I was in an acapella choir at college in upstate NY. Your postings touched off a wave of nostalgia We sang a version of O Magnum Mysterium but it wasn’t the Lauridsun...I’ve not been able to find a recording of the one we sang though Ican still recite a lot of the bass line from pitch memory.(My ear was what got me into the choir in the first place) I don’t do much singing anymore but I still have the ear....I can tell at a distance if it my IV pumps are going off vs’s another nurse’s from their pitch...generally our feeding pumps have two pitches... a c and a csharp and I remember a nurse asking one day..”i wonder which pump is going off...I replied “your is. the c sharp is in room 23 and the c natural is in room 27”**...which it was when she checked it. My love of has helped me in my nursing jobs in lots of ways over the years.(**relative to A440hz)
