all particles of dust from under the keys. A very slight application
of oil applied to the bristles will brighten the wood.
The keys, if tarnished, should very carefully be cleaned with
a high grade silver polish or jeweler's rouge.
(5) All pads should be at least 1,8 inch from the keyholes
when open, as they will otherwise draw water into the holes.
(6) If there is a keyhole that continually draws water, a
small coating of vaseline should be applied inside the hole.
This will prevent water from entering.
(7) The sudden exposure of any wood instrument to cold,
heat, or extreme variations of temperature should be avoided,
as this is the chief cause of cracking.
(8) It is impossible to obviate entirely the shrinkage and
change of the wood. New wood often shrinks to such a degree
as to put the key action entirely out of order; such condition
does not necessarily place the instrument out of commission.
By removing keys and carefully filing the posts or key shafting,
all binding can be eliminated. Such work, however,
should be done only by an expert.
(9) Should the keys stick, through neglect, the use of a
screw driver and a little pure olive oil added for a few minutes
on the screw and springs will very often remedy the
difficulty.
(10) If the joint rings become loose, they can be forced on
with a little paper under them. This treatment also applies
to the ring on the bell joint.
(11) A wood-wind instrument, if not used, will seldom crack
if properly stored and properly handled when again put into
service. The cause of cracking in most cases is that, when
playing, the instrument is warm and moist on the inside.
This causes it to swell on the inside, but the outside being dry
and cool resists this expansion, thus creating two forces
opposite to each other. If the expanding force is sufficiently
strong, the instrument will crack.
(12) It is extremely important that the barrel joint on a
clarinet be kept free and movable. When a clarinet cracks,
it usually does so in the upper joint, due to the fact that it is
closer to the source of heat (the player's breath), and is
subjected to more extreme variations in temperature.
(13) All joints of flutes and piccolos should be thoroughly
greased and the head joint stopper so lubricated as to make
