The double-keyed pipe organ is recognized as the king of musical instruments in the international music industry. The double-keyed electronic pipe organ (referred to as double-keyed pipe organ) is a new generation of electronic pipe organ. It has richer timbre and more powerful function. The double-row keyboard has two rows of keyboards on the hand and a row of keyboards under the feet that need to be played with both feet. Each row of keyboards can play the tones of various musical instruments. It is extremely anti-traditional. By dancing on three rows of keyboards with both hands and feet at the same time, it can play the effect of a hundred-person symphony orchestra (including electroacoustic orchestra and folk orchestra), and can complete almost all musical expressions by itself. It is extremely subversive to the traditional playing mode. Known as the new generation of "king of musical instruments", the double-row key (electronic pipe organ) originated from the pipe organ. There are two rows of hand keyboards on the top and a row of large pedal keyboards on the bottom. The pedalboard arrangement is the same as the hand keyboard, and can be played with the left foot or the toes or heels of both feet. There are one or two expression pedals on the right side of the front of the pedalboard, which are used to control volume, expression, tone switching, portamento, etc. There is a knee lever at the bottom of the hand keyboard to control sustain. The electronic organ has hundreds of timbres, and the sound quality is close to that of a real instrument. And the timbre can be edited according to the needs of the music, such as the strength of the note head, and the speed and amplitude of the string vibrato. Each row of keyboards can be stacked with several different tones. The way it is played makes it possible for multiple parts to be played simultaneously with different timbres, thus simulating the performance of a large band. The music sounds rich and complex, but every note is played live by the performer. It has a powerful rhythm editing function, which can freely edit the percussion part of the music. Its keyboard is very sensitive, with various parameters such as pre-touch sensing, after-touch sensing and horizontal touch sensing. This provides more space for the performance of the music and also increases the difficulty of control by the performer. Although the development of double-row keys started relatively late in China, it is being known and loved by more and more people for its excellent performance and rich musical expression.

In the musical instrument family, the double-row key is a young member, and it is also one of the most vital and musically expressive instruments. In a certain sense, the double-row key is like a The Musical Instrument Museum has room for improvement and is a perfect combination of music performing arts and modern electronic technology. In addition to the functions of traditional musical instruments, the double-row keys also have unique functions in terms of musical expression, music entertainment and music innovation, and are more characteristic of the times. The dancing performance form of double row keys, the eclectic music style, the varied timbre simulation, and the rich and colorful sound effects are all amazing. Its upper and lower keyboards and pedalboards that can be used by both hands and feet, and its more humane musical performance, correct the shortcomings of other mechanical and karaoke-style keyboard instruments that are inflexible and lack change. The pipe organ is the ancestor of the piano and even all keyboard instruments. Pianos and other keyboard instruments are all developed from the pipe organ. The double-row electronic pipe organ will have immeasurable development prospects.
