So, play with the chord progression above and see if you can find a progression
(or several) that you like. Then, continue below ...
Now, hopefully you had fun and found some progressions you like. But if you
found it hard to choose a progression, here are some tips:
No wrong answers. The C, F, and G chords work well
together, and any progression using those 3 chords is going to sound OK.
So, don't worry about picking "correct" chords! Sometimes, we choose a
progression just for variety, so it doesn't sound just like our last 10 songs;
but if you're just starting, then you don't even have to worry about that,
because you don't have any "last 10 songs".
Chord functions. Even though any combination of these 3 chords sounds OK,
it's still true that different combinations of these chords have different
musical effects. The area of music theory called "functional harmony" is all
about this; see Chord Functions: Tonic, Subdominant, Dominant.
Fit the melody. If you already have a melody, then only certain chords
will sound good with that melody. This actually makes it easier to choose a
chord progression, because you can ignore all the possible chords which don't
sound good with your melody. In these lessons, I start with chords first,
because that's the easiest way to start, but if you're interested in adding
chords to a melody that you already have, then see
Adding Chords to Melody.
Once you have created a short C-F-G chord progression, there are several ways
you can go next:
