Dynamic Tonality
Dynamic tonality is a paradigm for tuning and timbre which generalizes the special relationship between just intonation and the harmonic series to apply to a wider set of pseudo-just tunings and related pseudo-harmonic timbres.Duffin, R.W., 2006''How Equal Temperament Ruined Harmony (and Why You Should Care)''/ref> This misalignment, in any tuning that is not fully Just (and hence infinitely complex), is the defining characteristic of the Static Timbre Paradigm. Instruments Many of the pseudo-just temperaments proposed during this "temperament battle" were rank-2 (two-dimensional)—such as quarter-comma meantone—that provided more than 12 notes per octave. However, the standard piano-like keyboard is only rank-1 (one-dimensional), affording at most 12 notes per octave. Piano-like keyboards affording more than 12 notes per octave were developed by Vicentino, Colonna, Mersenne, Huygens, and Newton, but were deemed cumbersome and difficult to learn.

Paradigm
In science and philosophy, a paradigm () is a distinct set of concepts or thought patterns, including theories, research methods, postulates, and standards for what constitute legitimate contributions to a field. Etymology ''Paradigm'' comes from Greek παράδειγμα (''paradeigma''), "pattern, example, sample" from the verb παραδείκνυμι (''paradeiknumi''), "exhibit, represent, expose" and that from παρά (''para''), "beside, beyond" and δείκνυμι (''deiknumi''), "to show, to point out". In classical (Greek-based) rhetoric, a paradeigma aims to provide an audience with an illustration of a similar occurrence. This illustration is not meant to take the audience to a conclusion, however it is used to help guide them get there. One way of how a ''paradeigma'' is meant to guide an audience would be exemplified by the role of a personal accountant. It is not the job of a personal accountant to tell a client exactly what (and what not) to spend money ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map (mathematics)
In mathematics, a map or mapping is a function in its general sense. These terms may have originated as from the process of making a geographical map: ''mapping'' the Earth surface to a sheet of paper. The term ''map'' may be used to distinguish some special types of functions, such as homomorphisms. For example, a linear map is a homomorphism of vector spaces, while the term linear function may have this meaning or it may mean a linear polynomial. In category theory, a map may refer to a morphism. The term ''transformation'' can be used interchangeably, but '' transformation'' often refers to a function from a set to itself. There are also a few less common uses in logic and graph theory. Maps as functions In many branches of mathematics, the term ''map'' is used to mean a function, sometimes with a specific property of particular importance to that branch. For instance, a "map" is a " continuous function" in topology, a " linear transformation" in linear algebra, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bayan (accordion)
The bayan ( rus, бая́н, p=bɐˈjan) is a type of chromatic button accordion developed in the Russian Empire in the early 20th century and named after the 11th-century bard Boyan. Characteristics The bayan differs from western chromatic button accordions in some details of construction: * Reeds are broader and rectangular (rather than trapezoidal). * Reeds are often attached in large groups to a common plate (rather than in pairs); the plates are screwed to the reed block (rather than attached with wax). * The melody-side keyboard is attached near the middle of the body (rather than at the rear). * Reeds are generally not tuned with tremolo. * Register switches may be operated with the chin on some larger models (also possible with some larger European button accordions). * The diminished chord row is shifted, so that the diminished G chord is where one would expect the diminished C chord in the Stradella bass system. * Converter switches that go from standard prese ...

Bandoneon
The bandoneon (or bandonion, es, bandoneón) is a type of concertina particularly popular in Argentina and Uruguay. It is a typical instrument in most tango ensembles. As with other members of the concertina family, the bandoneon is held between the hands, and by pulling and pushing actions force air through bellows and then routing air through particular reeds as by pressing the instrument's buttons. Bandoneons have a different sound from accordions, because bandoneons do not usually have the register switches that are common on accordions. Nevertheless, the tone of the bandoneon can be changed a great deal using varied bellows pressure and overblowing, thus creating potential for expressive playing and diverse timbres. History The Bandonion, so named by the German instrument dealer Heinrich Band (1821–1860), was originally intended as an instrument for religious and popular music of the day, in contrast to its predecessor, German concertina (), which had predomin ...
