The electric chord organ is a type of home organ that was first introduced in 1950. It has a single short keyboard and a set of chord buttons, allowing the musician to play a melody or lead with one hand and accompanying chords with the other. The left-hand panel has buttons to play harmony, and 96 separate chord buttons provide various chords for all 12 musical keys. The right-hand keyboard can play both chords and single notes. This type of organ is designed to be easy to learn and play, with automatic chord generation features and simplified controls. Playing the electric chord organ involves using the left hand to operate the chord buttons while the right hand plays the keyboard, similar to the accordion. The expression pedals control the volume and crescendo, and the stops, indicated by white buttons or tabs above the keyboard, determine the sound and color.

What You'll Learn
The basics of the electric chord organ
The electric chord organ is a type of home organ that is designed to be easy to play, requiring little knowledge of piano or organ playing techniques. It is a compact and relatively inexpensive instrument that was first introduced in 1950. The chord organ has a single manual that is typically an octave shorter than a spinet organ, and it lacks a pedalboard. The left hand operates an array of chord buttons, while the right hand plays a 37-note keyboard.
To play the electric chord organ, you can use your left hand to press the chord buttons to play harmony, and your right hand to play the keyboard to play chords and single notes. The chord buttons typically provide Major, Minor, 7th, Diminished, Augmented, Major 6th, Minor 7th, and 9th chords for all 12 musical keys. Additionally, there are two bass pedals that can be played with the left foot to sound the "root" and "fifth" of each chord. Rhythm can be added by striking a bar with the palm or thumb of the left hand.
The organ is unique in that it sustains indefinitely, while other instruments in this family, such as the clavinet, decay over time. The electric piano, another related instrument, has a thicker tonality than an acoustic piano, so you may need to adjust your playing style by using smaller chord voicings and fewer notes. For example, it is recommended to avoid playing octaves with your left hand on an electric piano.
The electric chord organ has internal speakers and can be controlled using expression pedals near your feet, similar to a piano. These pedals control the volume and crescendo. The stops, which are the white buttons or tabs above the keyboard, indicate the sound and “color." It is recommended to have the English-sounding stops (8' octave, 8' principle, and 4' octave) turned on.

Differences from the piano
The electric chord organ is a type of home organ that has a single short keyboard and a set of chord buttons. This allows the musician to play a melody or lead with one hand and play accompanying chords with the other. The chord organ was invented in 1950 by Laurens Hammond, with the first model being the Hammond S-6 Chord Organ.
Sound Production
The piano is a percussion chordophone instrument, meaning that it produces sound through the striking of strings. When a key is pressed on a piano, a small hammer strikes a string, producing the sound. The player must continue striking keys to continue the sound, as the sound dies away quickly. On the other hand, the electric organ is an electronic keyboard instrument. When a key on an organ is struck, an electrical circuit is completed, and the key does not physically strike anything.
Pitch and Tone
The piano has a higher pitch range than the electric organ. The electric organ offers a more varied timbral spectrum and longer sustain. The piano has a distinct percussive sound, while the electric organ has a thicker tonality, especially "Rhodes"-style sounds.
Playing Style
The piano works well as a leading instrument due to the power of percussion instruments coming from the first strike. The piano can also produce rhythms and melodies much faster than an organ, making it excellent for introduction pieces and guiding the melody. The organ is capable of filling a larger space with sound and supporting a large congregation, for example, in singing. Its power comes from the sustainment of notes. A primary function of an organ is to fill in sounds and provide the supporting chords.
Dexterity and Music Theory
Each instrument calls for a different set of manual dexterity and music theory skills. While both instruments are keyboard-driven, organ players must learn to play bass notes on a pedaled keyboard while controlling a volume pedal. Piano players, on the other hand, must learn complex chords and fingerings.

