Dodeka Keyboard
The Dodeka Keyboard design is an isomorphic keyboard invented and designed by Jacques-Daniel Rochat. It is similar to a piano keyboard but with only a single row of keys containing each chromatic note. The keys corresponding to C, E and A flat are highlighted to provide visual landmarks. The creators aimed to create a rational and chromatic approach to music and performance. As an isomorphic keyboard, any musical sequence or interval has the same shape in each of the 12 keys. Music notation The Dodeka design was developed together with the Dodeka Music Notation.{{Cite book, url=https://www.worldcat.org/oclc/1078658738, title=Dodeka : la révolution musicale, last=Rochat, first=Jacques-Daniel, date=2018, publisher=Crea 7, isbn=9782970127505, location=Chexbres, oclc=1078658738 It consists of a four-line chromatic staff, and represents rhythms only using the visual length of a bar on the staff, reminiscent of the appearance of "piano roll" in digital audio workstations.

Isomorphic Keyboard
An isomorphic keyboard is a musical input device consisting of a two-dimensional grid of note-controlling elements (such as buttons or keys) on which any given sequence and/or combination of musical intervals has the "same shape" on the keyboard wherever it occurs – within a key, across keys, across octaves, and across tunings. Examples Helmholtz's 1863 book ''On the Sensations of Tone'' gave several possible layouts. Practical isomorphic keyboards were developed by Bosanquet (1875), Janko (1882), Wicki (1896), Fokker (1951), Erv Wilson (1975–present), William Wesley (2001), and Antonio Fernández (2009). Accordions have been built since the 19th century using various isomorphic keyboards, typically with dimensions of semitones and tones. The keyboards of Bosanquet and Erv Wilson are also known as generalized keyboards. The keyboard of Antonio Fernández is also known as Transclado. The Ragzpole is a recently developed cylindrical MIDI controller having dimensions in fift ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dodeka Music Notation
The Dodeka Music Notation is an alternative music notation or musical notation system invented and designed in 1980s by inventor and musician Jacques-Daniel Rochat in an attempt to improve upon traditional music notation. Staff and pitch Unlike conventional musical notation, the Dodeka music notation system uses a chromatic scale of 12 pitches and follows an equal pitch intervals configuration, with 4 lines per octave. In this configuration, the 12 notes of an octave appear in four positions vis-à-vis the staff lines, that is, either on, between, above and below the lines. Each pitch has its own unique place on the staff. And while conventional music notation may alter notes using accidental signs or key signatures, notes in the Dodeka notation appear as they are. There are no more key signatures or accidental signs in this musical system. Note duration The Dodeka notation system represents note duration in a visual manner. Note lengths are represented through the notes g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musical Notation
Music notation or musical notation is any system used to visually represent aurally perceived music played with instruments or sung by the human voice through the use of written, printed, or otherwise-produced symbols, including notation for durations of absence of sound such as rests. The types and methods of notation have varied between cultures and throughout history, and much information about ancient music notation is fragmentary. Even in the same time period, such as in the 2010s, different styles of music and different cultures use different music notation methods; for example, for professional classical music performers, sheet music using staves and noteheads is the most common way of notating music, but for professional country music session musicians, the Nashville Number System is the main method. The symbols used include ancient symbols and modern symbols made upon any media such as symbols cut into stone, made in clay tablets, made using a pen on papyrus or ...

Digital Audio Workstations
A digital audio workstation (DAW) is an electronic device or application software used for Sound recording and reproduction, recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece. DAWs are used for producing and recording music, songs, human speech, speech, Radio broadcasting, radio, television, soundtracks, podcasts, sound effects and nearly any other situation where complex recorded audio is needed. Hardware Early attempts at digital audio workstations in the 1970s and 1980s faced limitations such as the high price of storage, and the vastly slower processing and disk speeds of the time. In 1978, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jankó Keyboard
The Jankó keyboard is a musical keyboard layout for a piano designed by Paul von Jankó, a Hungarian pianist and engineer, in 1882. It was designed to overcome two limitations on the traditional piano keyboard: the large-scale geometry of the keys (stretching beyond a ninth, or even an octave, can be difficult or impossible for pianists with small hands), and the fact that each scale has to be fingered differently. Instead of a single row, the Jankó keyboard has an array of keys consisting of two interleaved manuals with three touch-points for every key lever, making six rows of keys. Each vertical column of three keys is a semitone away from the neighboring ones, which are in the alternate rows. Thus within each row the interval from one note to the next is a whole step. This key layout results in each chord and scale having the same shape on the keyboard with the same fingerings regardless of key, so there is no change in geometry when transposing music. Furthermore, the us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric And Electronic Keyboard Instruments
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...
