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.
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones. The organs have usually two or three, up to five, manuals for playing with the hands and a pedalboard for playing with the feet. With the use of registers, several groups of pipes can be connected to one manual.
The Leslie speaker is a combined amplifier and loudspeaker that projects the signal from an electric or electronic instrument and modifies the sound by rotating a baffle chamber ("drum") in front of the loudspeakers. A similar effect is provided by a rotating system of horns in front of the treble driver. It is most commonly associated with the Hammond organ, though it was later used for the electric guitar and other instruments. A typical Leslie speaker contains an amplifier, a treble horn and a bass speaker—though specific components depend upon the model. A musician controls the Leslie speaker by either an external switch or pedal that alternates between a slow and fast speed setting, known as "chorale" and "tremolo".
James Oscar Smith was an American jazz musician who helped popularize the Hammond B-3 organ, creating a link between jazz and 1960s soul music.
An electric organ, also known as electronic organ, is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally designed to imitate their sound, or orchestral sounds, it has since developed into several types of instruments:
The word "manual" is used instead of the word "keyboard" when referring to any hand-operated keyboard on a keyboard instrument that has a pedalboard, such as an organ; or when referring to one of the keyboards on an instrument that has more than one hand-operated keyboard, such as a two- or three-manual harpsichord.
Joey DeFrancesco was an American jazz organist, trumpeter, saxophonist, and occasional singer. He released more than 30 albums under his own name, and recorded extensively as a sideman with such leading jazz performers as trumpeter Miles Davis, saxophonist Houston Person, and guitarist John McLaughlin.
A clonewheel organ is an electronic musical instrument that emulates the sound of the electromechanical tonewheel-based organs formerly manufactured by Hammond from the 1930s to the 1970s. Clonewheel organs generate sounds using solid-state circuitry or computer chips, rather than with heavy mechanical tonewheels, making clonewheel organs much lighter-weight and smaller than vintage Hammonds, and easier to transport to live performances and recording sessions.
The Nord Electro is a series of electronic keyboards, developed in Sweden by Clavia, that digitally emulate electro-mechanical keyboards, such as electric pianos and electronic organs, while designed to be highly portable.
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.
An organ trio is a form of jazz ensemble consisting of three musicians; a Hammond organ player, a drummer, and either a jazz guitarist or a saxophone player. In some cases the saxophonist will join a trio which consists of an organist, guitarist, and drummer, making it a quartet. Organ trios were a popular type of jazz ensemble for club and bar settings in the 1950s and 1960s, performing a blues-based style of jazz that incorporated elements of R&B. The organ trio format was characterized by long improvised solos and an exploration of different musical "moods".
The Roland VK-7 is an electronic keyboard introduced in 1997 which simulates the sound of an electromechanical Hammond organ. Like other electronic musical instruments that emulate the sound of the electromechanical tonewheel-based organs formerly manufactured by Hammond, the VK-7 is referred to as a clonewheel organ. Currently it is replaced by the VK-8 and the VK-88.
Tokyo Live is a live jazz album released by The Free Spirits on Verve in 1994. Despite the group credit on the sleeve, the record is generally considered to be a McLaughlin solo album.
"Papa" John DeFrancesco was an American jazz organist and vocalist, and father of Joey DeFrancesco and Johnny DeFrancesco. DeFrancesco died on June 25, 2024, at the age of 83.
Jerry Weldon is a tenor saxophonist, noted for his involvement in various groups such as Lionel Hampton Orchestra and Harry Connick, Jr.'s big band. He is seen as a "veteran" of the New York jazz scene.
Never Can Say Goodbye: The Music of Michael Jackson is an album by jazz organist Joey DeFrancesco, a tribute to deceased entertainer Michael Jackson. The album was released in 2010 on HighNote Records and was produced by DeFrancesco and Glenn Ferracone. It was nominated for the 2011 Grammy Award for Best Contemporary Jazz Album.
The Korg CX-3 is an electronic clonewheel organ with drawbars that simulates the sound of an electromechanical Hammond organ and the Leslie speaker, a rotating speaker effect unit. The CX-3 was first introduced in 1979.
