The Hammond organ is an electric organ invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Multiple models have been produced, most of which use sliding drawbars to vary sounds. Until 1975, Hammond organs generated sound by creating an electric current from rotating a metal tonewheel near an electromagnetic pickup, and then strengthening the signal with an amplifier to drive a speaker cabinet. The organ is commonly used with the Leslie speaker.
The harmonica, also known as a French harp, mouth harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock. The many types of harmonica include diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth to direct air into or out of one holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. The most common is the diatonic Richter-tuned with ten air passages and twenty reeds, often called the blues harp. A harmonica reed is a flat, elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound.
The Rhodes piano is an electric piano invented by Harold Rhodes, which became popular in the 1970s. Like a conventional piano, the Rhodes generates sound with keys and hammers, but instead of strings, the hammers strike thin metal tines, which vibrate next to an electromagnetic pickup. The signal is then sent through a cable to an external keyboard amplifier and speaker.
Vox is a British musical equipment manufacturer founded in 1957 by Thomas Walter Jennings in Dartford, Kent, England. The company is most famous for making the Vox AC30 guitar amplifier, used by The Beatles, The Rolling Stones, The Kinks, The Yardbirds, Queen, Dire Straits, U2, and Radiohead; the Vox Continental electric organ, the Vox wah-wah pedal used by Jimi Hendrix, and a series of innovative electric guitars and bass guitars. Since 1992, Vox has been owned by the Japanese electronics firm Korg.
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. The pickups are connected to an instrument amplifier and loudspeaker to reinforce the sound sufficiently for the performer and audience to hear. Unlike a synthesizer, the electric piano is not an electronic instrument. Instead, it is an electro-mechanical instrument. Some early electric pianos used lengths of wire to produce the tone, like a traditional piano. Smaller electric pianos used short slivers of steel to produce the tone. The earliest electric pianos were invented in the late 1920s; the 1929 Neo-Bechstein electric grand piano was among the first. Probably the earliest stringless model was Lloyd Loar's Vivi-Tone Clavier. A few other noteworthy producers of electric pianos include Baldwin Piano and Organ Company, and the Wurlitzer Company.
The Clavinet is an electrically amplified clavichord invented by Ernst Zacharias and manufactured by the Hohner company of Trossingen, West Germany, from 1964 to 1982. The instrument produces sounds with rubber pads, each matching one of the keys and responding to a keystroke by striking a given point on a tensioned string, and was designed to resemble the Renaissance-era clavichord.
Farfisa is a manufacturer of electronics based in Osimo, Italy, founded in 1946. The company manufactured a series of compact electronic organs in the 1960s and 1970s, including the Compact, FAST, Professional and VIP ranges, and later, a series of other keyboard instruments. They were used by a number of popular musicians including Sam the Sham, Country Joe and the Fish, Pink Floyd, Sly Stone, Blondie, and the B-52s.
Hohner Musikinstrumente GmbH & Co. KG is a German manufacturer of musical instruments, founded in 1857 by Matthias Hohner (1833–1902). The roots of the Hohner firm are in Trossingen, Baden-Württemberg. Since its foundation, and though known for its harmonicas, Hohner has manufactured a wide range of instruments, such as kazoos, accordions, recorder flutes, melodicas, banjos, electric, acoustic, resonator and classical guitars, basses, mandolins and ukuleles.
A stage piano is an electronic musical instrument designed for use in live performances on stage or in a studio, as well as for music recording in Jazz and popular music. While stage pianos share some of the same features as digital pianos designed for home use and synthesizers, they have a number of features which set them apart. Stage pianos usually provide a smaller number of sounds, with these being of higher quality than the ones found on regular digital pianos and home synthesizers.
Rocky Mount Instruments (RMI) was a subsidiary of the Allen Organ Company, based in Rocky Mount, North Carolina, active from 1966 to 1982. The company was formed to produce portable musical instruments, and manufactured several electronic pianos, harpsichords, and organs that used oscillators to create sound, instead of mechanical components like an electric piano.
The Claviola is a musical instrument that was designed in the 1960s by Hohner technician and designer Ernst Zacharias. The instrument was produced for a few months in the late 1990s before being discontinued.
The Wurlitzer electronic piano is an electric piano manufactured and marketed by Wurlitzer from 1954 to 1983. Sound is generated by striking a metal reed with a hammer, which induces an electric current in a pickup. It is conceptually similar to the Rhodes piano, though the sound is different.
The Fender Contempo Organ is a combo organ made by Fender during the late 1960s. It was designed to compete with similar instruments such as the Vox Continental and Farfisa Compact, and had additional stops, features and controllers not found on the other models. However, it was only in production for a few years as it struggled to compete with the more popular Hammond organ and Rhodes piano.
The Vox Continental is a transistorised combo organ that was manufactured between 1962 and 1971 by the British musical equipment manufacturer Vox. It was designed for touring musicians and as an alternative to the heavy Hammond organ. It supports drawbars in a similar manner to the Hammond, and has distinctive reverse-coloured keys. The sound is generated by a series of oscillators, using a frequency divider to span multiple octaves.
The Gibson G-101 is a transistorised combo organ, manufactured in the late 1960s by the Lowrey Organ Company for Gibson.
The Cembalet is a type of electro-mechanical piano built by the Hohner company of Trossingen, West Germany from the late-1950s to the late 1960s, and designed by Ernst Zacharias. It was a reed-based electric piano intended for home use, and the first keyboard produced by Hohner as a piano-like instrument rather than an instrument having the sustained note of an organ. It was adopted by popular musicians for recording and performance in the early 1960s because it was portability and easy to amplify electronically.
Ernst Zacharias was a German musician and engineer. In the 1950s and 1960s, he invented various electro-mechanical musical instruments for the German musical instrument manufacturer Hohner, including the Cembalet, the Clavinet, the Guitaret, and the Pianet. The Claviola, a modernisation of the sheng and the Harmonetta, a mouth-blown concertina-keyboarded instrument, was also invented by Zacharias. He additionally invented the Electra-Melodica, the first commercially produced wind synthesizer. DEPATIS lists 90 patents by Ernst Zacharias for Hohner, including plastic recorders and watch and clock mechanisms.
The Guitaret is an electric lamellophone made by Hohner and invented by Ernst Zacharias, in 1963. Zacharias also invented similar instruments like the Pianet, Cembalet and the Clavinet.
A digital accordion is an electronic musical instrument that uses the control features of a traditional accordion to trigger a digital sound module that produces synthesized or digitally sampled accordion sounds or, in most instruments, a range of non-accordion sounds, such as orchestral instruments, pipe organ, piano, guitar, and so on. Digital accordions typically encode and transmit key presses and other input as Musical Instrument Digital Interface (MIDI) messages. Most digital accordions need to be plugged into a keyboard amplifier or PA system to hear their sounds.
The Yamaha CP-70 is an electric piano manufactured by Yamaha Corporation between 1976 and 1985. The instrument was based on earlier electric piano technology, but took advantage of improved pickups along with the company's longstanding experience in manufacturing acoustic pianos.
