In music theory, a chord is a group of three or more notes played together to create harmony. A key defines the tonal center of a piece of music. A chord detector shows you the chords as they change throughout a song, while a key detector identifies the overall key of the track. For example, a song might include chords like A, E, and D, but still be in the key of A. Both tools are useful and often work best together.
