On Wedneday a child handed me a new violin which had recently been purchased at a local supermarket. On opening the case I found the bridge lying flat wrapped in tissue paper and a 'manual' (small sheet of paper with a set of instruction) on how to mount the bridge. Needless to say, the wafer-thin piece of wood snapped at the first attempt to tighten the unbelievably thin strings (which will almost certainly snap next time).
This 'manual' also had instructions for use of the bow:
"Before using the bow, you have to wax it.
Make sure that the bow is covered with wax before use.
NOTE: The faster you move the wax on the bow, the hotter the wax gets, and it will be easier to use."
