The Acoustics Laboratory, part of the School of Physics at the
University of New South Wales, Sydney, Australia has launched a
new web site, an Introduction to the acoustics of brass instruments.
Here is the URL:
The site currently offers seventeen sections ranging from a basic
overview, through closed and open pipes, to mutes, valves and slides.
There is discussion of issues such as intonation, pipe length, and
out-of-tune harmonics; the site is illustrated with many diagrams
and spectra. There are also many musical and sound examples as .wav
and .mp3 files.
The site, developed by Joe Wolfe, is still being added to, and
further material will be published on different bore shapes, frequency
response and acoustic impedance, and the didjeridu.
