Concept
Clavinet
Summary
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.
Although originally intended for home use, the Clavinet became popular on stage, and could be used to create electric guitar sounds on a keyboard. It is strongly associated with Stevie Wonder, who used the instrument extensively, particularly on his 1972 hit "Superstition", and was regularly featured in rock, funk and reggae music throughout the 1960s and 1970s. Modern digital keyboards can emulate the Clavinet sound, but there is also a grass-roots industry of repairers who continue to maintain the instrument.
The Clavinet is an electromechanical instrument that is usually used in conjunction with a keyboard amplifier. Most models have 60 keys ranging from F1 to E6.
The sound is produced by a harp of 60 tensioned steel strings placed diagonally below the key surface. Each key pivots on a fulcrum point at the rear, with a spring to return it. Beneath each key, a metal holder grips a small rubber pad. Pressing a key forces the pad to fret the string like a hammer on on a guitar. An electro-magnetic pickup turns the string vibration into an electric current. The feel of a clavinet comes from the impact of the pad striking its anvil point against the string. This makes the keyboard weighted which allows a different volume for each note like a piano and clavichord, along with aftertouch as the string is stretched.
The end of each string farthest from the pick-ups passes through a weave of yarn, which damps the vibrating string after a key is released. Each string is tuned by a machine-head positioned along the front of the harp. This harp mechanism is different from the other Hohner keyboard instruments, the Cembalet and Pianet, which have pads plucking metal reeds.
