Keyboard bass
Keyboard bass (shortened to keybass and sometimes referred as a synth bass) is the use of a smaller, low-pitched keyboard with fewer notes than a regular keyboard or pedal keyboard to substitute for the deep notes of a bass guitar or double bass in music.
History[edit]
Early keyboard bass[edit]
The pipe organ is the first, and the forefather of keyboard bass instruments. The bass pedal keyboard was developed in the 13th century. The keys for the hands are also capable of playing very low pipe tones.
