I had my small harp tuned for some years in 432 Hz and I liked it a lot. But when I started to play with other people I had to tune it at 440 Hz – especially because there were instruments like the accordion who could not tune down.
But I read many articles about the 432 Hz tuning. I think I remember some comments that as professional singer you do ruin your voice if you sing in 440 Hz the whole time. Many professional musicians try to bring back the official frequence to 432 Hz – but so far without success.
