Accordion Reed Ranks And Switches
A reed rank inside an accordion is a single full set of the reeds that are the means to achieve the instrument's sound range. These reed ranks are located in the reed chamber. Most accordions to this date typically have between two and four reed ranks on the treble side and between three and five reed ranks on the bass side. These can usually be selected individually or combined in various ways to provide a range of different timbres, by use of register switches arranged by register from high to low. More of the top-line expensive accordions may contain five or six reed blocks on the treble side for different tunings, typically found in accordions that stress musette sounds. How many reeds an accordion has is specified by the number of treble ranks and bass ranks. For example, a 4/5 accordion has four reeds on the treble side and five on the bass side. A 3/4 accordion has three reeds on the treble sides and four on the bass side. Reed ranks are classified by either organ 'foo ...

Accordion Right Hand Timbre Switches
Accordions (from 19th-century German language, German ''Akkordeon'', from ''Akkord''—"musical chord, concord of sounds") are a family of box-shaped musical instruments of the bellows-driven free reed aerophone, free-reed aerophone type (producing sound as air flows past a Reed (mouthpiece), reed in a frame), colloquially referred to as a squeezebox. A person who plays the accordion is called an accordionist. The concertina , harmoneon and Bandoneon, bandoneón are related. The harmonium and American reed organ are in the same family, but are typically larger than an accordion and sit on a surface or the floor. The accordion is played by compressing or expanding the bellows while pressing buttons or Musical keyboard, keys, causing ''pallets'' to open, which allow air to flow across strips of brass or steel, called ''reed (instrument), reeds''. These vibrate to produce sound inside the body. Valves on opposing reeds of each note are used to make the instrument's reeds sound lo ...

Perfect Fifth
In music theory, a perfect fifth is the Interval (music), musical interval corresponding to a pair of pitch (music), pitches with a frequency ratio of 3:2, or very nearly so. In classical music from Western culture, a fifth is the interval from the first to the last of five consecutive Musical note, notes in a diatonic scale. The perfect fifth (often abbreviated P5) spans seven semitones, while the Tritone, diminished fifth spans six and the augmented fifth spans eight semitones. For example, the interval from C to G is a perfect fifth, as the note G lies seven semitones above C. The perfect fifth may be derived from the Harmonic series (music), harmonic series as the interval between the second and third harmonics. In a diatonic scale, the dominant (music), dominant note is a perfect fifth above the tonic (music), tonic note. The perfect fifth is more consonance and dissonance, consonant, or stable, than any other interval except the unison and the octave. It occurs above the ...

Organ Stop
An organ stop is a component of a pipe organ that admits pressurized air (known as ''wind'') to a set of organ pipes. Its name comes from the fact that stops can be used selectively by the organist; each can be "on" (admitting the passage of air to certain pipes), or "off" (''stopping'' the passage of air to certain pipes). The term can also refer to the control that operates this mechanism, commonly called a stop tab, stop knob, or drawknob. On electric or electronic organs that imitate a pipe organ, the same terms are often used, with the exception of the Hammond organ and clonewheel organs, which use the term "Hammond organ#Drawbars, drawbar". The term is also sometimes used as a synonym for register, referring to rank(s) of pipes controlled by a single stop. Registration (organ), Registration is the art of combining stops to produce a certain sound. The phrase "wikt:pull out all the stops, pull out all the stops,” while once only meant to engaging all voices on the organ, ...

Combination Action
Registration is the technique of choosing and combining the stops of a pipe organ in order to produce a particular sound. ''Registration'' can also refer to a particular combination of stops, which may be recalled through combination action. The registration chosen for a particular piece will be determined by a number of factors, including the composer's indications (if any are given), the time and place in which the piece was composed, the organ the piece is played upon, and the acoustic environment within which the organ resides. Pitch and timbre The pitch produced by a pipe is a function of its length. An organ stop may be tuned to sound (or "speak at") the pitch normally associated with the key that is pressed (the "unison pitch"), or it may speak at a fixed interval above or below this pitch (an "octave pitch"). Some stops are tuned to notes "in-between" the octaves and are called "Mutations" (see below). The pitch of a rank of pipes is denoted by a number on the stop knob ...

University Of Copenhagen
The University of Copenhagen ( da, Københavns Universitet, KU) is a prestigious public university, public research university in Copenhagen, Copenhagen, Denmark. Founded in 1479, the University of Copenhagen is the second-oldest university in Scandinavia after Uppsala University, and ranks as one of the top universities in the Nordic countries, Europe and the world. Its establishment sanctioned by Pope Sixtus IV, the University of Copenhagen was founded by Christian I of Denmark as a Catholic teaching institution with a predominantly Theology, theological focus. In 1537, it was re-established by King Christian III as part of the Lutheran Reformation. Up until the 18th century, the university was primarily concerned with educating clergymen. Through various reforms in the 18th and 19th century, the University of Copenhagen was transformed into a modern, Secularism, secular university, with science and the humanities replacing theology as the main subjects studied and taught.

Tremolo
In music, ''tremolo'' (), or ''tremolando'' (), is a trembling effect. There are two types of tremolo. The first is a rapid reiteration: * Of a single Musical note, note, particularly used on String instrument#Bowing, bowed string instruments, by rapidly moving the bow back and forth; plucked strings such as on a harp, where it is called ''wikt:bisbigliando, bisbigliando'' () or "whispering". Tremolo picking, on traditionally plucked string instruments including guitar and mandolin, is the rapid articulation of single notes or a group of notes with a plectrum (pick) or with fingers. Tremolo playing sustains notes that would otherwise rapidly decay (fade to silence). * Between two notes or chords in alternation, an imitation (not to be confused with a trill (music), trill) of the preceding that is more common on keyboard instruments. Mallet instruments such as the marimba are capable of either method. * A drum roll, roll on any percussion instrument, whether tuned or untuned. ...

Beat (acoustics)
In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, ''perceived'' as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized. Tuning two tones to a unison will present a peculiar effect: when the two tones are close in pitch but not identical, the difference in frequency generates the beating. The volume varies like in a tremolo as the sounds alternately interfere constructively and destructively. As the two tones gradually approach unison, the beating slows down and may become so slow as to be imperceptible. As the two tones get further apart, their beat frequency starts to approach the range of human pitch perception, the beating starts to sound like a note, and a combination tone is produced. This combination tone can also be referred to as a missing fundamental, as the beat frequency of any two tones is equivalen ...
