The recipe linked below plays sounds composed of a fundamental and a few
harmonics. It requires Pygame and NumPy.

It is out of date, though. I had to change 'Numeric' to 'numpy' and 'Int16'
to 'int16' to get it to work.  Moreover NumPy doesn't seem to work with
Python 2.6.


You can also use TkSnack (http://www.speech.kth.se/snack/). Check the
example named 'notescale' that comes with the module: it defines a function
that receives a frequency as an input and plays a sound; there is also a
graphical interface.
