In one sentence, describe what the following article is about: Double-click the Excel document to open it. It's in the left side of the green ribbon that's at the top of the Excel window. Doing so will open a toolbar below the ribbon. It's in the Group drop-down menu. If you receive a pop-up box that says "Cannot create an outline", your data doesn't have an outline-compatible formula in it. You'll need to manually outline the data. Click the [-] button at the top or on the left side of the Excel spreadsheet to hide the grouped data. In most cases, doing this will only display the final line of the data. Click Ungroup to the right of the Group option, then click Clear Outline... in the drop-down menu. This will ungroup and unhide any data that was minimized or grouped previously.
Summary: Open your Excel document. Click the Data tab. Click Auto Outline. Minimize your data. Clear your outline if needed.

In one sentence, describe what the following article is about: A flute that is out of tune might be flat or sharp. Knowing if your flute is flat or sharp will determine how you get it back into tune. "Flat" refers to a pitch that is slightly lower than it is supposed to be. While a note can be flatted (B versus B-flat), in this case it's much less of a difference: simply a slight lowering of pitch. "Sharp" means that your pitch is slightly higher than it is supposed to be.While a note can be sharped (B versus B-flat), in this case it's much less of a difference: simply a slight heightening of pitch. When it comes to flutes, the length of the body of the instrument is one factor in determining whether it plays a particular pitch in tune. The longer your flute, the lower its pitch tendency will be. As you adjust a flute's length through headjoint adjustments, you change its overall pitch. A flute is a complex instrument, and tuning it differs significantly from the process required for other instruments. The only modification a player should generally make it with the headjoint position itself. If the scale is out of tune with itself throughout the instrument, a replacing or replacement of the headcork/crown could be necessary. If possible, do not do this on your own (as described in step 3), and take it to a certified repair person. The flute's crown is the cap located on the end of the flute nearest the lip plate and embouchure hole. The crown looks like a small metal cap, but it is actually attached to a headcork assembly that is inside the headjoint. Once you adjust it once, leave it in place. Don't tighten or loosen it again. The headjoint is the first of three joints that holds the flute's body together. It includes the lip plate. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/17\/Tune-a-Flute-Step-4.jpg\/v4-460px-Tune-a-Flute-Step-4.jpg","bigUrl":"\/images\/thumb\/1\/17\/Tune-a-Flute-Step-4.jpg\/aid4782951-v4-728px-Tune-a-Flute-Step-4.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/">Creative Commons<\/a><br>

<\/p><\/div>"} Generally, ensembles will perform at A4=440; most flutes are designed to play at this (and a small range of other) pitch levels. After tuning your A, using a chromatic tuner, play a mid-range note (such as G) without looking at the tuner. Once you have the note established, glance at the tuner to be sure it is not playing flat or sharp. If it is playing flat or sharp, the headcork could require adjustment or replacement.
Summary: Know the terms. Know how your flute's size affects its tune. Understand the two ways to change a flute's tuning.

In one sentence, describe what the following article is about: This stretch is very useful at loosening up your groin and inner thigh muscles, which are crucial to executing a Chinese split. Sit on the floor with your back straight. Bend your knees and bring the soles of your feet together in front of you. Slowly pull your heels in towards your groin. Try to get your heels as close to you as you comfortably can, and keep your hands gripping your ankles. Gently flex your knees down until they are touching the floor, or as close to the floor as you can comfortably get them. You can use your elbows to push your knees downward. While exhaling, bend forward at the waist, and try to get your chest as close to the floor as possible. Hold the position for 20 seconds, then release it. This yoga position will help you stretch and loosen the muscles in your groin, calves, and quads, all major muscle groups needed to do a Chinese split. Begin by lying flat on your back. As you exhale, pull your knees up towards your stomach. While holding the outsides of each foot in your hands, open your knees just past the width of your abdomen, and pull your knees towards your armpits. Try to keep your shins perpendicular to the floor. Hold the position for as long as you comfortably can (around 10 to 30 seconds should be sufficient), then release the pose. This yoga pose might be one of the best stretches to prepare your body for doing Chinese splits. Take it slow, though, as this position may be strenuous for first-time practitioners. Begin by entering a staff pose. Sit on the floor with your back straight and your legs fully extended in front of you, with the insides of your feet touching. Spread both legs outward. Try to form both legs into 90 degree angles with your hips. Slide your bottom slightly forward while keeping your legs spread to help push your legs as wide as you can comfortably spread them. While keeping your knee caps pointed upward, stretch your hands forward between your legs as far as you can go without bending at the waist. Hold the pose for around one minute, or as long as you comfortably can. Then release the pose.
Summary:
Do a butterfly stretch. Practice the Happy Baby pose. Do a wide-angle seated forward bend.
