Electrophone

As Elektrophon one designated according to the Hornbostel -Sachs system ostensibly the group of musical instruments, must use the custom to play the sound event headphones or the respective proportions of space corresponding audio amplifier with subsequent speakers. The actual technology used the tone and playing style is very diverse.

In extended and associated sense could belong to the electric -speakers and MIDI devices that do not have their own sound input device or just for storing a corresponding MIDI (sequencer ) are used. Here, since the limits for computer technology are fluid, precise categorization is not possible and also considers the actual user as not necessary.

You can do by way of playing after tone distinction or discrimination.

History

In the German literature, especially in works of the Moravian preacher Prokop Divis has the distinction of having created as early as 1730 with the development of the Denis d'or, the first Elektrophon. However, this is based on the phrase " electric wing mutation " in the Reallexicon Musical Instruments by Curt Sachs in 1913, which was misinterpreted. The piano was a mutation electrically was only an electrical shock, which could be administered to the game ends.

Static electricity to create sound on the other hand took 1759 the French Jesuit Jean -Baptiste Delaborde with the Clavicin électrique.

The tech-savvy Berlin lawyer Richard Eisenmann, a student of Helmholtz, invented in 1900, a device with which you could with a piano other instruments, such as an organ or a stringed instrument imitate. It was also possible with this invention, to let sounds rise and fall. To influence the vibrations of the strings and to vary the timbre, Eisenmann used a device that was very advanced for its time. In contemporary reports, it is described as follows:

" For the operation of the piano part of a Acckumulatorenbatterie of ten cells. On each string is a horseshoe magnet, the one end of the wire is set to the all other electromagnets to a common metal bar, which is connected by a circuit breaker of special construction with the battery. The switching on and off of the circuit breaker is accomplished by a pedal, by the movements of the current can be varied, whereby the above-mentioned modulation are caused. "
