As part of the hyperion clean-up, I was looking at this one: https://musicbrainz.org/release/a5cbf9c4-24ab-3326-a894-07526fa36228 (Angela Hewitt - Goldberg variations - 1st version). The metadata in MusicBrainz is rather less informative than that provided by hyperion here: https://www.hyperion-records.co.uk/dc.asp?dc=D_CDA67305. Neither MB nor the CD booklet has the additional information about each variation which is given in hyperion’s tags. A little research shows that those tags follow the descriptions in the original score (e.g. http://hz.imslp.info/files/imglnks/usimg/0/07/IMSLP394103-PMLP02982-N55005962_(BWV_988).pdf) which is somewhat ironic as Hewitt is playing on a piano not a harpsichord. Other recordings (e.g. this one: https://musicbrainz.org/release/b304abb5-c039-494f-bc50-37490aca74c5) use the titles as in the score which are (presumably - I don’t have it) on the sleevenotes.
It seems to me that the original score titles should be in the work names, rather than just plain “Variation 1” etc. The track titles should be what is on the cover etc. Even if a variation is played on the piano, it is nice to know that it was written for “2 Clav.” as you can appreciate the hand-crossing tricks the musician is having to perform.
That said, I am loathe to change the titles of such an important work without some general agreement. Views?
