Hydraulophone
A hydraulophone is a Tonality, tonal acoustic musical instrument played by direct physical contact with water (sometimes other fluids) where sound is generated or affected hydraulics, hydraulically."Fluid Melodies: The hydraulophones of Professor Steve Mann" In WaterShapes, Volume 10, Number 2, Pp 36–44, New York, NY, USA. Volume 10, No 2, 2008 February Oct 27, 2006 The hydraulophone was described and named by Steve Mann (inventor), Steve Mann in 2005, and patented in 2011. Typically, sound is produced by the same hydraulic fluid in contact with the player's fingers. It has been used as a sensory exploration device for low-vision individuals. Types and basic operation The term may be applied based on the interface used to play the instrument, in which a player blocks the flow of water through a particular hole in order to sound a particular note, or based on a hydraulic sound production mechanism. Hydraulophones use water-flow sound-producing mechanisms. They have a user i ...

Hart House Symphonic Band
Hart House Symphonic Band (HHSB) is a wind orchestra, with woodwind, brass, and percussion sections, based at Hart House at the University of Toronto. HHSB is historically noteworthy as the first symphonic band to have instruments in which the initial sound-producing mechanisms of the instruments cover all three states of matter: solid, liquid, and gas. While other orchestras have three categories of instruments (strings, percussion, and wind), two of these categories (strings and percussion) use matter in its solid state, and one category (wind instruments) uses matter in its gaseous state. HHSB is, in some sense, the first large symphonic orchestra to use hydraulophone A hydraulophone is a Tonality, tonal acoustic musical instrument played by direct physical contact with water (sometimes other fluids) where sound is generated or affected hydraulics, hydraulically."Fluid Melodies: The hydraulophones of Professo ...s, musical instruments that produce the initial sound b ...

Glass Harmonica
The glass harmonica, also known as the glass armonica, glass harmonium, bowl organ, hydrocrystalophone, or simply the armonica or harmonica (derived from , ''harmonia'', the Greek language, Greek word for harmony), is a type of musical instrument that uses a series of glass bowl (vessel), bowls or goblets graduated in size to produce musical pitch (music), tones by means of friction (instruments of this type are known as friction idiophones). It was invented in 1761 by Benjamin Franklin. Nomenclature The name "glass harmonica" (also "glass armonica", "glassharmonica"; ''harmonica de verre'', ''harmonica de Franklin'', ''armonica de verre'', or just ''harmonica'' in French; ''Glasharmonika'' in German; ''harmonica'' in Dutch) refers today to any instrument played by rubbing glass or crystal goblets or bowls. The alternative instrument consisting of a set of wine glasses (usually tuned with water) is generally known in English as "musical glasses" or the "glass harp". When Be ...

Fipple
The term fipple specifies a variety of end-blown flute that includes the flageolet, recorder, and tin whistle. The Hornbostel–Sachs system for classifying musical instruments places this group under the heading "Flutes with duct or duct flutes." The label "fipple flute" is frequently applied to members of the subgroup but there is no general agreement about the structural detail of the sound-producing mechanism that constitutes the fipple itself. Nomenclature The accompanying illustration of the mouthpiece of a recorder shows a wooden block (A) with a channel carved into the body of the instrument (B), together forming a duct that directs a ribbon of air across an opening toward a sharp edge (C). The edge splits the air in a manner that alternately directs it into and outside of the tube, setting the contained column of air into periodic vibration. This flow-controlled "air reed" is a definitive characteristic of all flutes, which therefore all have an edge or equivalent air ...

Kinematics And Musical Instruments
In physics, kinematics studies the geometrical aspects of motion of physical objects independent of forces that set them in motion. Constrained motion such as linked machine parts are also described as kinematics. Kinematics is concerned with systems of specification of objects' positions and velocities and mathematical transformations between such systems. These systems may be rectangular like cartesian, Curvilinear coordinates like polar coordinates or other systems. The object trajectories may be specified with respect to other objects which may themselve be in motion relative to a standard reference. Rotating systems may also be used. Numerous practical problems in kinematics involve constraints, such as mechanical linkages, ropes, or rolling disks. Overview Kinematics is a subfield of physics and mathematics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces ...

Woodwind Instrument
Woodwind instruments are a family of musical instruments within the greater category of wind instruments. Common examples include flute, clarinet, oboe, bassoon, and saxophone. There are two main types of woodwind instruments: flutes and reed instruments (otherwise called reed pipes). The main distinction between these instruments and other wind instruments is the way in which they produce sound. All woodwinds produce sound by splitting the air blown into them on a sharp edge, such as a reed or a fipple. Despite the name, a woodwind may be made of any material, not just wood. Common examples of other materials include brass, silver, cane, and other metals such as gold and platinum. The saxophone, for example, though made of brass, is considered a woodwind because it requires a reed to produce sound. Occasionally, woodwinds are made of earthen materials, especially ocarinas. Flutes Flutes produce sound by directing a focused stream of air across the edge of a hole i ...

Pipe Organ
The pipe organ is a musical instrument that produces sound by driving pressurised air (called ''wind'') through the organ pipes selected from a Musical keyboard, keyboard. Because each pipe produces a single tone and pitch, the pipes are provided in sets called ''ranks'', each of which has a common timbre, volume, and construction throughout the keyboard Compass (music), compass. Most organs have many ranks of pipes of differing pitch, timbre, and volume that the player can employ singly or in combination through the use of controls called Organ stop, stops. A pipe organ has one or more keyboards (called ''Manual (music), manuals'') played by the hands, and most have a Pedal keyboard, pedal clavier played by the feet; each keyboard controls its own division (group of stops). The keyboard(s), pedalboard, and stops are housed in the organ's Organ console, ''console''. The organ's continuous supply of wind allows it to sustain notes for as long as the corresponding keys are pressed, ...

Polyphonic
Polyphony ( ) is a type of musical texture consisting of two or more simultaneous lines of independent melody, as opposed to a musical texture with just one voice ( monophony) or a texture with one dominant melodic voice accompanied by chords ( homophony). Within the context of the Western musical tradition, the term ''polyphony'' is usually used to refer to music of the late Middle Ages and Renaissance. Baroque forms such as fugue, which might be called polyphonic, are usually described instead as contrapuntal. Also, as opposed to the ''species'' terminology of counterpoint, polyphony was generally either "pitch-against-pitch" / "point-against-point" or "sustained-pitch" in one part with melismas of varying lengths in another. In all cases the conception was probably what Margaret Bent (1999) calls "dyadic counterpoint", with each part being written generally against one other part, with all parts modified if needed in the end. This point-against-point conception is oppose ...

Diatonic
Diatonic and chromatic are terms in music theory that are used to characterize scales. The terms are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900. These terms may mean different things in different contexts. Very often, ''diatonic'' refers to musical elements derived from the modes and transpositions of the "white note scale" C–D–E–F–G–A–B. In some usages it includes all forms of heptatonic scale that are in common use in Western music (the major, and all forms of the minor). ''Chromatic'' most often refers to structures derived from the chromatic scale in 12-tone equal temperament, which consists of all semitones. Historically, however, it had other senses, referring in Ancient Greek music theory to a particular tuning of the tetrachord, and to a rhythmic notati ...
