The classic perfect cadence is ii7b V I
The Tenor part must always carry the dissonance
The leading note should always fall to the third of the tonic.
The gap between the tenor and bass should be small
You should try to move the outer parts in contrary motion
Semiquavers should be used as passing notes
In a Ib chord you should always double the fifth
A good chord progression to use at imperfect cadences is I Ic V
Dissonances must be prepared, sounded and resolved
The leading note can leap to the third when unable to resolve to the fifth
When using a cadential 6/4 (Ic V I) you must treat the fourth above the bass as a dissonance
In a V7 chord, the seventh must always be prepared
The seventh must always fall
It is a good idea to use viib I at the final cadence
Always use a tiecre de picardi to finish a chorale when in a minor key
