A chord and its related scale (or mode) are different expressions
of one and the same tonality.
The scale or mode is a horizontal expression, the chord is
a vertical expression of that
tonality.The complete chord contains, like the scale, all the notes that constitute the
tonality.
The complete Cm13 chord for example, contains the same notes
as the C Dorian mode.
