Chord Sequence to Fit a Melody
The first chord to add is the easiest. It is also the last. The last chord of the piece should be a Tonic (I). This chord feels like «home» and is the best chord to finish a composition with.
The chord before that is often a Dominant (V), but we’ll see what fits our melody best first.
Let’s keep it simple.
We will add a chord only to the first note in each measure, unless you have a lot going on; then you might want to add two for each measure.
This is how you find where they fit:
- What note is in the melody where the chord should be added?
- Use the chord that contains that note.
- If there are more than one chord that fits, look at the neighboring notes. If there are more notes from one chord, use that one.
It is also useful to know that right before a Tonic chord (I) it sounds great with a Dominant (V), if it fits the melody.
And before the dominant chord it often sounds good with a Subdominant (IV). This gives you the standard IV-V-I cadence.
Keep it simple! As you learn more you can experiment with other chords, but for now just use the three basic triads (I, IV, V).
Remember that you can always just try it by playing/singing and see how it fits, but it is kind of fun to see how well the musical composition will sound even without playing it as you write!
It is always such a pleasure to hear the end result, and how amazing it sounds even by working only with these simple rules with only a pencil and staff paper!
So for my example, I found this chord sequence fits the tune (the circled notes are also found in the chord). The chords are written as capitals above the melody:
As you can see sometimes the whole measure has all the notes of one of the chords, so it is easy. But in the measure before the last I could use both a G and a C chord.
Because I know that it works great with a G chord (the Dominant, or V in C major) right before the last C chord (Tonic, or I chord in C major), since it gives the very plain but nice V-I chord sequence, I choose the G chord.
Once you find where the chords fit your melody, you have all you need to make a great arrangement. Actually, it is great as it is too- sing the melody and play the chords with a guitar or a piano. Voila!
But of course we will do more!