How to use the chord buttons
The chord organ is a type of home organ that features a set of chord buttons and a single short keyboard, enabling the musician to play a melody or lead with one hand and accompanying chords with the other. The left hand operates the chord buttons, which are adapted from those of an accordion, while the right hand plays the keyboard.
The chord buttons are laid out in a left-hand panel, providing a range of chords for all 12 musical keys. These typically include Major, Minor, 7th, Diminished, Augmented, Major 6th, Minor 7th, and 9th chords. By pressing the appropriate button, the player can sound a full chord with just one finger, making it easier to play complex harmonies. This is in contrast to a traditional piano, where forming chords often requires playing multiple notes simultaneously.
The chord organ's chord buttons are designed to be intuitive and user-friendly. For example, the buttons are often colour-coded or labelled with the chord type, making it easy for the player to find the desired chord. Additionally, the layout of the buttons may be designed to group similar chords together, making it easier to transition between them smoothly.
To use the chord buttons effectively, players can employ a variety of techniques. One technique is to use the chord buttons to establish a harmonic foundation while playing a melody or lead with the right hand. This allows for a fuller, more complex sound than could be achieved with a single melody line. Additionally, the chord buttons can be used to create rhythmic patterns or accompaniment figures, adding texture and interest to the music.
Overall, the chord buttons on an electric chord organ provide a versatile and user-friendly way to play chords and accompany melodies. They are an essential feature of this type of instrument, allowing players of all skill levels to create rich and harmonious music.

Playing melody and chords simultaneously
Playing the electric chord organ involves using a left-hand panel with buttons to play harmony, while the right hand plays the melody. The chord organ is a type of home organ with a single short keyboard and a set of chord buttons, allowing the musician to play a melody or lead with one hand and accompanying chords with the other.
The right-hand 37-note keyboard can play both chords and single notes. The "Organ" section provides String and Flute sounds, which are polyphonic. Meanwhile, the "Solo" division allows the organist to play single-note melodies superimposed over the polyphonic "Organ" division.
To play the electric chord organ, the left hand operates an array of chord buttons adapted from those of an accordion, while the right hand plays the melody on the keyboard. The original Hammond Chord Organs from 1950 are electronic instruments that use vacuum-tube technology. The chord organ is designed to be simple to play, requiring little knowledge of organ or piano playing techniques.
To play melody and chords simultaneously on the electric chord organ, it is important to ensure that the melody note is the highest in pitch. This allows the melody note to stand out above the supporting notes within the chord. It is also helpful to practice each chord in different positions, with the 1, 3, or 5 on top, to gain flexibility in outlining a melody with chords.
Additionally, when playing the electric chord organ, it is recommended to avoid playing octaves with the left hand, which is a common practice on the acoustic piano. Instead, consider using smaller chord voicings and fewer notes to create a thicker tonality unique to the electric organ.

The different types of electric chord organ
The electric organ, also known as the electronic organ, is an electronic keyboard instrument derived from the harmonium, pipe organ, and theatre organ. It was first popularised by Hammond in 1930 with their Model A. The market for electric organs grew rapidly after World War II, with several manufacturers entering the market.
The electric organ has since evolved into several types of instruments, including the combo organ, which became widely used in popular music in the 1960s due to its small size, lightweight, and affordability.
One type of electric organ is the chord organ, which was invented by Laurens Hammond in 1950 as an electronic home organ. The chord organ has a single short keyboard and a set of chord buttons, allowing the musician to play a melody or lead with one hand and accompanying chords with the other. There were five versions of the basic chord organ, known as the "'S' series", with the "S-6" being the most popular model.
The reed chord organ, introduced in 1959, has a sound similar to the harmonium or accordion. The Optigan, introduced in 1971, is another variation of the chord organ.
Console organs are larger and more expensive electronic organ models that resemble pipe organ consoles. They have a more traditional configuration, including full-range manuals, a wider variety of stops, and a two-octave pedalboard. Console organs are particularly suitable for use in small churches, public performances, and organ instruction.
