What rhymes with harmonising?
har·mon·is·ing

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 (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.
