INPUT ARTICLE: Article: Before you assemble your saxophone, you need to be able to identify all of the parts. The main parts of the sax are the body, neck, mouthpiece, reed, and ligature. Your reed goes in your mouthpiece and is the part of the saxophone you blow into to play it. The neck of your sax is the part that connects to the mouthpiece and to the main body of your saxophone. The body of your saxophone is the large part that contains all the buttons you hold in order to play different notes. The ligature is a metal sheath that fits over your mouthpiece and keeps your reed in place. While you assemble your saxophone, refrain from pushing or pulling on parts because they may bend. Your reed needs to be wet when you play the saxophone. As you start to assemble your saxophone, keep your reed in your mouth to put the required moisture on it. You can also practice blowing through your reed as you put together your saxophone. Slide the mouthpiece about halfway over the cork. Make sure that the open side of the neck and mouthpiece are both facing up. You may need cork grease to slide the mouthpiece over the cork. A twisting motion may also help you attach the mouthpiece. Gently push the reed onto the mouthpiece, so the top of the reed and the top of the mouthpiece meet each other. It's important that your reed is wet, or it won't hold in place. Handle the ligature with care and make sure not to damage the tip of your reed. Slide the ligature over the reed and position it towards the bottom of the reed. Tighten the screws to hold the reed in place. Once you have the reed attached, you should twist the mouthpiece so the reed is facing downwards. Take the body of the saxophone and thread your neck strap through the hook on the back of the saxophone. You should hold the saxophone on the bottom with your dominant hand to keep it in place as you do this. Carefully twist the neck into the hole on the top of the body of your saxophone. After the neck is secure and facing towards your mouth, tighten the screws. There may be a plug in the top, so take that out first if you have one.

SUMMARY: Identify all the parts of your saxophone. Put your reed in your mouth. Attach the mouthpiece to the neck of your saxophone. Slide your reed onto your mouthpiece. Slide the ligature over the reed. Attach the body of your sax to your neck strap. Attach the neck to the top of the body and tighten the screws.

INPUT ARTICLE: Article: Give the mattress a liberal dusting of baking soda, especially if it has not been cleaned in awhile or has a strong smell. Cover the entire surface of the mattress with an even layer of baking soda. If there is a particular area that has a strong smell, sprinkle more baking soda on it to neutralize it. Moving the mattress next to a window that gets direct sunlight is ideal, as the heat from the sun can help the baking soda work more effectively. If you really want the baking soda to kick into high gear, you can place the mattress outside in direct sunlight. Make sure there is no rain the forecast so the mattress does not get wet overnight. Give the baking soda time to settle in and do its job. Keep others away from the bed so it is not disturbed. Make arrangements to sleep elsewhere for the night so the baking soda can sit.

SUMMARY: Sprinkle 1-3 cups (208-624 g) of baking soda on the mattress. Put the mattress in direct sunlight. Let the baking soda sit for 24 hours.
