Usage

@ديفيد عادل وهبة خليل 2, ArthurPSmith, Germartin1, Cwf97, Alexander Doria: I've tried using this at Someone Like You (Q166904), with new items for all of the progressions. (I tried to pick a simple example but forgot the song has at least five different progressions as well as time signature changes.) I've left out some of the lists of chords because some of the items don't exist yet. I've only gone to the end of the first chorus, but other than the bridge the rest of the song should look almost the same.

Is there anything that could be improved about the structure/statements? In particular, since it would sometimes be appropriate to use a single chord as a value for this property on items about compositions/tracks, should the items for the chord progressions themselves use chord progression (P6116) or has part(s) (P527) to list the chords?

I think the relation to the main key is the more important one, which you're capturing via the subclass relations. But you seem to be doing a nice job of modeling here, I don't have any strong opinions on ways to do it differently. ArthurPSmith (talk) 15:11, 13 November 2018 (UTC)
