INPUT ARTICLE: Article: To know what notes you should be singing in an opera role, you'll need to be able to read music. You can teach yourself how to read music using books or online tutorials, or take lessons through a vocal instructor. Search "how to read music" to find online resources and instructors near you. Or, check out books on reading music from your local library. Learn the basics by studying the Staff, and then learn the notes on the Treble and Bass Clefs. Get used to the different types of notes and what they mean, and then move onto learning about more complex features like meter, time, and melody. It is helpful to understand the meaning of what you're singing in opera, because operas are essentially dramas that are sung. You'll also want to be sure that you're pronouncing words correctly. Try using a language-learning app or checking out books at the library to become familiar with the basic grammar and vocabulary of the language of your favorite opera. Browse videos and audio clips online and check your local library for recordings of operas. As you listen to these recordings, follow along with the written script. Observe the movement and facial expressions of the opera singers to help you become familiar with operatic acting techniques. If you can, find operas that provide English translations to help you better understand the story.

SUMMARY: Learn to read sheet music. Familiarize yourself with Italian, German, or French. Watch videos of operas while reading the words.

INPUT ARTICLE: Article: You will be working with lye, which can be dangerous if not handled properly. Put on a pair of goggles, a mask, rubber gloves, and along sleeved shirt. Have an accurate, digital scale ready. Your measurements must be precise, or they may not saponify properly. You will use the scale to measure everything, including the liquid ingredients. This recipe will make a lot of soap. You can resize this recipe to make a smaller amount, but you will need to use an accurate soap-making calculator to convert the amounts. Measure and pour 38 ounces (1123.79 grams) of cool water into a large pitcher first. Next, measure out 15 ounces (425.25 grams) of lye and sprinkle it into the water. Let it heat to 200F (94C), then stir with spoon for 30 seconds to dissolve the lye. Never add water directly into lye, as this will cause the lye to erupt. Use a pitcher designated specifically for this purpose. Do not reuse this cup for anything else. There are different types of lye used for soap making. You want to use Sodium Hydroxide (NaOH). Cover the pitcher with lid, then place it some place where it won't tip over. Let the solution cool down to 100 and 125F (38 to 52C). This can take 30 min to 2 hours. You will need: 2 pounds (907.2 grams) coconut oil, 2 pounds (907.2 grams) olive oil, 1 pound 6 ounces (623.7 grams) soybean oil, 1 pound 2 ounces (510.3 grams) palm oil, 0.8 ounces (22.68 grams) coco butter, and 0.4 ounces (11.34 grams) shea butter. You can do this in a large pot or in a double-boiler, if you can find one big enough. Heat them up to somewhere 100 and 125F (38 to 52C). Wait for the oil and butter mixture to cool down to at least 125F (52C), then pour in the cooled lye solution. Mix everything together using a stick blender set to low speed. Keep the blender near the bottom of the pot. Be careful so that the mixture doesn't splash. It hasn't saponified yet, so it is still caustic and can cause burns. Trace happens after 3 to 5 minutes. It will turn runny and pudding like. If the blender leaves marks on the surface when you pull it out, you're at trace. Be prepared to work quickly during the next few steps as the mixture will start to harden. Mix about 1 teaspoon of red iron oxide dye with tablespoon of glycerin or olive oil. Stir it into the soap mixture until it is almost the same color as calamine lotion. Don't worry if the mixture looks a little dark. The zinc oxide in the next step will help lighten it up. You may not end up using all of your prepared dye. You will need between and cups (663.28 and 994.91 grams). Keep adding the zinc oxide until the mixture is the same color as calamine lotion. Combined with the iron oxide, the zinc oxide will help make your skin less itchy. Both zinc oxide and iron oxide are important ingredients in calamine lotion. You will need 4 ounces (113.4 grams) total. You can use any fragrance or combination of fragrances you what. A combination of chamomile, lavender, and tea tree would work especially well. You can also use several smaller molds instead. Some molds will need to be lined with parchment paper or plastic wrap first. Other molds, usually those made from silicone, do not need to be prepared. Tap bottom of mold against counter to release any bubbles. Some people like to leave the top of the soap bumpy. If you want it smoother, run a spoon over it. Wrap some plastic wrap over the mold(s) first, then cover them with blankets and quilts. This will keep the soap insulated while it hardens and saponifies. you can take a peek every now and then. If you see a crack forming on the soap, it's getting too hot. Remove the blankets. Remove the soap from the mold(s) first, then cut it into bars. Spread the bars out on a baking sheet. Place them some place where they won't be disturbed. Let them cure for 4 weeks. After 4 weeks, the soap will have saponified. It's ready to be used!

SUMMARY: Protect yourself and your work surface. Prepare the water and lye solution. Set the lye solution aside so that it can cool down. Melt the oils and butters. Stir the cooled lye solution into the oil and butter mixture. Wait for the mixture to trace. Add the prepared dye to the mixture. Stir in the zinc oxide. Stir in the essential oils. Pour the mixture into an 8-pound (3.6-kilogram) soap making mold. Cover the soap with plastic wrap and blankets, then wait 24 hours. De-mold, cut, and cure the soap.

INPUT ARTICLE: Article: This should ensure that you use the cleaning methods in every bit of the zipper possible. Use your fingers to hold the zipper by the pull and tug up and down. Try using needle nose pliers to hold the zipper by the slider or "car" and try to move that up and down. Don't be too rough with it so that the zipper doesn't break or get off track. If the zipper is stuck, try rubbing it with beeswax or a block of paraffin wax before cleaning it. You can find such items at health stores, hardware stores, and some supermarkets. If you're outdoors without access to additional supplies, try using a bar of soap or candle wax to loosen the zipper, if you have one of those on hand. Sometimes salt will dissolve in freshwater. Wash the zipper under a tap or hose. Alternately, you can use a bucket of warm water. Try using a small wire brush to scrub the zipper with water. Make sure that the brush is small enough or positioned so that the brush does not damage the material the zipper is attached to. Use a non-detergent soap solution in a bucket of warm water. Use a stiff brush to scrub the zipper. Make a fresh soapy water solution by adding five tablespoons of soap powder to 20 liters of water. Stir it in a bucket until it's sudsy. Dispose of any leftover solution once finished.

SUMMARY:
Open the zipper as much as possible. Use beeswax to loosen the zipper. Rinse the zipper thoroughly with freshwater. Wash the zipper with a soap solution.
