You must write 'foo' function. Maybe name it 'tune_generator'
or similar. It takes 'note' - number like 1,2,3.5 or 6
and return

You wrote " sin( _number_ *pi*220*t) + sin( _number_ *pi*440*t); "
ten times! It's better to use function than copy&paste code.
But of course you code will work.

So sound( [a,a,b,a,f,e,a,a,b,a,g,f], freqsamp ); and "pause" work
for you?
