dichord

plural dichords

1. entertainmentA chord with two notes.

   This in turn may lead to splitting the final note of the song into a dichord without the necessary existence of overlapping, but the dichord may be an interval of any kind, since it is melodically formed.

   1981, Robert Fink, The Origin of Music: A Theory of the Universal Development of Music

2. A musical instrument that has two sets of strings.

   Many modern instrument collections contain instruments shaped like eighteenth-century trumpet marines, but which might better be described as dichords equipped with common string instrument bridges so as to be played as basses.

   1991, Cecil Adkins, A trumpet by any other name: a history of the trumpet marine

3. An ancient two-stringed lute.
