Wind Instruments

Supplement for chapter 16

This page contains 4 YouTube videos that were invisible on the life-site.

University of New South Wales group does it again, repeatedly. The best stuff on the web (or in the literature), most of it their own original research:

Here is a part of the UNSW website rich with examples and discussion of Saxophone - vocal tract interactions.

Also from Joe Wolfe and the University of New South Wales, a very helpful discussion and "Physclips" about an instructive hybrid "Flarinet, or Clute?" here.

See also the YouTube video:

Acoustics of Brass (lip reed) instruments Sample their sound files for tubes with and without a bell, mouthpiece, etc. One set of these sound files was used in Why You Hear What You Hear to study the effect of the bell, with somewhat different conclusions.

Clarinet acoustics

Excellent paper on clarinet acoustics from UNSW.

TEDx Carrot Clarinet

Saxophone acoustics

Flute acoustics

Trombone shock wave! (a little subtle on this schleiren movie, but there).

The Didgeridoo

This instrument gets a little shortchanged in Why You Hear What You Hear. The main reason is that I don't understand the incredibly strong interactions of lips, pipe resonances, and even vocalizations. It is perhaps one of the most complex instruments in existence, when played by a pro. The range of sounds is amazing and the pipe resonances are just the start of the story. I suggest you start with this video to see what I mean; move on to some William Barton (*this page is empty*) material if you are interested.

Nick Drozdoff and the trumpet

These and other YouTube videos by physics teacher and trumpeter extraordinaire Nick Drozdoff is essential viewing and listening for understanding the action of mouthpieces and bells in practical terms.
