I am preparing to give a talk on the wider ramifications of music.
One of the things I wish to demonstrate is that things that look different
are merely analogs but at different scales.
eg if something vibrates at 400Hz we hear a sound of A-flat. If it
'vibrates' at 4 Hz we hear a beat.
In the same analogy a 2 vs 3 poly-rhythm (should?) change to a do-so chord.
And so on.
Is there some kind of software where I can make a 4 Hz beat and pull a
slider or a freq text box entry until it sound like a A-flat note?

I suggest you do some experiments before you give a talk. At 4 Hz you
won't be able to hear anything, you won't even be able to reproduce a
4 Hz sound with common speakers.
Is there some kind of software where I can make a 4 Hz
beat and pull a
slider or a freq text box entry until it sound like a A-flat note?
puredata springs to mind, it's easy to use and has everything you need.

You took me quite literally, [I did put the vibrate into quotes :-) ]
Let me spell out the experiment in more detail:
Say I have a rhythm in 4/4 time -- 4 even quarter notes, bar repeating every
second played by say a click. [What kind of click I am not very sure; sharp
with few harmonics would be best I expect]
Now if there were some (realtime) way of sliding the tempo from 1 sec to
millisec I expect the separate clicks would vanish into a hum at some stage.
This (and other such experiments) is what I want to demo.
Ive started looking at chuck.
How does it compare with puredata?

Search the net for granular-synthesis. Your use-case is not the typical
grain-synth application, but the principle is the same.

It's a bit of an apples vs oranges question.
the main difference: Chuck you program in text, pure-data you
graphically connect "objects" (if you know Max/MSP: pure-data is similar).
AFAIK, Chuck does not offer GUI elements - you'll need to implement the
slider via OSC or use a "text slider".

Indeed. Though chuck, supercollider, csound,... could all do the trick.
If you know neither of those. Pure-data is probably the easiest to get
started with.
http://www.timvets.net/video/grains.php will do what you want with Pd.

It would achieve a similar sound but is functionally quite a different

You are right or course. It's not modeling the desired effect correctly;
Yet it's close enough and much more robust and convicing for a Demo.
Actually http://www.sonicvisualiser.org/ may be the tool of choice.
Here's a video where it is used to slow down some Bach so that you can
hear the "beating/pulsing" introduce by equal-temperament tuning:

Hi Rustom!
Idea: a 2 vs. 3 tuplet that becomes a 5th after 30 seconds
In SuperCollider that would be:
{
var x = XLine.kr(2,200,30);
Ringz.ar(Impulse.ar(x * [2,3]), 440, 0.2, 0.3)
}.play
On in one line:
{Ringz.ar(Impulse.ar(XLine.kr(2,200,30) * [2,3]), 440, 0.2, 0.3)}.play

Oho! Thats succinct! But supercollider seems to have been dropped from
debian.

Actually you can get rid of the Filter and use raw impulses,
would be less writing but worse sounding:
{ Impulse.ar( XLine.kr(2,200,30) * [2,3]) }.play
