MY VIOLIN WONT TUNE!?

ok this is gonna take some practice, but heres what you do: as you tune your string with the peg, push the peg farther into the peg box with your hand. use your other hand to brace your violin so it doesnt go flying. this will take some practice. if this doesnt work, get an orchestra teacher, private lesson teacher, luthier (violin maker), or music store owner to help. most of the aformentioned people will have a kind of sticky liquid that the can put on your pegs to make them stick more
