Well, it’s not an event as such, but it makes for a great blog title, right?!
Today we develop the Main Theme of our piece. In music, a theme is usually a melody but it could refer to an accompaniment or even just a rhythm, but we’ll stick to something conventional this time.
How is a melody created?
My first task is to decide how often to have different chords played. Most of my tonal pieces have one chord per bar (or measure). In our piece, that would mean we play a G Major chord for four beats (a G Major chord is made up of the 1st, 3rd and 5th notes of the G Major scale – refer to last week’s post for info about that, or check out Wikipedia for a communal explanation about chords).
In the second bar, we’d play a different chord, but one that is closely related to the previous one. Perhaps D Major. Maybe then back to G Major, followed by C Major, and for the next four bars, G, C, D and finish on G again.
This is what it would sound like:
However, there are other options, and I’ve opted for a pretty challenging one: to make the melody an eight-bar phrase but keep the same chord throughout. It’s possible! A lot of classical era composers managed it, so I’m going to attempt it. Why is it a challenge? It’s going to be tough to make it interesting and likable over such a long period of time.
First, just for reference, the primary (root) note of each chord is placed in every bar in the bass part. I can build the composition from there. In some complicated pieces I’ll add a piano part with all the notes of the chord in it but delete the piano part before I finish.
Now I’m taking the chord of G Major and making up a rhythm as I plug in notes from the scale of G Major into the violin part. It’s that [easy]. Here’s our main theme:

Notice how the first two bars repeat in bars 5 & 6 – that creates familiarity and gives the listener something to hold onto. The melody also ends on G, the root of the home key. Next we will add the second theme and expand the exposition, adding things like ‘bridges’ and ‘interludes.’ Exciting stuff! Really !!!
