I played for many years when young. *IF* the pads that cover the holes are ok...and *IF the cork where the sections slide together are ok, then you can try it. The cork needs 'occasional' cork grease...comes in a little tin and is cheap...any music store. Get a couple light reeds..1 or 1½, as said above.

Now...be warned...clarinet requires getting used to, as the lower lip is pressed against the lower teeth, and the mouth can get tired....but this is not a big deal just to see if it will play.

I, personally, would take the instruments to some local player and have them evaluated....a school might know a teacher.

Unlike recorder..(which I have played for many years)...clarinets are not so easily learned on your own. There is much practice in embrochure,(holding your mouth right) fingering,(covering ALL the holes properly) and breath control.

All that being said, we have a woman in our folk circle who plays clarinet with us a lot, and makes it work beautifully.
