1 Playing violin will not go by itself you know! As they say practice makes perfect. You don't have to practice an hour at once, just start with 15 minutes a day, and if you can keep up the good work, you can increase the practice time a bit every week or so.  Breaking up your practice is helpful.
Violins come in 8 main sizes. The size corresponds to the length of the body of the violin (not including the neck and scroll). The smallest common size is 1/16 (just 9 inches or 23 cm), and the sizes work their way up through 1/10, 1/8, 1/4, 1/2, 3/4, 7/8 and finally 4/4 or full size (about 14 inches or 36 cm). Generally speaking, you know if a violin fits if you can reach the notes comfortably with your left hand when holding up the violin. Most adults (and many children from around age 10+) will require a full-size violin. It depends on the length of your arm and what you feel you can hold comfortably.
