[chuck-users] Begin the beguine

[Joel Matthys]

I'd like to point out that "count" is a variable name, not a built-in 
ChucK thing. In this example, "count" is just the name someone has 
chosen to keep track of a number that keeps increasing by 1.

You might want to look at the ChucK tutorials I made for our Intro to 
Electronic Music course here at the University of Cincinnati. There are 
7 tutorials that start from a simple SinOsc and introduce variables, 
functions, STK instruments, and sporking. They were intended as notes to 
accompany the class but they might be useful.

I uploaded them here:
