Quarter as a soloist with Friends or in a recorder ensemble.
If your recorder is constructed with two or three pieces,
you can clean each piece by using your cleaning rod with a soft
cloth to gently swab the insides.
If your recorder is made of plastic, not wood,
you can occasionally clean the mouthpiece by dipping it in warm,
soapy water and rinsing it with clear water.
Let it dry completely before playing.
The next time you play your recorder,
check to be sure that the pieces are connected and lined up
properly.
Congratulations, you're off to a great start playing there.
