Tom
See also: Tom (homonymy)
A Tom is one of the elements of a battery. One generally finds three on the standard configurations (historically, 12 13 and 16 inch S) but one can add some about as much as one wishes. It is about a wood barrel on which is tended a synthetic skin or, more rarely, animal, that one strikes using the rods. The toms are in general used to connect two Rythme S or to support passages rates/rhythms.
Principle
The was is bored, on its circumferences inferior and superior, of a series of holes which cross of the screws directed towards outside. On those come to set shells in which other screws, to square head, will come to fit into right angle. The skin of striking is posed on the higher face of the barrel and the skin of resonance on the posterior face. They rest on the Chanfrein S (or edges) of the barrel. On the skins, one places two circles of stainless steel, copper or of wood: their diameter is slightly higher than that of the skins and is equipped with a number of perforations are equivalent to those of the barrel. The screws cross them and fit in the shells, then making possible the Accordage of Tom.
It is necessary to use a specific key to tighten or loosen the screws of tuning. The vast majority of the manufacturers uses the same format of screw. One can note that the German manufacturer Sonor has, during several decades, selected to use a particular format of screw, problematic choice in the event of loss. To mitigate this disadvantage, since the beginning of the Years 2000, their new models are delivered equipped with standard screw.
Composition and completion
The materials of manufacture and the level of completion of the toms vary according to the manufacturer and the range of price. They share the characteristics of the other elements of percussion constitutive of a traditional battery, namely the large case and the clear case.

Fixing
There exist various types of fasteners, most widespread consisting of an articulated tube returning in two openings, one practiced on the circumference of Tom, the other on the upper part of the Grosse case. Other models use, as an articulation, a ball into synthetic very resistant enclosed between two moving parts, called Rotule , which allows a positioning of the more precise barrel and rapid because not calling upon the key of adjustment.
The toms low, whose diameter generally varies 14" with 18" , according to their depth, either are equipped with fasteners in the same way standard than the toms media and are then fixed on a dedicated tripod or a foot of Cymbale, or equipped each of three feet sliding in the direction height of Tom in order to make them stable and easily adjustable.
Since the years 1990, one also finds suspensions which are fixed on the circle holding the skin: they make it possible to Tom to longer resound, improving thus considerably the Sustain .
