This topic comes from a viewer question. Connie asks, “How do I get beyond the I, IV, and V chords when improvising Christmas music.” I thought this would make a great topic to cover all sorts of music and improvisation.
Before we begin, you might be wondering what the I, IV, and V chords are. Well if you are in C major, an I chord is built on C (C -E -G). The fourth note in the C major scale is F, so the IV chord is built on F (F – A – C.) And the V chord is built on G (G – B – D). These are referred to as primary chords, they are major triads and you can harmonize almost anything with the I, IV, and V chords!
In the video accompanying this article, I show an example of harmonizing using this technique with the song “On Top of Old Smokey” in A major. I use the I, IV, and V chords to create a simple harmony to accompany the melody. In A major that is the A major chord (A – C-sharp – E) the D major chord (D – F-sharp – A) and the E major chord (E – G-sharp – B). But what other chords could you add beyond the I, IV, and V?
You can start by using the secondary chords. Secondary chords are pretty much the rest of the chords beyond I, IV, and V. So they would be II, III, and VI-VII not so much because it’s diminished. The II, III and VI are minor chords. So in A major, the II chord is B minor (B – D – F-sharp), the III chord is C# minor (C-sharp – E – G-sharp), and the VI chord will be an F# minor (F-sharp – A – C-sharp). But where can you use these in the harmony?
The best thing to do is experiment. Try different combinations and see what sounds good. You can try substituting an II chord for the IV chord; you could even keep the same D in the bass inverting the chord. This creates a seamless change in harmony with a new flavor!
The beauty of improvisation is that there are no absolutes of right and wrong. While some combinations won’t sound as good as others, you can experiment and find out what sounds good to you. Keep working at it and eventually creating new and interesting sounds will become second nature.
