Scale Relationships & Theory

Diatonic Relationships

Scale Degrees in C Major

  • • I (C): 1st degree - Tonic
  • • vi (Am): 6th degree - Relative minor
  • • IV (F): 4th degree - Subdominant
  • • V (G): 5th degree - Dominant
  • • All four chords are diatonic to C major

Shared Notes Between Chords

  • • C (C-E-G) and Am (A-C-E) share C and E
  • • Am (A-C-E) and F (F-A-C) share A and C
  • • F (F-A-C) and G (G-B-D) share no notes
  • • This note sharing creates smooth voice leading

Emotional & Functional Analysis

Why It Works

  • • I and vi are closely related (relative major/minor)
  • • Moving to vi introduces minor quality (sadness)
  • • IV creates forward motion away from home
  • • V creates maximum tension for resolution back to I
  • • The cycle creates a complete emotional journey

Scales for Soloing

  • • C major pentatonic works over entire progression
  • • A minor pentatonic for bluesy soloing
  • • Target chord tones on each change
  • • Use the full C major scale for melodic playing
