Quick Answer: 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". 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. For example, using an Ionian • 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, • the sixth note the vi minor chord, • the seventh note the vii diminished chord and • the octave would be a I major chord.__###newline###__ Using the minor one would have: • i minor, • ii diminished, •III major, • iv minor, • v minor, •VI major, •VII major and • the i minor an octave higher.__###newline###__.
