Now that you have a better idea of what to look for in a cello bow, it's important for you to know how to properly test a bow. There are a few tips that you should keep in the back of your mind while you're going out shopping for a bow.  First, you should know what you're looking for before you go out shopping for a cello bow. You'll need to figure out what your goals are. Whether you're looking for sound, agility, comfort, increased dynamics, no matter what your goal is, figure it out before you go shopping.  Plus, you should never pay attention to the flash and glam of a cello bow. There's a lot of cello bows out there that look beautiful, but this shouldn't be something you're shopping around for. Just like you wouldn't buy a cello just because it's pretty, you shouldn't buy a cello bow for the same reason.  Also, hold a bow in your hand whenever you can. You should feel like the cello bow you're holding is an extension of your arm. If it feels too heavy or too light, start looking for something else.  Keep in mind, it's going to take some time to find and figure out what the right bow for you is. Don't get discouraged if you don't immediately find the perfect bow for yourself.
