I'm wondering if there might not be something structurally wrong with the piano. A m3 flat on an Acro is (I guess) possible without structural problems. I personally haven't come across anything that flat except old dead uprights. Not sure exactly what the beat rates are supposed to be for a flat piano. If I must tune flat, I always tune like I normally would because 1) that's my procedure, and 2) it doesn't really matter so much to me what the beat rates are on a piano that will be kept flat. I'm certainly not losing any sleep over it. :-) I normally tune to A440 unless I think the piano just won't do well there. Maybe someone else has the answer to this question. -- JF On Thu, Jan 1, 2009 at 7:46 PM, Greg Livingston <pianotuner440 at hotmail.com>wrote: > Dear Friends, > > We have been told that the beat rate for A3-C#4 is about 9 bps; F3-A3 is > about 7 bps; do these beat rates only apply when A4 is close to 440? > > If A3 on a neglected piano is closer to F#, are those beat rates the same? > > I recently tuned the most out-of-tune Acrosonic I've ever seen in 22 years > of tuning.
