The only telephone-based 440 reference I've found is to dial WWV, which is 303-499-7111 (happens to be a local call for me :-). But it isn't a very convenient source of a 440 pitch -- it only plays it during the 1st minute of each hour, and not during the first hour of each UTC day. -andy On Fri, Jun 5, 2009 at 10:43 AM, Richard Brekne <ricb at pianostemmer.no> wrote: > > Anybody have the name/telephone number of the us based international pitch reference ?
