Dominant Seventh Chord

The most important seventh chord, built on the fifth scale degree with a major triad plus minor seventh, creating maximum harmonic tension through its tritone interval and driving powerfully toward tonic resolution.

I. Conceptual Positioning

🎯Problem Solved

How to create the strongest possible harmonic drive to tonicβ€”the dominant seventh's tritone and dual tendency tones (leading tone and seventh) make it the most powerful chord in tonal music.

πŸ”¨Skills Built

  • β€’Construct dominant seventh chords in all keys
  • β€’Resolve V7 β†’ I with proper voice leading
  • β€’Understand tritone resolution (expanding/contracting)
  • β€’Apply dominant seventh in blues, jazz, classical
  • β€’Use secondary dominants (V7/V, V7/IV, etc.)

What This Unlocks

  • Enables strongest cadences (V7 β†’ I)

  • Foundation for blues progressions (I7-IV7-V7)

  • Basis for secondary dominants

  • Creates characteristic blues/jazz sound
