Your misusing [ ], [ ]'s are for a literal list of items.
You want to build a list and put what you need into it.

Try this:

make "notetime 100
show [415 :notetime]
show (list 415 :notetime)

So this is your fix.

to Ab :notetime
sound (list 415 :notetime)
end

It's a common misunderstanding in Logo.

You might want to join the logo-l mailing list.
See bottom of MSWLogo web page to see how to join.
