Gubal (instrument)
The Gubal is a musical instrument developed by the Swiss company ''PANArt Hang Manufacturing Ltd.''. It is a vessel made of PANArt's patented ''Pang'', a deep drawn sheet steel permeated by iron nitride needles. Pang was developed by PANArt for steelpan construction in the middle of the 1990s. Examining the characteristics of their new material the PANArt tuners Sabina Schärer and Felix Rohner created a number of different ''Pang instruments''. In the year 2001 they introduced the ''Hang''. The Gubal was the first Pang instrument that was developed after the Hang. It was introduced in Summer 2013 on occasion of the 20th anniversary of PANArt. The name Gubal is registered as trademark for musical instruments by PANArt Hang Manufacturing Ltd. The Gubal has some similarities to the Hang but also some important differences that caused its developers to give the instrument a new name. Description Like the Hang the Gubal is played with the hands and combines the sounds of a ring o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Musical Instrument
A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The date and origin of the first device considered a musical instrument is disputed. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 50,000 - 60,000 years. Some consensus dates early flutes to about 40,000 years ago. However, most historians be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Drawing
Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention. The process is considered "deep" drawing when the depth of the drawn part exceeds its diameter. This is achieved by redrawing the part through a series of dies. The flange region (sheet metal in the die shoulder area) experiences a radial drawing stress and a tangential compressive stress due to the material retention property. These compressive stresses (hoop stresses) result in flange wrinkles (wrinkles of the first order). Wrinkles can be prevented by using a blank holder, the function of which is to facilitate controlled material flow into the die radius. Deep drawing presses, especially in the Aerospace and Medical industries, require unparalleled accuracy and precision. Sheet hydroforming presses do complex draw work.

Iron Nitride
Iron nitrides are inorganic chemical compounds of iron and nitrogen. Chemical properties Iron has five nitrides observed at ambient conditions, Fe2N, Fe3N4, Fe4N, Fe7N3 and Fe16N2. They are crystalline, metallic solids. Group 7 and group 8 transition metals form nitrides that decompose at relatively low temperatures – iron nitride, Fe2N decomposes under loss of molecular nitrogen at around 400 °C and formation of lower-nitrogen content iron nitrides. They are insoluble in water. At high pressure, stability and formation of new nitrogen-rich nitrides (N/Fe ratio equal or greater to one) were suggested and later discovered. These include the FeN, FeN2 and FeN4 solids which become thermodynamically stable from 17.7 GPa, 72 GPa and 106 GPa, respectively. Health hazards When heated to decomposition or exposed to humidity, iron nitride may emit toxic fumes of ammonia. It is considered a moderate explosion hazard. Inhalation of iron nitride dust or powder may cause irritation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steelpan
The steelpan (also known as a pan, steel drum, and sometimes, collectively with other musicians, as a steelband or steel orchestra) is a musical instrument originating in Trinidad and Tobago. Steelpan musicians are called pannists. Description The modern pan is a chromatically pitched percussion instrument made from 55 gallon industrial drums. ''Drum'' refers to the steel drum containers from which the pans are made; the steel drum is more correctly called a ''steel pan'' or ''pan'' as it falls into the idiophone family of instruments, and so is not a drum (which is a membranophone). Some steelpans are made to play in the Pythagorean musical cycle of fourths and fifths. Pan is played using a pair of straight sticks tipped with rubber; the size and type of rubber tip varies according to the class of pan being played. Some musicians use four pansticks, holding two in each hand. This grew out of Trinidad and Tobago's early 20th-century Carnival percussion groups known as ...

Hang (instrument)
The Hang (; plural form: Hanghang) is a type of musical instrument called a handpan, fitting into the idiophone class and based on the Caribbean steelpan instrument. It was created by Felix Rohner and Sabina Schärer in Bern, Switzerland. The name of their company is PANArt Hangbau AG. The Hang is sometimes referred to as a ''hang drum'', but the inventors consider this a misnomer and strongly discourage its use. The instrument is constructed from two half-shells of deep drawn, nitrided steel sheet glued together at the rim leaving the inside hollow and creating the shape of a convex lens. The top ("Ding") side has a center 'note' hammered into it and seven or eight 'tone fields' hammered around the center. The bottom ("Gu") is a plain surface that has a rolled hole in the center with a tuned note that can be created when the rim is struck. The Hang uses some of the same basic physical principles as a steelpan, but modified in such a way as to act as a Helmholtz resonat ...

Helmholtz Resonance
Helmholtz resonance or wind throb is the phenomenon of air resonance in a cavity, such as when one blows across the top of an empty bottle. The name comes from a device created in the 1850s by Hermann von Helmholtz, the ''Helmholtz resonator'', which he used to identify the various frequencies or musical pitches present in music and other complex sounds.Helmholtz, Hermann von (1885), ''On the sensations of tone as a physiological basis for the theory of music'' Second English Edition, translated by Alexander J. Ellis. London: Longma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its freq ...
