Flutes
    7,000 B.C. in the journal Nature
    recording of 2nd flute from bottom of the diagram which you should "save link as" /zap/Flute7.wav and open in Snd
    Korean music examples presented by Unjung

(1) plastic replica assignment
(Use the tools and pipes in the Ballroom to craft a flute with no tone holes. The length can be the same as one you measure from the above article. The sharpened edge needs to be turned away from you or you'll hyperventilate for no good reason.)

(2) clm practice assignment
commands to run from terminal window:
    cd ~ (makes sure you are in your home)
    mkdir 220 (makes a new directory for the class)
    cd 220 (switches the window to that directory)
    mkdir flute (ditto)
    cd flute (ditto)
(from this next link, "save as" ~/220/flute/flute.ins) clm flute template (same thing Unjung has emailed to the class)
   xemacs flute.ins (start the editor on your copy of the code)
       c-x 2 (split window)
       c-x l (launch Lisp)
       :cl flute.ins (load the program code)
       select "with-sound" expression and evaluate with
       c-c c-r (which sends the expression to Lisp)
to look and listen, type in terminal:
    snd /zap/test.snd & (launches Snd in "background" mode)
...that's the file you can keep playing from...

(3) match the pitch of the synthesis to that of your flute (change the number from 220 Hz until it's right)
copy the /zap/test.snd to your directory to save it
use Snd to record a short tone from your plastic flute, save that too (different name)
turn in both .snd files according Unjung's directions coming in email
