Electric piano

An electric piano is a musical instrument that has a piano-style musical keyboard, where sound is produced by means of mechanical hammers striking metal strings or reeds or wire tines, which leads to vibrations which are then converted into electrical signals by pickups (either magnetic, electrostatic, or piezoelectric). The pickups are connected to an instrument amplifier and loudspeaker to reinforce the sound sufficiently for the performer and audience to hear.

History

</div>

The Neo-Bechstein electric piano was built in 1931. The Vierlang-Forster electric piano was introduced in 1937. The RCA Storytone electric piano was built in 1939 in a joint venture between Story & Clark and RCA. The case was designed by John Vassos, the American industrial designer. It debuted at the 1939 World's Fair. In 2020, the Valente Electric Piano was launched commercially; at the time of launch, Valente said that he took inspiration from the Suette Piano, another reed electric piano that was made in Brazil in the 1980s.

Struck tuning-forks

The tuning fork here refers to the struck element having two vibrating parts. In Fender Rhodes instruments, the struck portion of the "fork" is a tine of stiff steel wire. The other part of the fork, parallel and adjacent to the tine, is the tonebar, a sturdy steel bar which acts as a resonator and adds sustain to the sound. The tine is fitted with a spring which can be moved along its length to allow the pitch to be varied for fine-tuning.

Plucked reeds

The Hohner Pianet uses adhesive pads made from an undressed leather surface cushioned by a foam rubber backing. Hohner's later "Pianet T" uses silicone rubber suction pads rather than adhesive pads and replaces the electrostatic system with passive electromagnetic pickups similar to those of the Rhodes.

Other electric keyboard instruments

Hohner's "Clavinet" is essentially an electric clavichord. A rubber pad under each key presses the string onto a metal anvil, causing the "fretted" portion of the string to vibrate. This is detected by a series of pickups, which convert them into an electrical signal.

Digital pianos

Digital pianos that provide an emulated electric piano sound have largely supplanted the actual electro-mechanical instruments in the 2010s, due to the small size, light weight, and versatility of digital instruments, which can produce a huge range of tones besides piano tones (e.g., emulations of Hammond organ sounds, synthesizer sounds, etc.). However, some performers still perform and record with vintage electric pianos. In 2009, Rhodes produced a new line of electro-mechanical pianos, known as the Rhodes Mark 7, followed by an offering from Vintage Vibe.
