common chord

Music : A note accompanied by its major or minor 3d and perfect 5th. [HARMONY.] In thorough ba , the figure 3, a sharp, flat or natural, as the case may be, or the absence of any letter, character, or figure, denotes the common chord of the ba note. When there is more than one chord on the same ba note, the common chord is figured §. ( Stainer & Barrett .)
