Anne Beetem Acker

Technology that allows a person to control a music-related output with commands expressed by brain signals. The output signal can control physical and virtual instruments and composition systems. Therapeutic applications include allowing severely physically disabled persons to participate actively in music-making. A number of methods of detecting and measuring brain activity have been tried; electroencephalography (EEG) has proved to be the most practical. Neural activity generates electric fields that can be detected by EEG electrodes placed on the scalp. The electrodes are placed in an array that allows mapping of neural activity over time. The signals are very weak and must be amplified and broken into frequency bands commonly labeled from low to high as Theta, Delta, Alpha, low Beta, medium Beta, and Gamma....

Line of MIDI-based reproducing player pianos introduced by Yamaha Corporation in 1982 (1986 in North America). The Disklavier system combines an acoustic piano with an electromechanical player-piano system. As in other such systems, fibre-optic sensors register the movement of keys, hammers, and pedals during performance, while the digital controller operates a bank of solenoids installed under the piano’s key bed; one solenoid is positioned under the tail of each key, with additional solenoids connected to the pedal rods. Performance information is stored digitally on CD-ROM, floppy discs (still used for many accompaniments for instructional piano material), or a hard drive. Disklavier systems can be connected to sequencers, tone modules, and computers via MIDI and Ethernet. A built-in speaker system attached to the case under the soundboard is used to play back optional digital piano sound and especially for playback of accompanying orchestral or vocal tracks....

Gnome  

Hugh Davies

Electronic keyboard instrument developed by Ivan Eremeeff in Philadelphia, Pennsylvania, in 1932; it was the smaller and better known of two instruments based on the same principles that Eremeeff built in that year. Rotating electromagnetic tone wheels generated the sounds. The keyboard (three and a half octaves) and the bench on which the player sat formed part of an electrical circuit; when one of the stationary, touch-plate keys was fingered, an electrical contact was made through the performer’s body with the metal top of the bench. In addition to pedals governing volume and tremolo there was also a decay control. The Gnome was designed for home use and could be connected to the amplifier and loudspeaker of a domestic radio set....
