While adding a recording of Beethoven’s 4th piano concerto op. 58, I notice this work (and part 1 & 3) has a few relationships to cadenzas in the form: “is the basis for”
→ Like in https://musicbrainz.org/work/60da45e9-2479-3b95-91ba-45d27ee14897 is the basis for Work “Cadenza to Beethoven’s Piano Concerto no. 4: I. Allegro moderato” - MusicBrainz
To me this sounds like a strange relationship, as a cadenza is not (necessarily) “based on” the work it is written/improvised for. It’s a freeform addition/intermezzo within the piece. It might be based on a proposed cadenza of the composer, but not necessarily.
I wonder, wouldn’t it be better to introduce a specific relationships, especially for a cadenzas?
So we will have instead, for example:
https://musicbrainz.org/work/60da45e9-2479-3b95-91ba-45d27ee14897 is a cadenza for Work “Concerto for Piano and Orchestra no. 4 in G major, op. 58: III. Rondo. Vivace” - MusicBrainz
That way, cadenzas will also show as a separate list from works which are actually based on a certain composition.
(?I have no idea why sometimes an url appears, and sometimes the name of the work in my post here…?)
