Analyzing the vibrating drum head problem explains percussion instruments such as drums and timpani. However, there is also a biological application in the working of the eardrum . From an educational point of view the modes of a two-dimensional object are a convenient way to visually demonstrate the meaning of modes, nodes, antinodes and even ...
Timpani (/ ˈ t ɪ m p ə n i /; [2] Italian pronunciation:) or kettledrums (also informally called timps) [2] are musical instruments in the percussion family.A type of drum categorised as a hemispherical drum, they consist of a membrane called a head stretched over a large bowl traditionally made of copper.

A timpani is a kind of kettle drum A cuica is a kind of friction drum. Barrel drums are normally one-headed, and may be open at the bottom. They bulge in the middle. Examples include the Dhak from eastern parts of India, bendre, made by the Mossi of Burkina Faso out of a large calabash, and the trong chau of Vietnam.

The thin, sensitive bottom (resonant) head is generally tuned higher than the batter head, to deaden the tendency for lengthy, ringing resonance. [1] The resonant head on a 14-inch snare drum is tuned to a range of 330–391 Hz (E 4 to G 4), depending on the overall tuning of the drum kit. Overtightening risks damaging the head; the recommended ...
Cymbals are usually notated with 'x' note heads, drums with normal elliptical note heads and auxiliary percussion with alternative note heads. [1] Non-pitched percussion notation on a conventional staff once commonly employed the bass clef , but the neutral clef (or "percussion clef"), consisting of two parallel vertical lines, is usually ...
Drums and timpani utilise exclusively (and only in Vienna) drumheads of goat skin. Because the radial modes of vibration are stronger with these skins Vienna timpani contain a much higher proportion of tonal components. The characteristics of the skins also determine the material used for the stick heads and grip.
