no fan of overhead fans while tuning

[Andrew and Rebeca Anderson]

Dave,
Here in south Texas that is more of a problem.  I'm always turning 
off ceiling fans.  But the problem doesn't stop here.  The noise 
coming out of the air-conditioner ducts is a harmonic as well.  It is 
too hot here to turn that off so I grin and bear it.  When the whole 
note blooms around the beat, you know you're there.
