After you practice, or at the end of your clarinet lessons, you should take apart your clarinet and clean it. This will prevent damage from moisture or contaminants. It will also prevent your clarinet from getting accidentally knocked over or otherwise damaged.
During assembly you worked from the bottom to the top of the clarinet. In disassembly you’ll do the opposite, working from top to bottom.
Gently unscrew and remove the ligature. Be careful not to chip the reed.
Carefully take off your reed and place it back into its plastic sleeve or reed case.
Separate the mouthpiece from the barrel using a twisting motion.
Place the ligature back on the mouthpiece, slip the mouthpiece cap on the mouthpiece, and then place them back inside the case.
At this point, especially if you just had a long practice session, you should clean your clarinet. Grab your swab, and feed the end with the string and weight into the clarinet’s bell; flip it over to pull the string out. Do this as many times as is necessary to dry the clarinet.
Twist off the barrel from the upper joint and place it in your case.
Twist off the upper joint. Again, be mindful so that you don’t damage the keys and connecting parts. Place the upper joint in your case.
Twist apart the bell and lower joint and place them in your case.
Excellent work! Your clarinet is now taken apart and safely stored. In case you missed it, learn how to put your clarinet together.
