| Not only does the subdominant come too late in the movement for this key to function as anything other than a component, on a large scale, of a plagal cadence. |
| Imagine if Perotin had copyrighted the plagal cadence, or Jelly Roll Morton the flattened fifth? |
| Thus the melody itself was said to be either authentic or plagal, according to whether it had one or two tonics. |
| A plagal cadence is one in which the tonic chord is preceded by the sub-dominant chord. |
| The structure of authentic and plagal Modes was explained, and examples given of melodies formed on them. |
| These enharmonic passages recur to satiety, and the abuse of the plagal cadence deprives it of its religious solemnity. |
