violin

Tuning can be difficult for beginners, it helps to use an electronic tuner. Bring the string to the correct pitch by turning the tuning peg. When the string is tuned, push the peg into the peghead so it holds the string firmly in place (peg compound can be used to stop slipping pegs). If the violin has fine tuners the strings can then be fine tuned at the tailpiece.

The violin bridge is held in place by pressure from the strings, it is not glued in place.
The bridge sits vertically, standing straight upwards from the violin body. The base of the bridge should align with the notches in the F-holes. The lowest side of the bridge should be placed under the E string (thinnest). When adjusting or putting a bridge on the violin, slightly loosen the violin strings, then hold the bridge in place while tightening the strings.

Violin bows need 'rosin' to produce a sound. Rosin gives the bow hair friction so it can grip and vibrate a note properly on the strings. Without rosin, the bow will slide across the violin strings without producing a tone. Rosin usually comes in a round or oblong cake of hard resin.

To apply rosin, hold the cake at the base of the bow hair, rub back and forth a few times at the base, then go all the way to the tip, rub the tip back and forth a few times then return to the base. Repeat this several times.

The rosin will leave dust on the violin, which you can wipe off with a cloth after playing.
To much rosin will cause clogging in the bow hair which will make a raspy sound on the strings. A light dust through the bow hair is usually enough (trial & error is best)

Tighten the bow hair with the tension screw at the base of the bow. Do not over tighten the hair, or leave it too loose so it presses against the bow stick. (the picture above is at correct tension)
