The note upon which a triad or chord is built.

In music the root (basse fondamentale) of a chord is the note or pitch upon which that chord is perceived or labelled as being built or hierarchically centered upon. This feeling of centeredness is aurally perceivable for those who grew up with European music, and its verbal labelling is a basic skill for the musically trained.
