This chart has a listing for a chord V/1 and I'm having trouble interpreting this chord, specifically the "/1" part. I think the "/1" part might have one of the following meanings...
- "the base note of the chord (in this case, the fifth note in the scale) as the lowest note"
- "the first note of the scale as the lowest note"
- "the first inversion of the chord"
What is the proper way to interpret V/1?
