I have an 8 measure piece.
| C / / / / | / / / / | G / / / | C / / / | / / / / | / / / / | G / / /
| C |
Am I correct in my assumption that the G in the third measure needs to
be in root inversion but I do not care what the highest note is and
that the C in the fourth measure is the same. The G in the seventh
measure needs to be in root form with the highest note either B or D
and that the C in the last measure needs to be in root inversion with C
as the highest note?
The G in the third measure doesn't necessarily need to be in root
position, no. You have many possibilities. If the C in the first
measure and the fourth measure are both in root position, then either a
root position G chord or a first inversion G chord will work. If either
of the C chords is not in root position, then other things are possible.
The more usual way to discuss something like this is to give the melody
and discuss what might make the best harmony for it, assuming the melody
is decided already.
If you are trying to write a perfect, authentic cadence at the end then,
by definition, the bass will go G to C, and the melody will be either B
to C or D to C. If you're trying to create some other sort of cadence,
then different rules apply.
In short, exactly what's given and what's up to you is not clear from
