Knowra Electric organ Electric organ An electric organ is a keyboard instrument that generates sound electronically and sends it through amplification and loudspeakers. It commonly uses multiple manuals, pedal keyboards, and controls that shape its timbre.
Tonewheel organ : An electronic organ that generates tones with rotating toothed wheels and electromagnetic pickups. Its rotating tonewheels provide the characteristic continuous tones of classic electric organs.
Manual (keyboard) : A keyboard played by the hands, especially one of the stacked keyboards on an organ. Multiple manuals let organists assign different sounds or parts to each hand.
Laurens Hammond : An American engineer and inventor who developed the Hammond organ and founded the Hammond Clock Company. His 1930s instrument made electric organs commercially prominent.
Gospel music : A Christian music tradition shaped by spirituals, hymns, and Black American musical practices. Organists use sustained chords and expressive runs to support gospel singing.
Pipe organ : A keyboard instrument that produces sound by sending air through pipes. It creates tones acoustically, unlike an electric organ’s electronic sound generation.
Electronic oscillator : An electronic circuit that produces a repeating signal at a chosen frequency. Oscillators generate pitches in many organs that do not use tonewheels.
Pedal keyboard : A foot-operated keyboard used to play bass notes on an organ. It supplies an independent bass part beneath the manual keyboards.
Hammond Organ Company : An American manufacturer best known for Hammond electric organs and related instruments. The company established a major design lineage for electric organs.
Jazz organ trio : A jazz ensemble commonly featuring organ, guitar, and drums. The organ combines bass, harmony, and melody in a compact ensemble.
Synthesizer : An electronic instrument that creates and shapes sound through oscillators, samples, or digital algorithms. Synthesizers offer broader sound design, while organs center on sustained keyboard tones and registrations.
