The cello is a bowed string instrument, which is also known as violoncello. A person who plays a cello is called a cellist or a violoncellist. In order to become a better cellist, here's some few tips
CLEANING YOUR CELLO
Your cello should be dusted off once a week, or just before a performance. Use a slightly damped cotton cloth. If you have rosin build up that won't come off with a damp cloth, use a very small amount of commercial violin polish. Do not spray your cello with silicone or wax.
STORING YOUR CELLO You should store your cello in a place where it's not likely to be knocked around. It is not necessary to put your cello in its case, unless you will be traveling with it. In fact, putting the cello in and out of its case more often than necessary will lead to unwanted scratches. If you will be away from your cello for several weeks or months, it may be wise to loosen the strings a little bit, but not all the way, lest the bridge fall off.
THE BRIDGE You should examine the bridge once a week to make sure that it is nearly perpendicular to the belly of the cello. If it slants too much it could snap in half, or be pulled over by the tension of the strings. You may adjust the bridge by loosening the strings slightly and grasping the bridge firmly with both hands, moving it into correct position.
THE ENDPIN When you place your cello down make sure the endpin is not sticking out where some careless person may kick it accidentally and send your cello flying. Some cellists sharpen the endpin to a fine point and stick it in the wood floor or carpet when they perform. This may be dangerous, and is bad for the floor. Instead I recommend an endpin holder with an adjustable strap, such as the Xeros Anchor
THE BOW Keep your bow in a safe place. Don't leave it where it may be sat upon or knocked to the floor. If you have a soft cello case, you should insert a pvc pipe into the bow holding pocket, just large enough for your bow, and this will protect your bow from a nasty knock when you are traveling. Do not engage in pretend sword fights with other cellists. Do not tap your bow on your music stand as a form of applause. You may very easily crack or break your bow. Loosen the tension on your bow when you are not using it. Never over-tighten your bow. Make it just tight enough that when you play the hair does not normally touch the bow stick.
PEGS There is no substitute for pegs that fit well. If they don't fit well, your pegs will either slip or stick. It doesn't help much to use chalk or peg slipping compound. Find a luthier to ream out the holes for your pegs, and make them work right. Gut or nylon strings may be fine tuned with the pegs alone, but steel strings require fine-tuners on the tail piece.
SCRATCHES Over the years some scratching is inevitable.If you have a very large nasty looking scratch, take your cello to a good luthier to be touched up. If your cello is a cheap student instrument, it doesn't really matter too much what you do to it. If it is an expensive antique, leave it for experts.
CRACKS It is not possible for the average cellist to fix a crack. Your cello may crack in the seams, or anywhere. Take it to a good luthier to be repaired.
CLIMATE
Do not store your cello in extreme hot or cold locations since your instrument is made of wood, it could crack, warp, or the varnish could melt. If you live in a dry climate, you may want to consider using a humidifier made for cellos .Weather, temperature and level of humidity affect every cello. Cracks may develop from either high or low humidity. A good expensive cello should not be used outdoors. Keep your cello at home in a room with a level temperature and humidity, if possible. Some cellist place humidifiers inside their cellos, through the f holes, but these are not really necessary or very effective. Get your cello a thick padded case that will help moderate temperature changes when you travel with it.
TRANSPORTATION Always be careful when you travel around. You can get a soft case if you don't travel around too much, you can get one with lots of thick padding to moderate temperature changes. Hard cases are heavier than bags, as long as it is hard on the outside, and grips your cello firmly on the inside.
