A slide is a part of a wind instrument consisting of two (or more) pieces of tubing fitted one closely inside the other, and used to vary the overall length of the tube, and therefore the pitch of the instrument. Often two sets of tubes are used, with a U bend attaching them; this arrangement is called a single slide. A double slide, where two U-shaped slides are braced together and move on four inner tubes, is found on the B♭ contrabass trombone.

Slides are used in three main ways:

In instruments such as the
slide saxophone was invented in the 1920s by Chicago instrument maker Reiffel & Husted.^[1]

On most brass instruments, a tuning slide is used to adjust the main pitch of the instrument before playing. A modern double or triple french horn has several tuning slides, which are sometimes moved during performance.
In instruments such as the
trigger
while playing, to correct the pitch of the note selected by the valves.
