The fundamental of the lowest note (C0) would be about 16Hz which is a pretty fast "beat". I think the perception of beats comes from all the partials making quasi-chaos. I like the sounds of low notes (32' pipes on organs) I just don't think any piano I've heard does them justice. dp Sent from my BlackBerry® -----Original Message----- From: Fred Sturm <fssturm at unm.edu> Sender: caut-bounces at ptg.org Date: Tue, 18 Jan 2011 12:50:31 To: College & University Technicians<caut at ptg.org> Reply-To: caut at ptg.org Subject: Re: [CAUT] Stuart & Son on NPR On Jan 18, 2011, at 10:46 AM, David M.

The "pitch" we hear is composed of the partials, and whatever the brain does to process them. Regards, Fred Sturm fssturm at unm.edu
