Compose an eight-bar melody with harmony, beginning on the tonic (I or i) chord and ending with a dominant chord (V or V7) returning to the tonic chord

Compose an eight-bar melody with harmony, beginning on the tonic (I or i) chord and ending with a dominant chord (V or V7) returning to the tonic chord. All chords that you use should be in the same key.  While some styles of music certainly have more than one chord per bar, limit yourself to one chord per bar. You may repeat chords from bar to bar, so you do not have to change the harmony every bar.  Write your work on the grand staff, using the treble clef for the melody and the bass clef for the chords or bass line.  Include a time signature.  Label the chords with chord names and Roman numerals.   

The triads and seventh chords that you use should all be complete, having the root, third and fifth (and seventh, if applicable) present.  Instead of writing out full chords in the lower part, you may use a bass line that uses a single note at a time.

if you use non-chord tones, circle them (or list them in your reflection comments) and resolve them properly.  Except for anticipations, resolve non-chord tones (NCT) by stepwise motion.
