Query to show all ID's except the ones that have a specific instrument

So I have a table which looks like this:

What would be the best query to exclude every "stuknr" that has atleast 1 "saxofoon" in the "instrumentnaam" column?

>Solution :

To select all stuknr where there is not stuknr with a saxofoon:

SELECT *
FROM table
WHERE stuknr not in (
   SELECT stuknr 
   FROM TABLE 
   WHERE INSTRUMENTNAAM = ‘saxofoon’)
;
