Dissonant Harmonies, Chords of the Seventh and Chords of the Ninth

• Chords with 4 or 5 tones = dissonant chords
  • This is because their fundamental tone forms a 7th or 9th with the upper most tone
• These chords are not independent
  • They are justified by their resolution to triads
    • Therefore all these chords must be let to triads
• Dissonant chord → consonant chord = resolution
