As requested during our in-class review at the start of the semester, we discussed four types of cadences:
Authentic (V-I) -- The strongest cadence in tonal music. Also known as the full, final and full close cadence.
Plagal (IV-I) -- The "Amen" cadence.
Deceptive (most common V-vi)
Half (I-V)

The Authentic and Plagal cadences are called perfect when in root position with the tonic in the upper voice; imperfect when the tonic is not in the upper voice. (The perfect Plagal cadence is not shown below.)

We will discuss cadences later on in Chapter 10. For now, some examples are provided below. If you have the Beatnik plug-in installed, click the bass note of the first chord of each progression to hear the cadence.
