Folks, I have a problem. Has to do with the Scottish highland pipes. I've read about them and I am confused as to the key they play in. There is a friend of mine who's going to put some pipe music on my next CD--assuming there IS a next CD. He's a young fellow with whom I've shared fire response calls and some ambulance calls (he's cross-trained EMS/fire and one gutsy sob). He tells me A or Ab--he thinks. The one instrument he plays is the pipes. The writings I've read start with Hz or something like that and say the 'key' ranges from A440-about A476. Right. Like, man, that means nothing to me, and for sure A476 is not flatter than A. Does anyone know?
