Use this & a famous video game music to review V7 chord & -7 interval in all 12 keys

I used to use the famous “So So Ti Re Fa “ bass intro from 1964 to talk about the V7 chord and what is the minor 7th interval.
30+ years later… a brilliant young soul finally responded with « how about using this video game music”.
Now everyone can relate!
Voilà, this video! :)

0:01 G7 (C major & c minor)
