👉 The term "multichord" is a term used in music theory and notation to refer to an instrument or musical device that consists of several strings, often tuned to different pitches. The name "multichord" comes from its resemblance to a multi-colored, multicolored light source, which can be seen as a representation of the various notes on a musical instrument. In music theory, a multichord is typically used in two parts: the left-hand part and the right-hand part.
