In one sentence, describe what the following article is about: Get an oven thermometer and use it to see if your oven is reaching the right temperature. These are usually fairly cheap to purchase and can save you many batches of burnt cookies and other items. Darker sheets hold in the heat, so you may need to reduce the baking time. Shiny sheets reflect heat outwards, so you may need to add a minute or two. If you find that your cookies are consistently burnt on the bottom, try lowering the baking temperature by about ten degrees. Cookie sheets without side rims make it easier to slide your cookies off when they are done. They also give you room for more cookies per sheet. To keep your sheets from bending in the oven, go with a heavier metal. Get a paper towel, dip it in shortening or butter, and rub it on to your sheets. Your goal is to create a thin layer of grease. You can also use a non-stick spray. Otherwise, you can just place a piece of parchment paper on the cookie sheet. Place this single sheet on the middle rack of your oven. If you cook more than one sheet at once, you'll likely overcrowd your oven and alter the baking time. However, if you choose to do two sheets, rotate them to ensure even baking. After you take your cookies out of the oven, let them sit on the pan for 3 to 5 minutes. Then, lift each cookie gently with a spatula and transfer it over to a wire rack. The wire rack should sit at least 3 inches (7.6cm) off the countertop or moisture will form under the cookies. If you are cooking in higher altitudes, then you may need to change your ingredients slightly and monitor your baking times even more closely. Start by experimenting with decreasing the butter, shortening, or sugar amounts if your cookies end up too large and burnt. Your baking time might also vary.
Summary: Check your oven's temperature. Adjust the baking time and temperature depending on your cookie sheet. Get rimless sheets for ease of use. Grease your sheets before baking. Bake only one sheet of cookies at a time. Let cookies cool on the pan. Make adjustments for higher altitudes.

Problem: Article: In order for you to make the right sounds with your slide, you need to learn to mute the strings above where your sliding. This will keep the strings from unwanted vibrations and keep them from producing unwanted sounds. To do this, gently press your fingers on the strings. Use just enough pressure to keep the strings from making unnecessary noises as they vibrate. To play your slide correctly, you need to make sure you are pressing it in the right place. You should not press the string under or above the fret because the note will sound flat.  You should also not press the string into the fretboard. Even if your eyes say that you are directly above the fret, listen to the note. If it sounds flat or wrong in any way, move your slide up and down until it makes the right note. To start learning to slide, pick a note on your guitar. Muting the other strings with your non-slide fingers, press gently with the slide and then move it up and down the strings to make the sliding sound. You can start slow to get a feel for the different technique of playing and motions needed to play with the slide on.  If you are using the slide on your middle finger, you will not be able to mute the strings. Just apply gently enough to get the sound you want. Try playing songs you are familiar with using your slide to get used to the different feel of the technique. When you use a slide, you should not press too hard on the strings. This will make the strings touch the fretboard, which will cause your guitar to make strange, unpleasant sounds. Move your hand up and down to gauge how hard you are pressing.  If it's hard to move the slide, you should lighten your pressure. The more you move your hand around, the better feel you will have for the strings. As you play note after note, the strings will continue to reverberate. If you slide up the string to your next note, all the notes in between will play as well. To avoid this, mute the strings between different notes using your other hand.  You can use the finger that you are picking with or the heel of your hand to help mute the strings. Sliding between the notes is part of the slide sound. However, if you slide between the notes you play, the sound can get overwhelming or redundant. Practice different songs to decide when to slide and when you should mute the strings.
Summary:
Mute the strings above your slide. Press the slide directly above a fret. Slide into the notes. Use gentle pressure. Mute the strings between notes.
