In music, harmonization is the chordal accompaniment to a line or melody: "Using chords and melodies together, making harmony by stacking scale tones as triads".^[2]

A harmonized scale can be created by using each note of a musical scale as a root note for a chord and then by taking other tones within the scale building the rest of a chord.^[3]
For example, using an Ionian (major scale)

• the root note would become the I major chord,
• the second note the ii minor chord,
• the third note the iii minor chord,
• the fourth note the IV major chord,
• the fifth note the V major chord (or even a dominant 7th),
• the sixth note the vi minor chord,
• the seventh note the vii diminished chord and
• the octave would be a I major chord.

Using the minor (aeolian mode) one would have:

• i minor,
• ii diminished,
• (♭)III major,
• iv minor,
• v minor,
• (♭)VI major,
• (♭)VII major and
• the i minor an octave higher.^[4]
