Q: with an electric tuner. Find an electric tuner for cello at a music supply store. You can attach the tuner to the bridge of the instrument or you can download a tuning app on your cell phone. Bow each string consistently and with the same pressure one at a time and follow the instruction on the tuner to check that the string is in tune. Sitting behind your cello in the proper position, the last string on the right is “C.” It’s your thickest cello string. Pluck the string with your right pointer finger (both left handed and right handed people cluck the cello the same way). Make sure your thumb is positioned at the end of the fingerboard to provide stability. Never pluck far up the fingerboard!  The note is “open” because you are not pressing down with your left fingers on the string to play it. The string itself is in the note of “C.” The cello “bridge” is the piece that sticks up about halfway down the cello and holds the stings in place. The fingerboard is the long black-colored piece that runs down the front of the cello’s neck, and is where you put your fingers to play other notes. The second string from your right is called the “G” string. It is the second-thickest string on the cello. Pluck this string with your pointer finger on your right hand, and rest your thumb on the side of the fingerboard.  Plucking the string is called pizzicato The third-thickest string, located next to the “G” string, is the “D” string. Pluck the string to see what “D” sounds like. The last string on the left, and the thinnest string, is your “A” string. Pluck the “A” string to see how it sounds. A good way to remember the string notes on your cello is the sentence “Cats Go Down Alleys” starting from your right with the thickest “C” string.
A: Tune your cello Try an open “C” on the thickest string on the right end. Play an open “G” on the second string from your right. Try an open “D” on the third string in from your right. Play an open “A” on the thinnest string on the left end.

Article: If you feel your pulse rate quickening, or your bicep flexing, you might be brushing too hard.  Enamel is broken down via "toothbrush abrasion" and exposes dentin.  If you're brushing vigorously, it could lead to increased tooth sensitivity and receding gums. Teeth whitening products often use hydrogen peroxide which wears down the enamel and could penetrate into any existing decay or inner areas of the tooth.  Aside from potential pain and sensitivity, whitening does not affect various dental restorations such as crowns or porcelain veneers, which could cause multi-colored teeth, negating any vanity aspects of the procedure. Symptoms vary according to the nature, frequency and duration of excessive clenching and grinding. Aside from general sensitivity, grinding can include pain in the teeth, chronic muscular facial pain with tension headaches, flattened tooth surfaces, micro fractures of the tooth enamel, broken or chipped teeth, pain in the jaw joint that cause restricted opening and difficult chewing. If grinding is an old habit, you might usually have an increased development of the masseter and temporal muscles that change the look of your face, making your face seem muscular and always tense. Post dental treatment sensitivity can be created by inflammation and very subtle movement within and between teeth.  If you recently had a procedure done at the dentist, there is a possibility of sensitivity. Acidic foods and drinks (e.g. tomatoes, pickles, fruits, soda) can wear down enamel if consumed regularly and in abundance.  They may also be the culprits behind some acid reflux, which can also erode enamel.
Question: What is a summary of what this article is about?
Brush your teeth. Stop using whitening/bleaching products. Cease grinding your teeth. Review your calendar. Diagnose your diet.

Article: Ice is only really effective for the first 48 hours. After icing the hickey for 48 hours, you'll want to switch to a warm compress for the remainder of your treatment regimen.  Ice heals the broken blood vessels, but heat will help increase blood flow to the area. This will facilitate healing and the reabsorption of blood.  Use a hot water bottle or a microwavable heating pad.  Do not apply heat therapy for longer than 20 minutes at a time. Don't use heat therapy if you have diabetes or poor circulation. In addition to applying a warm compress, massaging a bruise like a hickey can help facilitate blood flow to the site of the injury. Common methods of massaging a hickey include rubbing it with your hands or applying pressure using:  a toothbrush with stiff bristles  a pen cap  the cap from a tube of chapstick Icing, heating, and massaging the skin will all help the bruise heal, but you may want to treat the skin in order to make the physical mark disappear more quickly. No skin treatment will provide instant results, but will help speed up the healing process. Common skin treatments include:  aloe vera  Arnica salve  Preparation H  taking vitamins C, E, and K supplements  taking bilberry extract  taking bromelain
