Shell script music

Well, it seems I have the dubious distinction of being one of the few (if any) people to discover a way to play music using shell script. Observe the following snippet: /usr/bin/yes foo > /dev/dsp & SP="${!}"; sleep 1; kill "$SP" The more characters in the argument to /usr/bin/yes, the lower the tone. The length of the sleep argument determines how long the tone lasts, but a pre-constructed string of repeating "foo\n" components will do just as well, though you need about a thousand of them to last one second.
