In the database, I’ve came into conflict between users over mixing up modes, so I like to request a two changes:
- allow us to tell if the song is in a relative mode.
- allow us to tell if the song modulated into a parallel mode.
Like if a chord progression goes like v-i-VII-III, you can allow the users too tell us the VII-III is a V-I in the relative major. In addition to that, you can also tell the user if a section of a chord progression has modulated to a parallel mode.
