Here are some terms and concepts that we will refer to.

PAC – Perfect Authentic Cadence. Dominant moving to Tonic. Stereotypical end of a tonal piece. So-do in the bass, do in the soprano

IAC – Imperfect Authentic Cadence. Dominant moving to Tonic. Destabilized version of PAC, either because of inversion, pitch in the soprano, or Dominant substitution.

HC – Half Cadence. Cadence for phrases ending on Dominant. No requirement for the previous chord. (A Phrygian HC involves le-so in the bass.)

Plagal Cadence – Predominant moving to Tonic. Associated with “Amen” from hymns. Usually happens after an authentic cadence (PAC or IAC).
