Either or both could be in major or minor. If minor – ALWAYS harmonic!!!
There will be a half, deceptive, or authentic cadence at the end.
The SOPRANO will likely end on the root or 3rd of the last chord.
FR 3 = all diatonic.
FR 4 = one chromatic chord – probably V/V, V/IV, V/vi, V/ii, or viio7/V (think about what scale degrees are chromatic for these!!)
IF/THENs:
If LT in bass, then V6 (or V 6/5)
If mediant in bass, then I6
If bass repeats a note, they are DIFFERENT roman numerals. Most common are the ii6 – IV, and the I6/4 – V
You will only notate the Soprano, the Bass, and the Roman Numerals.
Before you move on, you will USE THE FOURS.
Opening Harmonic Patterns:
I V6 I

Closing Harmonic Patterns:
I6/4 V I (could be deceptive vi)
ii V I (could be deceptive vi)
IV V
IV V I (could be deceptive vi)
ii V
