Major Scale Chords
Harmonizing a major scale means to take the notes of a major scale and create chords based on that scale. This will create seven chords (one for each note of the scale) that each contain only notes from that particular scale.
Here’s how we do that. Let’s use C major as an example, in other words the key of C. Write out the C major scale for about 1.5 octaves: C, D, E, F, G, A, B, C, D, E, F, G.
Then starting on the first note (C), select the first, third and fifth note (C,E,G)
Then take the second note (D) and do the same (D, F, A). You will end up with the following:
C Major: C, D, E, F, G, A, B, C, D, E, F, G

We end up with a series of seven chords, of which all the chords are limited to the notes in the C major scale. It makes sense then that these chords would harmonize very well with a melody played in C major, as both the chords and the melody contain the same notes.
