Actually either will work fine here.

But LIST is more appropriate.

What if SOUND's second argument was a list and therefore :notetime
had to be a list.

to AList :notetime
show (list 415 :notetime)
end

to ASe :notetime
show (se 415 :notetime)
end

AList [1 2 3]
[415 [1 2 3]]

ASe [1 2 3]
[415 1 2 3]

SENTENCE takes each element of each argument (which may be a list) and
places those elements in the output list. LIST just puts in what ever
you
give it. And in this case I know :notetime will never be a list so
the "extra" functionality SENTENCE provides is not needed.

Sometimes you want one behavior and sometimes the other but more often
than
not I want the behavior of LIST and always use it by default. It's also
less work for LOGO since it does not have to check if each argument is
a list or not, it just takes what ever you give it and puts it in the
list as
is.

SENTENCE is useful when you have groups of things you need to pull
together to
make a signal group of those things. Like 2 groups of words to form a
sentence :-)
