A lot of women musicians weren't being hired when they were actually seen, but when they were only heard and not seen, suddenly they sounded better and a lot more skilled to the people vetting them. Funny that. Also, women are kept out of music professionally in other ways, too. For example, piano size: women have smaller hands and can incur permanent nerve damage from playing instrument designed for and by men (completely forgetting that the female sex exists, as usual). There have already been extremely talented pianists' careers ruined over this. There are now 7/8 size piano keys for women, but the pianos that have those cost about $10,000 (USD, I think), and so not easy to get access to. There is only one digital keyboard with smaller keys and it only has 61, not 88, keys. So not enough to practice classical pieces on for auditions. There is another upright piano with 7/8 keys for 5 grand, that's more affordable but still expensive Some universities have thankfully purchased these 7/8 key size grand pianos so some students can access them, but there's only one manufacturer so far meeting this very widespread demand. Just another example of women being ignored and erased for so long, this is an issue that should ahem been addressed ages ago.

So, yeah, blind auditions and anything else that makes it physically possible for women to become pro musicians where they previously would be prevented by the extent male supremacy is a good thing. Getting rid of blind auditions is dumb as shit, they might as well stop making those smaller pianos, too.
