Section 26.12 Summary of Doubling Rules for Triads

To generalize, here are the doubling rules for voice leading triads in root position, first inversion, and second inversion:

  • Root Position Chords: DOUBLE THE BASS

  • First-Inversion Chords: DO NOT DOUBLE THE BASS

    • Exception: \(\left.\text{vii}^{\circ}{}^{6}\right.\)and \(\left.\text{ii}^{\circ}{}^{6}\right.\): DOUBLE THE BASS

    • Exception: Consecutive first inversion chords—alternate between DOUBLE THE BASS and DO NOT DOUBLE THE BASS

  • Second-Inversion Chords: DOUBLE THE BASS
