A verrophone ("glass-euphonium") is a musical instrument, invented in 1983 by Sascha Reckert, [1] which, "uses tuned glass tubes," [2] open at one end and arranged in various sizes (usually in a chromatic scale, arranged from large to small, like the pipes of a pipe organ).
A micro perforated plate (MPP) is a device used to absorb sound, reducing its intensity. It consists of a thin flat plate, made from one of several different materials, with small holes punched in it. An MPP offers an alternative to traditional sound absorbers made from porous materials.
A crystallophone is a musical instrument that produces sound from glass. One of the best known crystallophones is the glass harmonica, a set of rotating glass bowls which produce eerie, clear tones when rubbed with a wet finger. Musical glasses, the glass harp, were documented in Persia in the 14th century. [1]
Cups or wine glasses are filled with varying levels of water. The glasses may either be struck with a dampened stick to produce a percussive sound, or a player may moisten their fingers and rub the rims of the glasses to produce a sound.

The glasschord was invented circa 1785 [2] by physicist [3] M. Beyer of Paris. [4] [5] It creates sound by using cloth covered wooden hammers to strike glass tubes laid on a cloth strip, with no dampeners.
Metal rods are embedded in a heavy plate to form the elements. Each metal rod is accompanied by an attached glass rod. The metal rod's length, weight and position at the equilibrium point determine the sound's pitch. The glass rod is gently stroked with a wet finger to produce sound.
A "stem" (a tube with a small cup) may be inserted into the mute, which changes the instrument's sound and path of airflow. [22] [29] The mute is made of metal (usually aluminum or copper) and has a cylindrical or bulbous shape; [23] mutes of the latter type are sometimes called "bubble mutes". [35]
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound.Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to their disc-shaped successor, these hollow cylindrical objects have an audio recording engraved on the outside surface which can ...
