The jug sound is made by taking a stovepipe ( usually a section of tin pipe, 3 " or 4 " in diameter ) is played in much the same manner, with the pipe rather than the jug being the resonating chamber.

If the resonating chamber is the correct size for the pitch being produced by the tongue, which means it has the correct volume of airspace to complete one full sound wave for that particular pitch, the instrument will be more efficient and louder.

The body has a long upper neck and a lower bowl-shaped resonating chamber made from a gourd or wood, usually covered with a membrane made from the skin of a lamb, goat or sometimes a fish, on which the bridge is set.

A vibrating string strung on a very thick log, as a hypothetical example, would make only a very quiet sound, so string instruments are usually constructed in such a way that the vibrating string is coupled to a hollow resonating chamber, a soundboard, or both.

At certain moments, he would bend his torso so that his bald head pointed toward the audience, aim his mouth at the resonating chamber within the bass and perform the low subharmonic growls of Mongolian throat-singing, which he had learned while staying at a Buddhist monastery in Japan during the early 1980s.
36.
At first the sound is a broad-spectrum " noise " ( i . e . " chiff " ), but those frequencies that are identical with the fundamental frequency of the resonating chamber, ( which depends on the fingering ), as well as its overtones to a lesser extent, are selectively amplified.
37.
The first informal instruments were relatively simple, like the " Gum-Horn ", made with a hose, a funnel and a trumpet's resonating chambers are made out of a large tin for processed ham and a paint can respectively, the " marimba de cocos ", a marimba made out of coconuts, and others.
