The instrument is usually held by a loop of some form of thread or wire at the top curve, to enable the triangle to vibrate and it is struck with a metal rod called a "beater". The triangle theoretically has indefinite pitch , [ 1 ] and produces a plurality of overtones when struck with an appropriate beater.
The whirly tube, corrugaphone, or bloogle resonator, also sold as Free-Ka in the 1960s-1970s, is an experimental musical instrument which consists of a corrugated (ribbed) plastic tube or hose (hollow flexible cylinder), open at both ends and possibly wider at one end , the thinner of which is rotated in a circle to play.

His development preceded the sextant and was motivated by the need to create a superior surveying instrument. [3] The reflecting circle is a complete circular instrument graduated to 720° (to measure distances between heavenly bodies, there is no need to read an angle greater than 180°, since the minimum distance will always be less than 180°).
The first is an instrument shaped somewhat like a horn, in that it is formed in a circle. It has piston valves and is played with the right hand on the valves. Manufacturing of this instrument sharply decreased in the middle of the twentieth century, and this mellophone (or mellophonium) rarely appears today.
The criteria for classifying musical instruments vary depending on the point of view, time, and place. The many various approaches examine aspects such as the physical properties of the instrument (shape, construction, material composition, physical state, etc.), the manner in which the instrument is played (plucked, bowed, etc.), the means by which the instrument produces sound, the quality ...
A percussion mallet or beater is an object used to strike or beat a percussion instrument to produce its sound. The term beater is slightly more general. A mallet is normally held in the hand while a beater may be a foot or mechanically operated, for example in a bass drum pedal. The term drum stick is less general still but still applied to a ...

Brass instruments had their markings scribed directly into the brass. For marine navigation, the earliest examples were found around 1460.
