1. Loosen the strings slightlyTo avoid snapping a string while placing the bridge, loosen the strings slightly. You loosen violin strings by turning the tuning knobs on the end of the violin. | 2. Place the bridge between the F-holesWhen you slide the bridge under the strings, make sure it's between the two F-holes. The bridge should be placed at roughly the midway point of the f-holes. | 3. Make sure the bridge is standing at a 90 degree angleThe side of the bridge facing the violin's tailpiece should stand at 90 degree. The other side of the bridge should be sloped forward slightly. If not, put it in place backwards. You'll have to remove the bridge and start over. | 4. Tighten the stringsRe-tighten your strings to keep the knob in place. Gently turn each knob on the bottom of the violin. It's a good idea to use one hand to hold the bridge in place while tightening the strings, to prevent it from falling over. |
