Calculating tension in music

Had the idea to sum the tension values of each note, and divide that against the cumulative possible total. Showed ~30% tension in common chord progressions. That 30% can be used to define how much tension should be in the Motif.

However, I need to return a FPerBarSchedule, and I started thinking about if there was a better way to map Note + Octave than doing a FilterByPredicate().

So I created an enum of C0 → C6 and all inclusive notes. But then I got stuck thinking about how I would convert a GetMyNote(Octave, Note) into enum value EFlat3.

I got frustrated and ended early.
